• My emails are not working, help!

    In the vast majority of cases this is simply due to a bad DNS configuration. Please check out our DNS settings page. You might also find one of the following domain provider guides helpful:

    To test your setup, please have a look at "How do I know if my DNS is set correctly?" below.

    If you're still in trouble, know that we offer to do the DNS configuration ourselves for our premium users. This requires for you to provide us with your registrar (i.e. domain provider) credentials though, so we can access your domain DNS editor.

  • The emails I send end up in the SPAM folders of my recipients!

    If your emails are delivered but they end up in the SPAM folders of your recipients, it is very likely due to a bad configuration (or an absence of configuration) of either your SPF DNS record or your DKIM DNS record, or both.

    To fix this, please see "How do I know if my DNS is set correctly?".

  • How do I know if my DNS is set correctly?

    If you've haven't validated your MX record yet, please visit https://postale.io/fr/configure/yourdomain.com to validate your MX record first (replace yourdomain.com with your actual domain name).

    Once your MX record is validated, login to the admin interface (with a domain administrator account) and click on the DNS diagnostic button in your domain page. This will show you everything you need to know about your domain DNS settings and what you need to fix.

    For alternative ways to check if your records are set properly, you may use some third party testing tools, such as dnschecker.org or the excellent mail-tester.com.

  • What's a DNS, and why do I need to configure it?

    A Domain Name Server is a service acting as a directory for websites and other internet services. When you enter the name of a website in your web browser, say "google.com", your browser first asks to a DNS where it can find that site (i.e. what's the IP address of the server serving that particular site). The same thing goes for emails. When you send an email to someone, say to "maryline@poupoupidou.com", your mail client (Gmail, Outlook, ...) first asks a DNS service where to actually send the email (i.e. what's the server handling emails for "poupoupidou.com").

    Thus, any domain with email addresses needs a DNS configuration.

    If you're using postale.io for your domain emails, you need to set your domain DNS records so that mail clients everywhere in the world know that emails sent to your domain are handled by postale.io mail servers. Usually, only people knowing the domain provider (a.k.a registrar) credentials used to purchase a domain name have the ability to edit DNS records for that domain.

    The main DNS record for emails is called an "MX" record. For websites, it's called an "A" record. There are many more records for different purposes. To configure your DNS properly, please visit our DNS configuration guide.

  • What's an "MX" DNS record?

    It's the DNS record for mail servers. It tells what mail server(s) handle emails for a given domain name. To know the right MX records you need to use our services, please have a look at our DNS configuration guide.

  • What's an "SPF"?

    This is another DNS record used for emails. Quoting Wikipedia: "Sender Policy Framework is an email authentication method designed to detect forging sender addresses during the delivery of the email.". It basically gives the emails you send a better score and a lesser chance of being seen as SPAM. To know the right SPF records you need to use our services, please have a look at our DNS configuration guide.

  • What's a "DKIM"?

    This is another DNS record used for emails. Quoting Wikipedia again: "DomainKeys Identified Mail (DKIM) is an email authentication method designed to detect forged sender addresses in emails [...].". Similarly to SPF records, it gives the emails you send a better score and a lesser chance of being seen as SPAM. To know the right DKIM records you need to use our services, please have a look at our DNS configuration guide.

  • Are SPF, DKIM, and DMARC records required?

    Technically, they're not. Only the MX record is required. But SPF, DKIM, and DMARC are strongly recommended, as without them the emails you send have a much higher chance of being considered as SPAM. If you set those records, it's very unlikely than any (legitimate) email you send land in the SPAM folders of your recipients. To know the correct records you need to use our services, please have a look at our DNS configuration guide.

  • My Sendgrid/Shopify/(any other third party service) emails don't get delivered!

    If you're using a third party email service like Sendgrid, Shopify, another service or your own server to send emails from @yourdomain.com email addresses, you'll need to add that server to your SPF record. Just add "include:some.third.party.server.com" right before "~all" in your SPF record. Like so:

    "v=spf1 mx include:some.third.party.server.com include:some.other.server.net ~all"

    The SPF record above will allow some.third.party.server.com and some.other.server.net to send emails on behalf of your domain name (i.e. from @yourdomain.com email addresses, where yourdomain.com is your domain name). The "mx" part says the server specified in your MX record (which in your case is "mail.postale.io", our service) is also allowed.

    If you're using Sendgrid, the server(s) you need to add to your SPF record is/are given in your Sendgrid account. See Sendgrid's documentation here.

    If you're using Shopify, the server you need to add to your SPF record is given in Shopify's documentation here. You need to keep the "mx" part in your SPF record so the resulting record is: "v=spf1 mx include:shops.shopify.com ~all".

    You should also avoid using "reply-to" email addresses having a different domain name than the "from" email address. This tends to raise antispams red flags, especially if your SPF doesn't allow the sending server to send emails from your domain name. This could mean someone is not only trying to impersonate you/your company but is also trying to get replies (i.e. it looks like a phishing attempt).

  • Where can I change the DKIM for my domain?

    On your admin interface, in the domain settings page (you need to be a domain administrator to have access to this). If you change your DKIM, please make sure to update your DNS record accordingly.

  • What are the credentials to connect to the admin interface?

    Your username is always your domain email address. For your password:

    • If you are the first user registered on postale.io for your domain, you received your password by email at the personal email address you've used at registration. If you didn't receive the email, or if you've mistyped your personal email address, please contact us.
    • If you are not the first user registered on postale.io for your domain, your password has been set by the domain administrator who created your account. Please contact him/her to get your password.

    Note that you can always change your password from your admin interface.

  • What are the credentials to connect to the webmail?

    Same answer as for the admin interface. The credentials for the webmail and the admin interface are always the same.

  • I can't get my emails to work on my Gmail/Outlook/Thunderbird/Something mail client!

    Open your mail client, and find the menu/button to add an account. The interface will ask for your username (that's your full domain email address) and your password. Enter them.

    From there, most commonly used mail clients should be able to autoconfigure everything for you, thanks to our built-in autoconfiguration feature. If they don't autoconfigure, they'll ask you to provide some settings instead. Namely: SMTP server and port, POP or IMAP server and port, and SSL/TLS settings. All the settings you need to do that are provided on our mail client configuration guide.

  • Where can I create/edit/delete email accounts for my domain?

    On your admin interface. Only if you are a domain administrator will you be able to act on other email accounts of your domain.

  • I need to create more than 2 mailboxes and 3 aliases for my domain / I need more than 1 GB per mailbox.

    You can drastically increase your account capabilities right now by subscribing to one of our premium plans. If that doesn't fit your needs, feel free to contact us and tell us what you need exactly. We'll try to accomodate you if we can.

  • Help, I forgot my password!

    If you're a regular (i.e. non admin) user please contact your domain administrator, as he/she can reset your password from his admin interface. By default the first user registered on postale.io for a given domain is a domain administrator. However other administrators can be added later by any domain admin.

    If you are actually the first domain admin you can get a password reset link from our forgot password page. Alternatively you can contact us.

  • I know my password but it's not working anyway!

    If you're absolutely certain you're using the right credentials to login but it's not working anyway, it means a domain administrator has changed your password. Please contact a domain administrator.

  • Where can I change my password?

    On your admin interface, in the 'My account' page. Credentials are the same as for the webmail.

  • Where can I change email settings such as automatic replies and redirections?

    On the webmail, in Settings > Filters, or on your admin interface, see the 'Sieve filter' section on the email account settings page.

  • Can I make custom rules/filters on emails I receive (to filter SPAM for instance)?

    Sure! You can easily make rules from the webmail, in Settings > Filters.

    For instance you could make a rule to automatically remove all emails containing a particular text, or having a particular subject, or sent from a particular email address. Or automatically move them in say the Trash folder.

    That filtering interface in the webmail is very intuitive to use and requires no knowledge. When you make a filter with it, behind the scene it writes in the Sieve script of your email account.

    If you need more advanced rules, you can also direclty write in the Sieve script yourself. That's done from the admin interface, in the email account settings page, click on the 'Custom email filter' button within the 'Sieve filter' section. Since both the webmail and the admin interface write in the same Sieve script, you can interchangeably use both ways to make rules.

  • How long do emails stay in the Trash and Junk folders?

    30 days! All emails in the Junk and Trash folders older than 30 days are automatically deleted. This is a common practice, helping you to keep your storage usage under control.

  • How to set a catch-all address for my domain?

    Connect to your admin interface with a domain administrator account. Click on your domain then on 'Edit settings', check 'Domain catch-all' and choose a target email.

  • How come a non domain administrator can access the admin interface?

    If you're not a domain administrator, you're admin interface will only allow you to modify settings related to your own account: change your password, set an out of office automatic reply, etc.

    A non domain administrator does not have access to any action on other accounts of the domain or on the domain settings. Only domain administrators have such options.

  • Do you support automatic aliases such as name+tag@domain.com (a.k.a sub-addressing)?

    Yes! We support sub-addressing with the "+" (plus) character.

    For instance if you created an email address john@wayne.com, any email sent to an address of the form john+tag@wayne.com will be received by john@wayne.com as well, with tag being any word you like. You can even use multiple tags, like john+west+saloon@wayne.com.

  • Can I use my domain email address with Gmail?

    Sure! Open Gmail and click on Settings > Accounts and Import > Check email from other accounts > Add an email account. Enter your domain email address and follow the steps.

    When asked to enter your username, enter your full domain email address again (that's including the @yourdomainname.com part). Other settings you'll need are listed here. Please note that Gmail only supports POP.

    You can also find a guide from Google here.

  • Can I have a profile picture with my domain email address?

    Yes, absolutely. However, please note that profile pictures actually depend on the email client used by your recipients.

    With Gmail for instance, only people using Gmail to open your emails will see your Google account profile picture (or people using another mail client also showing up the Google profile picture). If you'd like that to happen with your domain email address as well, you have two options:

    • Add your domain email address as an alternate email in your Google account (then your usual Google account profile picture will show up to Gmail users when you send from your domain email address).
    • Create a new Google account with your domain email address (select the "Use my current email address instead" option) and add a profile picture to it (then that profile picture will show up to Gmail users when you send from your domain email address).

  • How to enable push notifications on my phone/tablet?

    We support push notifications/device syncrhonisation via Exchange ActiveSync, a protocol initially developed by Microsoft but nowadays open to everyone.

    To enable it, simply add your domain email address as an Exchange account on your phone or tablet. See this Android guide or that iOS guide for detailed steps on each platform.

  • How to enable autoconfiguration for mail clients (Outlook, Thunderbird, ...)?

    Mail clients can autoconfigure themselves from only your domain email address and password. To benefit from this feature your domain DNS must have two CNAME records respectively named "autoconfig" and "autodiscover", both pointing to "mail.postale.io". See the DNS guide or the DNS diagnostic tool for details.

  • How to add more domains to my account?

    Currently only premium users can have multiple domains in a single account. Free accounts only allow one domain. However you can create a free account for each and every one of your domains if you wish to.

    If you're a premium user, login to the admin interface and click on Domains > Add a domain.

  • I just upgraded to premium. Can I group all of my other domains/free accounts in my premium account?

    Sure! Login to the admin interface with your premium account and click on Domains > Add a domain. Enter the domain name you want to add and follow the ownership verification step.

    This will attach the free account domain with all of its mailboxes and aliases to your premium account, just as if you had created them from the premium account directly. You'll then be able to manage that domain and create more mailboxes and aliases for it with your premium capabilities.

  • Can I use your service to send SPAM?

    No! We have the Rspamd anti-spam software watching things, and we're constantly monitoring for abnormal activity. We reserve ourselves the right to suspend or ban any person using our services to send SPAM compaigns, phishing attacks, or any fraudulent emails. This is mainly to ensure that we stay out of domain blacklists (DNSBL), thus preserving all of our users from being considered as spammers.
