Can I have my own custom domain-based address(es) in a Mailfence account?

Yes, we do support having your own custom (or vanity) domain-based address(es) in paid plans.

Custom domains per plan
Custom domains per plan

Please be aware that the domain foo.example.com and example.com will be counted as two separate domains, each with its own DNS records.

Before adding a custom domain, please make sure that you have already chosen a primary address (in Messages) for your Mailfence account.

Since 2023, we’ve introduced our new short domains “@mf.me”! If you want to learn more and how to get yours, check out our full guide here.

Also, please make sure that your account’s reset/notification address is not based on the domain that you are about to add. If yes, then change your reset/notification address with a different service (e.g., notmydomain.com) – as mydomain.com DNS MX records will point to our servers and you will no longer be able to change password of your account in case of compromises.

A TXT record is a type of resource record in the Domain name system (DNS). Read more here. Please refer to your domain name service provider documentation to get exact steps on how to add a TXT record.

DNS records can take some time to propagate. You can use this tool to check.

6. Setup DNS SPF & DKIM records by following steps from this KB article, to ensure deliverability of your emails. This is a compulsory step.

7. You can now create your domain based email address(es) as an alias to your Mailfence account, by clicking on New.

custom domain based address: step 7
  • This is a compulsory step if you already use your domain for e-mails, otherwise incoming e-mails to your domain based e-mail address(es) will be lost.
    • Emails sent to postmaster@mydomain.com will arrive in the mailbox of mydomain.com domain owner.
    • Emails sent to abuse@mydomain.com will not arrive in the mailbox of mydomain.com domain owner. This address is reserved for anti-abuse reasons.
  • To set up a catch-all address for your domain, select any of the existing addresses in the catch-all column.
custom domain based address: step 7.1
To replace your Mailfence account primary email address to your domain based address, click on “Manage my addresses” → Click on “…” next to the address that you would like to set as primary address → “Set as primary”.

8. Add both of the provided DNS MX entries in your domain DNS records.

Once done, click on Verify.
  • Make sure you enter the same preference value (e.g. 10) in both of the MX records to facilitate load balancing and fail over on Mailfence’s side.
  • In some cases (depending on your domain DNS record manager), you will have to add the ‘.’ (dot) at the end of the MX records. Without them, the MX records will be faulty e.g., (smtp1.mailfence.com.mydomain.com).

After following above steps, you will be able to receive emails sent to your domain based address(es).

You can also create/manage other user accounts, and assign the email address(es) based on your custom domain.
