Can't create user 'mail'

Hi everybody

I am setting up a email server with postfix/dovecot and roundcube. The installation was successful so far and I can send and receive emails :slight_smile:

Since I’ve created (years ago) my main mail addresses in the company and family with a user ‘mail’, I have to migrate these addresses to my FreedomBox.

Problem Description
As I did try to create a user ‘mail’ (in system – users and groups) it did say that this is not possible, because ‘mail’ is allready taken or reserved. The same thing happened when I did try to create an alias named ‘mail’.

Does anybody have an idea to however create a user ‘mail’? I couldn’t find anything on the web.

Edit 1: I did try to send an e-mail to my mail account mail@… , but it didn’t arrive. Postmaster and other aliases work and they end up in the admins mail account. Shouldn’t mail@… not at least also arrive in the admins mail account like postmaster, info, etc.?

Thanks a lot!

David
