I use postfix to put the email in /var/spool/mail, and dovecot to provide
pop3 access on one system and imap on another.

Don't forget to alter /etc/postfix/aliases and run the newaliases command.

Are you using it with a database backend?

I am using Mageia as my main server and postfix has never worked for me since I upgraded from M8!

I'll try to investigate it deeper, but please confirm what database backend you are using.

Update:

Good news is that it works now :)

It was weird that it did not work yesterday, so I have decided today to reboot the server. After rebooting, postfix started perfectly, however still could not use mariadb backend. After digging into the issue, I have found out that postfix in M9 is running in chroot, Now I cannot tell if it was running in chroot on M8 or M7 where it always worked perfectly. So All I had to do is to bind-mount the mariadb socket directory to postfix chroot.

Thank you.

I do not know, whether to mark it as invalid, worksforme or what!

Status: NEW => RESOLVED
Resolution: (none) => INVALID

Glad it's sorted.

Invalid is the correct resolution, as nothing Mageia provides was changed to
fix it.

I think it was Mageia 3 where postfix switched to running postfix in a chroot,
but I could be wrong about that.

What are you using the sql database for? The user aliases map?

Thank you, I still find it weird that upon upgrade postfix did not work though!

Anyways, it is sorted now as you said.

I am using the database for aliases, domains, restrictions, users, quota...etc. Everything is configured using the sql database.
