Co-domain email aliases don't work.

[zxspec]

Hi.

I have a maindomain.com and a codomain.com setup, Ive checked the virtualuser table and the email addresses are both showing on this file as:

info@maindomain.com web20_mainuser
info@codomain.com web20_mainuser

If I send an email to info@maindomain.com it arrives
but if I send an email to info@codomain.com it doesn't arrive.

I've checked the maillog and no error seems to show up, the only thing I noticed is that Postfix only logs the information when I send an email to info@maindomain.com, there's no log info regarding the email sent to info@codomain.com


What might I be missing here?

Thank you

Did you create www.codomain.com AND codomain.com as codomain (BOTH)?

Yes I did. Both

Please check if the MX record of codomain.com is pointing to the right server. You can check that with
dig mx codomain.com
