email does not arrive in maildir folder

Hi

I have several domains and email accounts on my server.
Some of these domains work. But on some the email doesn't get written in the maildir folder.

Also deleting and recreating in ISPConfig didn't help with these email addresses.

output of ehlo localhost:

output of /var/log/mail.err:

Thanks for your help!

 

solved

I found the problem in /etc/postfix/virtusertable

There was a typo in co-domain.
