email does not arrive in maildir folder

[torusturtle]

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:
250-pollux.kynamoo.ch
250-PIPELINING
250-SIZE 10240000
250-VRFY
250-ETRN
250-STARTTLS
250-AUTH LOGIN PLAIN
250-AUTH=LOGIN PLAIN
250 8BITMIME

output of /var/log/mail.err:
Apr 24 18:19:54 pollux courierpop3login: LOGIN FAILED, ip=[::ffff:84.72.101.110]
Apr 24 18:20:20 pollux last message repeated 23 times

Thanks for your help!

solved

I found the problem in /etc/postfix/virtusertable

There was a typo in co-domain.
