My user account in UCS has suddenly stopped accepting email since updating to UCS5.03.
The server is configured with Kopano.
Looking at var/log/mail.log I can see Postfix can no longer find my mailbox.
The error is “Recipient address rejected: User unknown in virtual mailbox table;”
Its the ONLY user account with the issue, all other mailboxes are receiving email normally.
Reading other forum entries about similar problems refer to issues with univention postfix template changes but Im not familiar with messing with that stuff.
Any suggestions welcome.
