There is a problem with one account. Whenever mail is sent to this account, it is returned as undeliverable with this error:
Command died with signal 7: "/usr/lib/dovecot/deliver"
I checked the dovecot log, but everything looks fine. All of the other accounts are working fine. And this account was working fine until a few days ago. Any idea what happened/how to solve this? Thanks.
