Description Daniel Tröder

2015-11-11 15:45:01 CET

Listener creates Maildir in wrong location:

mailPrimaryAddress=a@b@uni.dtr →
/var/spool/dovecot/private/b@uni.dtr/a

dovecot-imap has no problem:

# fetchmail --check --nodetach --protocol IMAP --all --keep --username a@b@uni.dtr 10.200.3.18
[..]
fetchmail: Keine Post für a@b@uni.dtr bei 10.200.3.18

But dovecot-lmtp seems to have a problem:
