dovecot -n is below. dovecot takes care of delivery, through LMTP.
Additionnal thoughts on possible problems:
- one of the users was using mutt locally and accessed its mailbox directly
without going through dovecot.
- I experimented dsync replication from another machine that was not
accessible through POP/IMAP/SMTP, perhaps this is what caused chaos?
