dovecot - Feb 2012 - Where did the message end up?

Hi all!

Just migrated out UW-IMAP installation to Dovecot and so far so good.

Had small teething problems though which left me with one question.

The scenario was that I have a set of public folders that are only needed by 
the main company group (gid = company). Then there are some external users as 
well, not directly in the company group.

I set up the public mailbox with permissions 660, owner me and group 
"company". That is the externals didn't have access to the mail
folder.

At this point all looked fine, but later there was an email to an external 
person and this was passed on to deliver by procmail. Procmail logs says all 
was OK, but there is an entry about the public folder not accessible in the 
Dovecot log. The email is nowhere to be found.

My question:

Where is the delivered email?

Best
Dag

So this is in a public namespace?

Exact error message would be helpful. Was the error from deliver, or imap/pop3?
If it was from deliver, it probably returned temporary failure.

Have you checked what happens if deliver tempfails (e.g. make procmail call
tempfail.sh script that just exits with 75), does procmail also correctly
tempfail and tell MTA to retry the delivery later?
