[Dovecot] Problem with sieve: Keep: Generic Error

Mon Dec 15 15:27:58 EET 2008

OK, finally I tracked that bug down. The underlying problem is as I supposed
namespacing (my namespace prefix is "INBOX."). In sieve_keep (sieve-cmu.c),
the mailbox name is fetched from sieve_msgdata_t and then transferred to
deliver_save (deliver.c). The problem is, that the default mailbox name in
sieve_msgdata_t is - according to my namespace - "INBOX.". But deliver_save
and mailbox_open_or_create_synced don't like that trailing dot, which leads
to an error. This leads to default saving in the user's inbox, so in fact
there happens what would happen anyways - but there's an error put out.

Generally, I think that this should be fixed in deliver which should strip
trailing separators automatically when needed.
Also I think that saving to INBOX instead of some other folder should be a
no error but a warning. It should also be considered that for now, if using
plus-extensions with delivers' -n option, when a folder doesn't exist and
the mail is put into INBOX instead, an error is put out - although being
perfectly desired behavior. Deliver should put out some warning in the log
file instead of "/* silently store to the INBOX instead */" at line 225 and
then leave without error code.

Thomas
