Can you expand on this?
I have been running Dovecot on a MacOS 10.4 PPC machine with Maildir
on local (HFS+) disk for some time and have had intermittent and
hard-to-characterize problems that manifest themselves as clients
(Eudora, Palm VersaMail, and Outlook) timing out and hanging as one
tries to move messages between mailboxes in the same account. The
cargo-cult approach I've used to eliminate the hangs has been
unsatisfying (cycle all clients and Dovecot, remove index files and
temp files in mailbox directories) but even with rawlogging I have
been unable to nail down the source of the trouble definitively. It
looks like maybe bad index files or maybe some sort of locking issue,
but the logs don't show anything other than the clients timing out
and dropping connections.
I don't understand the description of those rc16 changes because it
seems like dotlocking would be irrelevant for Maildir anyway. Should
I set dotlock_use_excl=yes even though I'm using fcntl?
