LDA completely eliminates lock contention.
As we have discussed before, using the LDA does not prevent lock
contention, it just prevents the problems that arise when different
software is using different locking strategies on the same mailbox
(assuming nothing except LDA and imap is touching the mailbox directly).
There are valid reasons for not using the LDA: the OP might be already
using procmail, for instance, and have users with procmail recipies
which sort into IMAP folders. These folders will need to be locked by
procmail even if the default delivery to INBOX is changed (globally) to
happen through dovecot-lda. While migrating to sieve (and mdbox, and
LMTP) would, IMHO, be the best long-term solution, this isn't necessarily
something that can be set up overnight.

Thanks for your replies. I switched to Dovecot LDA this morning, but
the issue still persists, albeit logged slightly differently by Dovecot
now instead of Postfix:
"save failed to INBOX: Timeout while waiting for lock"
The reason is because some pop3 clients are holding their connection for
5 or 6 minutes (don't ask me why - and the iPhone seems to be the major
culprit).
In dovecot.conf I changed:
mbox_lock_timeout = 300
to
mbox_lock_timeout = 600
Which seems to have helped. I am unclear if this value only applied to
Dovecot LDA or if it would have worked previously before switching to
Dovecot LDA?
