dovecot - Apr 2006 - Dovecot LDA - Performance/issues versus postfix delivery? Also, installing on OS X?

Can anyone give me an idea of whether or not dovecot-lda can solve the 
following issue: We seem to have constantly-corrupting dovecot* files 
for people who fit one (or more) of the following categories:

1) 1000+ message inboxes;
2) multiple clients simultaneously checking mail;
3) people receiving a lot of mail, and/or the server receiving and 
trying to deliver a single message to all users at once

We're using straight postfix maildir delivery, and while the mail keeps 
coming, we start to see a lot of "temp.xxxx.xxxx.xxx" type lockfiles 
build up after any inconsistencies appear in the Inbox indexes, and 
clients start to report timeouts and/or crash as a result. Would 
switching to LDA by itself resolve this issue (on the argument that 
delivery would ALSO update the indexes every time), or is there some 
more fundamental issue we are having that is causing the inconsistency 
to arise?


On a related note: I noticed the darwinports version of 1.0beta7 does 
not include the code for dovecot-lda... Does anyone have experience 
setting this up?

Thanks!

This has the smell about it of bad locking.  Are you absolutely certain that 
both postfix and dovecot are using the _same_ locking scheme?

Oh, and is the mail store local, or on NFS?
