So I think I figured out the problem.
What was happening was that db4 was having issues (don't know what in particular) but it was causing lmtp to hang because lmtp was waiting for the duplicate delivery check to complete and it never did because of whatever issues db4 was having. So I switched the db type for deliver.db to skiplist and now all seems to be working well...
Default Recommended?
--with-duplicate-db=DB db3_nosync skiplist
--with-mboxlist-db=DB db3 skiplist
--with-seen-db=DB flat skiplist --with-subs-db=DB flat
--with-tls-db=DB db3_nosync
Going through past emails, it seems now that skiplist is recommended essentially for everything. Is that plausible? Comments?
No, skiplist isn't recommended for everything. Rob posted a message multiple times with the current recommendations (which are the defaults in 2.2), and the reasons why.
In a nutshell:
Recommended --with-duplicate-db=DB db3_nosync --with-mboxlist-db=DB skiplist --with-seen-db=DB skiplist --with-subs-db=DB flat --with-tls-db=DB db3_nosync
The simple reason for this setup is that skiplist performs very well for when enumerating a database and BDB works very well for random access.
