Any chance you're getting locking problems with mail delivery, perhaps when an
IMAP reader looses it's connection and the daemon is sitting there waiting for
a timewhen when a LMTP delivery attempt is made?
If you want to debug LMTP further, start with this section of "man lmtp":
TROUBLE SHOOTING CONTROLS
debug_peer_level (2)
The increment in verbose logging level when a remote client or
server matches a pattern in the debug_peer_list parameter.
debug_peer_list (empty)
Optional list of remote client or server hostname or network
address patterns that cause the verbose logging level to
increase by the amount specified in $debug_peer_level.
error_notice_recipient (postmaster)
The recipient of postmaster notifications about mail delivery
problems that are caused by policy, resource, software or proto-
col errors.
