I have a mailbox with an ungodly number of small messages in it. When new messages are delivered lmtp kicks up an error like the one below. I tried raising the vsz_limit for lmtp but that didn't see to help.

That should help.

# ls -lah dovecot.index.cache -rw------- 1 vmail vmail 128M Jul 29 20:16 dovecot.index.cache

default_vsz_limit = 256 M service lmtp { inet_listener lmtp { port = 24 } vsz_limit = 256 M }

Did you try higher than 256M? There might be some memory temporarily wasted which causes it to go over.
