Amos,

Aha!  The vital piece that I was missing!  ;)  I had set local_transport 
and mailbox_transport and even fallback_transport in my attempts to get 
this straight...  So I'm assuming for my local domains I need to just put 
the entry in a transport map for my local domains and it will use the 
single instance message store?  Great!  This should improve things for me!  :)

Hmm...  Made the transport maps for my local domains and set them to 
"lmtp:unix:/var/imap/socket/lmtp" but in imapd.log I'm still seeing this 
pattern:
Feb 11 12:34:52 mailhost lmtpd[16391]: accepted connection
Feb 11 12:34:52 mailhost lmtpd[16391]: lmtp connection preauth'd as postman
Feb 11 12:34:52 mailhost master[12191]: set maximum file descriptors to 256/256
Feb 11 12:34:52 mailhost master[12191]: about to exec /usr/cyrus/bin/lmtpd
Feb 11 12:34:52 mailhost service-lmtpd[12191]: executed

Postfix is reporting the following:
Feb 11 12:34:51 mailhost postfix/lmtp[32424]: D458D1D8056: 
to=<{snip}>,relay=/var/imap/socket/lmtp[/var/imap/socket/lmtp], delay=1, 
status=sent (250 2.1.5 Ok)
Feb 11 12:34:52 mailhost postfix/lmtp[5903]: 9ECD31D8056: 
to=<{snip}>,relay=/var/imap/socket/lmtp[/var/imap/socket/lmtp], delay=0, 
status=sent (250 2.1.5 Ok)

This repeats for each delivery, or so it would seem...  And I'm still not 
sure enough of this to know if it seems to be doing the right thing or 
not...  hehe

Should the master process exec a new lmtpd for each delivery?  This would 
seem somewhat wasteful, especially on a busy system with lots of disk 
IO...  Nothing else is talking lmtp to this server so it should only be 
getting lmtp connections on the socket.

Thanks!

Andy
