I tried to make this configuration when we redesign our mail service,
but I couldn't make it work. I could configure the first postfix to
resend the mail with LMTP, but I couldn't configure the second to
receive it.
So, finally we have this same configuration but the traffic between the
two postfixs is with SMTP, not LMTP. We have more than 50000 users and
we haven't appreciate any problem at all with the configuration,. We two
load-balanced servers for the SMTP backend and two more for the POP/IMAP
backend.
But if you are really concern about the performance of the
configuration, I think the better solution would be to configure the
SMTP servers to deliver directly the messages (stored in NFS mailboxes)
and the IMAP servers to just serve the mails, not caring about the
delivery (as someone in this thread have already said).
