[Ispman-docs] Postfix LDA delivery

[Wil C. <wc...@na...>]

Both guides by Tony and Jeff recommend for Postfix to deliver to Cyrus:

mailbox_transport=3Dcyrus

I haven't looked at Postfix 2 yet, so maybe it's changed, but on 1.1
that's defined as:

cyrus     unix  -   n   n   -   -   pipe
  flags=3DR user=3Dcyrus argv=3D/usr/cyrus/bin/deliver -e -m ${extension} $=
{user}

Delivering through 'deliver' is ineffecient; for one thing, it entails
invoking another process, but mostly IIRC 'deliver' has to be called
once for each recipient, so you lose the benefits of single instance
store.  What the Cyrus people tend to recommend is using LMTP over UNIX
domain socket:

mailbox_transport =3D lmtp:unix:/var/imap/socket/lmtp
