Hello,
I currently host three virtual domains with a postfix instance. Delivery
is, for all accounts, to a (local, using unix socket) dovecot server using
LMTP.
For one of those virtual domains I'd like to have a separate (remote)
dovecot server, while keeping the SMTP (postfix) at the current server.
Thus I'd need something like:
virtual_transport = lmtp:[hostname]:port
(if recipient is in the now-external domain)
(using [] to deliver via lmtp to hostname directly)
virtual_transport = lmtp:unix:private/dovecot-lmtp
(otherwise)
I believe the correct way to do this is defining the default virtual
transport with
virtual_transport = lmtp:unix:private/dovecot-lmtp
and then:
transport_maps = hash:/etc/postfix/virtual_transport
having in /etc/postfix/virtual_transport
external.domain lmtp:[hostname]:port
Q1) does the above make sense?
i.e. will it work as intended (as explained above), so that e.g. if the
(valid, as otherwise rejected) recipient domain is not found in the hash
table then the (default) virtual_transport will be used?
(otherwise, and assuming the above would work, I could just define the
remaining domains also in the table, but I'd prefer keeping it as generic
as possible).
Q2) would it also be possible to -- during a testing period -- have TWO
virtual_transports for a single virtual domain?
This way I could deliver via LMTP to the existing server (via unix socket)
as well as to the new remote server (lmtp via inet).
Thanks a lot in advance for any replies or clarifications!
