fast postfix smtp only

Matteo Cazzador-2
Hi, is it possible to create a fast smtp server only?

This is my scenario:

a customer have 2 sites: "site1" and "site2" , but only one mail server
that reside in "site2", with TLS sasl and all the user defined on it.

The connection of site1 is low.

Is it possible to create a postfix smtp only server that reside on "site1".

My purpose is to "make" sending mail faster from "site1", on mail client
side.

Is it possible to use TLS/sasl with this smtp server (site1) only? Maybe
i need to create a dedicated account?

Related to dns configuration, is it possible to define only PTR record
without MX record for "site1" or is better to make a simple relay on
mail server "site2".

  Thanks a lot.

best regards.

not without seen a slow log of the problem

by default postfix is very fast, so prove you got it slow by showing
logs

and possible aswell postconf -nf, postconf -Mf is not needed yet

Hi, thanks but my problem is not related to tuning, but to slow connections.

If I understand you correctly site1 has a slow internet connection. So
the process of connecting to and sending via site2 is slow. There is no
magic you can apply to fix this - besides increasing the speed of the
connection.

If you setup a relay server on site1, that forwards to site2 - you're
still limited by the connection speed.  And if you setup a "complete"
sending server on site1 - it will still be slow.

Possibly turning off recipient validation would speed up the perceived
mail client operation - but I really wouldn't recommend that.

SMTP MTAs don't have to be inbound MX hosts in order to send outbound
email.  Lots of domains have separate hosts receiving inbound mail
and sending outbound email.
