dear list,
I am using postfix as mail relay which is deployed on gateway for internal
users.
This relay send mail out only, doesn't accept messages.
My question is, do I need to make the relay server port 25 listened on 0.0.0.0?
or just 127.0.0.1 should work?
Thanks

One way is webmail I may think.

how do internal users connect to your mail gateway?

port 25 only need to listen on 127.0.0.1 not the same as loop-back for
all ports in master.cf
Hi All,
We have two customers who we're unable to receive email from.
It's failing the helo lookup as it can't resolve the hostname in the helo
message.
Helo command rejected: Host not found;
The postfix configuration for helo checks is as follows. It's failing on
reject_unknown_helo_hostname

Has anybody come across this before and any idea how to resolve it?
32 ips with one single helo name ?
solution is 32 ips with not a single helo name

The issued hostname is logged just prior to this text.

So I decided to walk before I could run. Getting backup MX with MySQL
backend to restrict to just valid users is proving harder than I thought.
But for the time being, what I did was reset the config on the secondary
MX to a very standard postfix config using hash: and Berkeley DB files.

It’s via HTTP API to post messages to gateway which then relay messages out to
internet.
Thanks.

If none of the mail arrives via SMTP, you don't need to enable an SMTP
listener. Just comment out "smtpd" from your master.cf file.

The parameter smtpd_relay_restrictions was set twice in
main.cf. You should decide which one you want, and
delete the other (or combine what you want into a
single version). The postconf -nf command shown above
would just output the one that Postfix ends up usin
