Jos Chrispijn via Postfix-users <postfix...@cloudzeeland.nl>
is rumored to have said:
Running mailservice with Postfix
PTR record is set to myserver.mydomain.com (1.2.3.4)
Every time I receive external e-mail, my logfile shows:
Apr 25 15:01:39 terra postfix/smtpd[12479]: 073416D2:
client=unknown[1.2.3.4], sasl_method=LOGIN, sasl_username=me
How can I configure that client=unknown[1.2.3.4] will be replaced with
the PTR record text instead?
Make the name in the PTR record resolve back to the same client IP.
I could force that by puting 'myserver.mydomain.com 1.2.3.4' in my
hosts file, but I am not quite convinced that is the only solution.
Actual DNS is also an option, and a better one usually.
As you've chosen to pose this as a hypothetical with bogus details,
there may be complications we can't see.
