I'm not trying to host here (in this case). My mailserver is at a hosting provider, where all is good (barring the lack of IPv6 ...).
It's when my home machine connects to my mailserver that I see what I thought was considered a misconfiguration of DNS.
I'd argue that a mail server is misconfigured if it logs a warning when an authenticated client submitting mail on tcp/587 doesn't have matching forward and reverse DNS.
Point taken. Unnecessary, at least; not sure about misconfigured. I'll probably change it.
Mail submission != mail transfer, and DNS records the client does or does not have are not all that relevant for mail submission.
I see it from a client's server that sends me mail too - but then I set it up ... and it should probably be sending via a relay. Richard
