Last night, it would appear that zen.spamhaus.org started blacklisting
a number of IPs assigned to Spectrum consumers, of which I am one.
When I tried telnetting to port 25 of my mail server and manually
sending a message to one of our virtual mailboxes, I got this error:
554 5.7.1 Service unavailable; Client host [<my-ip-address>] blocked
using zen.spamhaus.org
I tried putting a bunch of /8's that I know to be assigned to
Spectrum, one of which my own IP was definitely within, into
rbl_override. I then ran postmap rbl_override and restarted postfix.
you have put half of the internet into your whitelist. Don't do that.
Viktor posted the correct hint: use authenticated SMTP on alternative ports.
End-users should not use SMTP on port 25.
