All, FreeBSD 11.2 Running postfix 3.3.2_1,1 I'm getting hammered with thousands of emails from yahoo.com - Here is an example - Jan 20 22:09:01 ns postfix/smtp[1308]: 2DA97A2E2EF: to=<pwascak@aol.com>, relay=mx-aol.mail.gm0.yahoodns.net[98.137.157.43]:25, delay=13730, delays=13728/0.31/1.1/0.06, dsn=4.7.0, status=deferred (host mx-aol.mail.gm0.yahoodns.net[98.137.157.43] said: 421 4.7.0 [TSS04] Messages from 23.24.207.145 temporarily deferred due to user complaints - 4.16.55.1; see https://help.yahoo.com/kb/postmaster/SLN3434.html (in reply to MAIL FROM command)) I'm trying to determine if I am somehow relaying emails to yahoo.com, or is this someone attacking me. I am pretty sure I have postfix to avoid acting like a relay for unauthenticated connections. But this maybe something I have messed up. This has been happening only since I upgraded to 11.2 (I was at 9.x). I also just recently switch from sendmail to postfix as well. I can provide my postfix config on request if needed. Pointers to other mail-lists are welcomed. I decided to start here before jumping on the postfix mailing list. Thanks in advance, Patrick
