Bug Description
Builds from courier-mta sources prior to 20211111 have two bugs:
1) parsing bug in the bofh badfrom check
2) rejects null MX records when validing the sending IP address against the sender's HELO/EHLO identifier
#2 is causing Yahoo mail with null MX dns records to be rejected. Yahoo is a major player in the email world and this should be considered a priority
Recommend that new .deb binary be generated using courier-mta 20211111 or later.
1) Bionic Beaver
2) courier-
3) expect all mail from Yahoo to be delivered
4) mail with null MX dns records are being rejected
