554 5.7.1 Reverse DNS mismatch limit - 01:09pm Jul 5, 2022 CDT - Hi Aaron,

This is from the rejection e-mail. Note, it has now changed to, too many bad HELO.
Thanks...

554 5.7.1 Reverse DNS mismatch limit - 01:26pm Jul 5, 2022 CDT - MDaemon 21.5.1

There is one host, Optonline.net that is rejecting e-mail with the error: 554 5.7.1 Reverse DNS mismatch limit. I have run all the e-mail host related tests at mxtoolbox and all tests pass, including Reverse DNS. Anyone ever see this problem before?..

Gmail spoofing notification - 12:29pm Mar 24, 2020 CDT - MDaemon 18.52
Server 2016

I have tested the mailserver using dmarcian and all tests pass for DMARC, SPF, DKIM, yet, when listmembers send a post from gmail they receive a big yellow "possible spoofing" notification when they open their own posts. Does anyone have any experience with this and can suggest action that can resolve this behavior?
Thanks,
mux

Some members of a listserv are saying the group is receiving their posts, but they do not receive a copy of their own posts. Is there a setting that could cause this behavior?

Thank you,
