Use mailman. It sets the envelope sender, meaning that there is no
need for SRS, and presumably supports From: header munging, to work
around DMARC damage.
what damage ?, atleast its not needed on postfix maillist
Hi Benny,
These notes from when we used MD to make a workaround for this issue
before Mailman also implemented workarounds might help:
# BLOCK IF FROM YAHOO (AND OTHERS) BECAUSE THEY SET DMARC TOO STRICTLY

# REWRITE THE FROM HEADER AND OTHER FIELDS PER RECOMMENDATION
