I have several small, closed mailing lists running on
SurgeMail. A new list member has a YAHOO address, and the mail
he sends gets rejected by Gmail, Hotmail, Yahoo, and others with
this error message:
Site gmail.com (173.194.74.27) said after data sent: 550 5.7.1 initiative. rc7si2769636igc.23 - gsmtp 550-5.7.1 Unauthenticated email from yahoo.ca is not accepted due to domain's\n550-5.7.1 DMARC policy. Please contact administrator of yahoo.ca domain if this\n550-5.7.1 was a legitimate mail. Please visit\n550-5.7.1 https://support.google.com/mail/answer/2451690 to learn about DMARC
I suspect that the sender's FROM address is triggering this
false positive, even though:
1) The return path is set to Return-Path: <servicename-bounce@eton.ca>
2) The reply-to is set to Reply-To: servicename@eton.ca
3) The sender was verified by SPF "Received-SPF: pass (Last
token {ptr:yahoo.com} (res=PASS)) client-ip=98.xxx.xxx.173; " so
they were a real Yahoo customer.
Is there any way around this? Or do I need to strip out the
sender info in DLIST which makes it harder for users to see who
originated the message to the list?
Note that my current setup has worked for ALL users for years.
This is our first "yahoo" list member.
