Oops, actually it's a really old setting that was somehow missed out, I'll add it to the interface etc on the next build.
But just set it in lists.dat in the mean time.

I cannot find a field on the GUI for "from_list", nor is there any documentation of this feature in:

http://netwinsite.com/surgemail/help/dlist.htm#list_specific_settings

Is this a "secret" feature? ;-)

Ooops, sorry I thought you'd already changed the from, yes you need to set it to be from the list.

from_list true

No there's no nice work around that I know of, they are specifically stopping forged from headers which is what mailing lists traditionally use.

From my tests, setting sender_list true has no effect. The mail is still rejected. I am pretty sure that DMARC only looks at the FROM header.

An online article suggested that removing the DKIM signature from the forwarded mail would solve the problem, but it does not. The mail gets refused as unauthenticated.

It looks like I am reduced to banning Yahoo senders or stripping the sender data and making all the mail appear to come from the list rather than the original senders.

I think the short answer is set:
    sender_list true
to rewrite the sender header.

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.
