Reply w/Email Clients - From: vs. Reply-To:
I'm setting up a new list, and a number of new list members are reporting a problem with replying to the thread. Their email clients seem to ignore the Reply-To: field and instead use from From: field. When they use Reply All, the email is addressed to both the From: and Reply-To:. Reading through previous threads here, I've tried a number of things:
- DMARC mitigation action is "Replace From: with list address"
- For Alter Messages - Set "Reply goes to list"
The goal is that we want a reply to go to the list, not the person posting. Since Reply-To seems to be ignored by some clients, I'm hoping there's a way to force the "From" field to become the list address. Thanks in advance for your suggestions!

Are you saying that a 'reply' , not 'reply-all' will reply to the From: only and ignore Reply-To:? If so, the email clients that are doing that are badly behaved. I can't say they are non-compliant as RFC 5322 <https://www.rfc-editor.org/rfc/rfc5322.html#section-3.6.2> only says:
The originator fields also provide the information required when replying to a message. When the "Reply-To:" field is present, it indicates the address(es) to which the author of the message suggests that replies be sent.
I.e., Reply-To: is only a 'suggestion', but well behaved clients will follow it.
When they use Reply All, the email is addressed to both the From: and Reply-To:.
Reply All should reply to the Reply-To:, To: and Cc: addresses and to From: if there is no Reply-To:. Whether Reply All should include From: if there is a Reply-To is not well defined.

If Alter Messages -> Reply goes to list is set to Reply goes to list, Reply-To: will include the list posting address. What are the clients that ignore this? Complaints should go to the providers of those.
Tf DMARC mitigation action is "Replace From: with list address", that will happen to messages to which DMARC mitigation action applies. If you want it to apply to all messages, set DMARC Mitigate unconditionally to Yes.

That's exactly what I'm saying. And there's more than a few of these badly behaved clients.

Reply All should reply to the Reply-To:, To: and Cc: addresses and to From: if there is no Reply-To:. Whether Reply All should include From: if there is a Reply-To is not well defined.

Complaints sent.

That fixed it. Thanks again, Mark!
