Website contact forms also need to use the reply-to instead of from address when sending email to the site owner. The from address is the site, but the reply-to is set to the contact form user's address so that a simply reply ends up in the correct location. ___ mailop mailing list mailop@mailop.org https://chilli.nosignal.org/cgi-bin/mailman/listinfo/mailop

Is it a problem, if so, where? If it is a problem, are there requirements so that legitimate email is accepted? I would argue against filtering based on discrepancies against the 5322.From and 5322.Reply-To headers. I used to advise customers to have website contact us forms send the mail with a 5322.From email address they controlled with the 5322.Reply-To being the purported address as provided by the person filling out the form. - This allowed the contact us forms to safely send emails without violating any hygiene tests (at the time). - I believe the same methodology would work now with SPF / DKIM / DMARC. -- Grant. . . . unix || die smime.p7s Description: S/MIME Cryptographic Signature ___ mailop mailing list mailop@mailop.org https://chilli.nosignal.org/cgi-bin/mailman/listinfo/mailop
Re: [mailop] Different From domain and Reply-To domain
Where I see freemail addresses in the reply-to in valid mail is in various mailing list platforms, ones that work around DMARC blocking by rewriting the from, then moving the original poster's email address to the reply-to, to allow for off-list replies. Not so much that I'm looking to argue whether or not this is valid or really common or should be allowed, just saying that I see it today. :) On Thu, Dec 7, 2017 at 10:17 AM, Ken O'Driscollwrote: > On Thu, 2017-12-07 at 14:50 +0100, David Hofstee wrote: >> Hi, >> >> Can people here share their experience (or spamfilter configuration) with >> differing 5322.From and 5322.Reply-To domains in larger volumes of >> email? > > Completely agree with Vladimir and Al, it's common practice. > > The only exception I can think of, is if the reply-to was a freemail > address.

Completely agree with Vladimir and Al, it's common practice. The only exception I can think of, is if the reply-to was a freemail address. And, even then, you couldn't 100% assume the mail is bad because legitimate users can use email in strange ways.

Re: [mailop] Different From domain and Reply-To domain
Yeah, lots of ESPs, list management tools, and ticketing systems can be and often are configured to use a different reply-to address, sometimes in a totally different domain. We have a fair number of clients who do this today and they don't experience any deliverability or filtering issues that we would attribute to having a different reply-to. If you were to start filtering based on that, you'd be an outlier.

Re: [mailop] Different From domain and Reply-To domain
You should never do it, having different e-mails in From: and Reply-To, including ones from different domains, is a common practice. E.g., mailing lists like this can change From or Reply-To, most probably the message you read right now has From and Reply-To from different domains. 07.12.2017 16:50, David Hofstee пишет: > Hi, > > Can people here share their experience (or spamfilter > configuration) with differing 5322.From and 5322.Reply-To domains in > larger volumes of email?

[mailop] Different From domain and Reply-To domain
Hi, Can people here share their experience (or spamfilter configuration) with differing 5322.From and 5322.Reply-To domains in larger volumes of email? Is it a problem, if so, where? If it is a problem, are there requirements so that legitimate email is accepted? Any info and opinions on this is appreciated. Obviously, my customer is owner of the two domains. His customer care is done by a holding company. One can say there is a legitimate reason. I'm just looking if this is a possible cause of problems, or not.
