Mass email | Reply to automatically ads email from instead of using "Reply to"

Examining a received email original (EML) may be helpful.

Hi,

Does it happen always or only with some recipients?

In code, we have only one reply-to address added. Maybe your email server adds the From to the Reply-To. Or it happens on the recipient server.

With just one provider for now, SMTP.com

AWS is ok.

I reached to SMTP.com they said they are not doing it (attached), anyways, thank you for checking yuri , this gives me surety to continue digging with others

Example, I am requesting mass email to send emails from:

info@company.com

and use reply to peter@company.com

Usual behavior is when client clicks reply, it goes to peter@company.com

But with one email address it goes to:
info@company.com, peter@company.com - 2 email addresses


Thanks

Hey guys, I can't figure out, when one group email address is used for mass emails, creates an issue.

When client presses reply to, it has 2 emails, group email + reply to from mass email.

I checked all settings, and they are exactly like others. I can't find the way out.


When I googled, Google AI gave me interesting info:
"In EspoCRM, when replying to a mass email, the "Reply-To" field might automatically include two additional recipients because the system is set up to send replies to the group email address used for the mass campaign, which often includes both the sender and another designated contact within the organization, effectively adding two extra recipients to the reply chain."
But I can't find anywhere original source to be able to figure out how to remove this reply to behavior, I need it to use mass email reply to.

I also checked group email address settings and reply to is empty.

Please help, thanks!
