<div dir="auto">I think the answer is yes, but MailMate can't ask Gmail to do it on MailMate's behalf. MailMate needs to do what Gmail does, which is to contact the "alternate" SMTP servers directly to transmit the mail from a different account. You will need to configure MailMate to have a full account for each sender address.</div><div dir='auto'><br></div>

Remember, the Return-Path: header field is not added by MailMate; it is <br>
added by the receiving system, and uses the address that was in the MAIL <br>
FROM command in SMTP. So you're really asking what determines the MAIL <br>
FROM address in SMTP for MailMate. I can't figure out how to change <br>
that.<br>
