Hello Viktor, i really do not know what to answer to you about your last email.
Anyway, as i understand envelope sender is where a computer are going to respond an email, if needed, and the from header is where people reply emails. If i'm wrong just an explanation will suffice. That said, i'm still wondering - and i do not know if anyone here is able to answer - why Mozilla Thunderbird or Roundcube get rejected when Editing the From address - at least it looks to me the From address and not the envelope sender - but doing through AfterLogic Webmail the Postfix mail.log show a different behavior/flow. I think that could help me to understand what's going on here, in case you know it. Last, i'm just a Web Software Engineer dealing with some Postfix requirements i try to solve/implement as fast as i can. That's why i'm here, looking for "a little help from a friend".
