from and to are swaped

It's actually a feature that MailMate automatically creates a follow-up message when replying to a message written by yourself.

If I understand you correctly then you play two roles and need to:

• Send as role 1.
• Send as role 2.
• Reply to a message sent from role 1 to role 2.

If MailMate knows both role 1 and 2 then I think this should already work. If MailMate detects that you are both sender and receiver then it should not generate a follow-up message (it works this way because I often send test-messages to myself).

So, I've either misunderstood what you are trying to do or there is some other problem. Does MailMate know that both email addresses are yours?

Ahh, I see ... this is the background, thanks for explaining! Well, you are right this is a feature, as long as you are not using role-accounts. The present situation, where it makes troubles is, if you are having the sending address of the e-mail you want to reply to in your list of sources. Somehow MailMate does not detect that situation. I'll attach an other more detailed commented screenshot.

Also interesting and may be the source of this problem: If someone sends an E-Mail to two recipients, and both of them are configured as source in MailMate, the question arises, who is the sender in case of a reply. At the moment the alphabetically first source is chosen (I guess).

I suggest, that offline-sources should not be chosen as sender (at least not automatically) - that may solve the whole problem. What do you think?

Attached three screenshots, which illustrate the status quo. booking@ is the Booking-Account (offline)-source and welcome@ is the Business Apartment-source.
