X-Authentication-Warning: nork: Unknown UID 1071880 set sender to info@domain.tld using -fThe previous entry also is a bit strange ("unknown UID", a German domain although the message was both sent from and addressed within the Netherlands [sorry, the ISP is German...]).
Exactly the same thing happens when I use setHeader("Sender", "info@domain.tld") instead of setSender (and/or the same for Return-Path).
(Note that I edited the e-mail addresses in the above code example. In reality I used existing addresses.)
[EDIT]
I am aware that this is unlikely to be a Swiftmailer problem. But having studied the header structures to a much larger extent than I ever did, you may be able to just give me a hint...
