Hello Marek, I did check if this works. However it seems to not work for me (or I'm missing a setting). Maybe an example for what I want to do helps. Mail is sent to m...@mynoc.eu and forwarder to m...@streamservice.nl. In that case I want the mail from to be m...@mynoc.eu, I don't care about the original address in the mail from during the SMTP stage. Every other location where the original mail address is listed doesn't have to be changed (eg in the mail headers including the "From" line). Kind regards, Mark Scholten
