@ms I totally agree! My intention was running the mailserver on a second machine running ipfire! Ich chose ipfire because so I only have to get used to one linux distribution!
My first test was getting mail with fetchmail and giving them to cyrus (both from the pakfire repository) but I couldn’t figure out how to do this! Sending would be done by the clients directly with the mailserver from my homepage provider.
I hope that was understandable, english is not my native language
