puts an example.com in my mail return address

Hi there

Using : Debian-60-squeeze-64-LAMP

when a user on the server sends to someone, their reply address is listed like this:

paul.ddha@example.com

But the address should be

paul@ddha.se

can anybody help

best regards
Bison

Please give us more details about how that user sends the email (email software? webmail? Usermin?), and what exactly you mean with “reply address” (Reply-To header? From header?).
