Hi folks. I've got server running sweetly but I do still have one issue that's bugging me. I can rx mail but not tx it so... What's the config I should put into the mail client (Thunderbird) so that will actually connect and send. Oh yes... I installed according to Falko's "perfect Server" tutorial, which I followed very precisely. And the server is the current 10.x.x LTS version. Thanks, Simon.
