Since her dialup is listed im Spamhaus, she cannot connect to port 25, since that's forbidden by postscreen. That's about it. Fro: http://www.postfix.org/POSTSCREEN_README.html postscreen(8) should not be used on SMTP ports that receive mail from end-user clients (MUAs). In a typical deployment, postscreen(8) is used on the "port 25" service, while MUA clients submit mail via the submission service (port 587) which normally requires client authentication, or via a "port 25" server that provides no MX service (i.e. a dedicated server that provides submission service on port 25). -- Ralf Hildebrandt Geschäftsbereich IT | Abteilung Netzwerk Charité - Universitätsmedizin Berlin Campus Benjamin Franklin Hindenburgdamm 30 | D-12203 Berlin Tel. +49 30 450 570 155 | Fax: +49 30 450 570 962 ralf.hildebra...@charite.de | http://www.charite.de
