Hi, I installed qmail and vpopmail on a Suse linuxbox, and I added a domain 'test.it' and a user 'utente'. I made a corresponding account 'utente' on an Outlook Express client, and I added its IP address in ~vpopmail/etc/tcp.smtp to allow relaying from that IP. but when I tried to send a mail to a user in another domain (not belonging to this server), the server rejected the message because the domain "isn't in my list of allowed rcpthosts (#5.7.1)". Someone can tell me why? Another problem: ~vpopmail/etc/tcp.smtp allows relay from selected IP addresses, not from a selected user '[EMAIL PROTECTED]'. If I travel with a laptop and I must change its IP address, I cannot connect to my mailserver with my account on the Outlook Express client. Maybe I must configure the server adding all possible IP addresses in ~vpopmail/etc/tcp.smtp? Thanks in advance Franco Vecchiato
