Ciao! How are you? Problem: I need 2 interfaces, because the fast ISP blocks 25 port, the slower is open. I can telnet with the required interface: telnet -b 192.168.81.20 alt2.gmail-smtp-in.l.google.com <http://alt2.gmail-smtp-in.l.google.com> 25 The wrong is not working root@server:/etc/postfix# telnet -b 192.168.78.20 alt2.gmail-smtp-in.l.google.com <http://alt2.gmail-smtp-in.l.google.com> 25 Trying 74.125.68.27... telnet: Unable to connect to remote host: Connection refused root@server:/etc/postfix# Correct interface w Works: Trying 74.125.68.27...

But try using port 587 and TLS. All of my research suggests this is the resolution and that Gmail has blocked port 25, and requires TLS. Arthur Johnston
