My problem: I can receive emails, but cannot send. I receive error message "cannot connect to server, port 25 SMTP". My setup: 2 PCs, both running Win XP Home, OE 6.0 as mail client, both connected through Linksys router, both utilizing Zone Labs internet security suite, ISP is Earthlink. Earthlink blames Linksys. I bypassed router and connected directly through modem. No resolution. Linksys blames Zone Labs. I disabled firewall and antivirus software. No resolution. I have checked account settings in OE 6.0 numerous times w/o resolution. I have serached MS help pages w/o finding answers. Does anyone know how to fix this?
