I don’t know if this will help…I have spent hours today on the phone with my ISP. My email is the same as Lito’s. I can receive but I can’t send. We figured it was firewall related and tried a bunch of config’s there with nothing good resulting. Finally we disabled the outlook AND the mail access scanners on AVAST and the mail is flowing through both inbound and outbound without any issues. my mail died yesterday after I downloaded the update of AVAST (vers 4.5.523) and I didn’t even click to the fact that my mail stopped then. I would have to suspect that there is a conflict in AVAST’s newest software and the SMTP connections? I tried about 5 other email clients today without any luck. I can’t believe that there is a flaw in AVAST personally, because I have been running it without incident forever and can’t think of any better product on the market!!!

Hope that helps
