Re: Unable to send mail through SMTP servers

I have been struggling for the last 2 MONTHS to send SMTP mail, both from Outlook express, and (forgive the defection) from Mozilla Thunderbird.
In both cases the occasional mail gets through -only if it is REALLY small - 2 or 3 words in the message body. In all other cases I get a message saying that the server has refused the connection.

I initially suspected that it was a mail gateway blocking SMTP traffic that didn't originate in the same network - I understand that this is done to try and prevent spammers from riding on other peoples infrastructure. Understandable.

I set up a POP3 / SMTP account with a small service provider who assured me that my user id and password was authorised to send mail out through the SMTP gateway, irrespective of what network I connected through.

I have now set up a GMAIL mail account and used their SMTP settings, but I still get the same result.

What can be the problem?

Start troubleshooting by disabling the email scanning function in your antivirus program. Email scanning does not provide any additional protection and can cause problems in sending email.
