I cannot send emails
Posted by Jamie on 18 January 2008 07:19 PM

If you're having trouble sending emails on port 25 (the default SMTP port), try switching your SMTP port to port 26. Most ISPs are blocking port 25 to prevent spam accross the Internet, changing your SMTP port to 26 will solve this problem. The other, probably more convenient nowdays way to send mail is authenticated SMTP on port 465.

If you are using a desktop program you can also try to set the outgoing mail server to your ISPs server. This would be the same outgoing mail server setting that you use for your ISP email address such as ''.
