I cannot send e-mail

If you're having trouble sending emails on port 25 (the default SMTP port), try switching your SMTP port to 587. Most ISPs are blocking port 25 to prevent spam across the Internet, Changing your SMTP port to 587 will likely resolve this problem. If this does not work, we suggest trying port 26 instead.
