I guess I didn’t understand that by “use their outgoing mail server”, you meant to change the mail client to SMTP over port 465.

Gmail is supposed to either use port 465 or port 25, but I’m guessing they have port 465 for this exact issue.

Thanks for adding this as another option…

Gmail servers use port 465 for outgoing mail, not port 25. This means that ISP block on port 25 would not affect using gmail server to send mail.

Thanks –
Good idea Brian, but actually, if someone is a victim of their ISP blocking port 25, then using Gmail servers changes nothing, and they’re still blocked.

Another easy fix is to go to gmail.com and setup an account, and then use their outgoing mail servers for sending email in your mail client.

You’re right Jeremy, it’s VERY easy. Almost as telling all of your support people that you’re now blocking port 25, so they can fix it when people call!

I think you’ll soon find, if you haven’t already with your ISP, that if you want to send mail from yourdomain.com but through your ISP’s mail servers is no longer possible, and using other ports is all you can do.

The reason port 25 gets blocked along with a lot of other common ports (80 is a prime example) is it’s VERY easy to setup a mail server in you house that spams email, blocking port 25 makes it more difficult to accomplish this. Usually you just route smtp (outgoing mail) traffic through ur ISP’s server. this will work with any alternate email you may have.

There is a useful discussion of this at http://flyertalk.com/forum/showthread.php?t=793397, a forum of frequent travelers who often have this problem.

Minca, thanks for commenting –

What you claim may be so, about the intended port use, however, checking the SSL box will then not work for users unless their host is requiring them to use SSL, which in most cases, they’re not.

I never claimed this made sense – only that it works –

This port is intended for SSL connection so you have to check SSL button.
