Email bouncing from certain ISPs

If you are sending email from your server, and certian ISPs are bouncing that email, then please change your outgoing mail to route through your ISP [mail.yourISP.com] rather than mail.yourdomain.com, in your email setup.

ISPs are increasingly using blacklists from irresponsible and unaccountable organisations like SPEWS, in an attempt to prevent the amount of spam that is coming through their network. We work hard to get any of our servers that have been listed, removed from such lists, but this is not always a simple and quick process.

But if you find that email is bouncing from certian ISPs, then you must route your outgoing mail [SMTP] through your ISP by changing the mail.yourdomain.com over to mail.yourISP.com. Contact your ISP if you're not sure of the SMTP setting that you should use.
