Mail forwarding options summary

A collection of mail forwarding options, ranging from simplest satellite systems to normal mail forwarding via exim, qmail, and sendmail, and to the advanced topics like using Postfix to relay email to SMTP server that enforces TLS (eg. nowadays ISP and/or gmail).

If you control satellite systems and you're not expecting to send much mail, and you don't need much processing then running a full mailserver is probably overkill. Perhaps the simplest software to use is the nullmailer program

Setting up mail forwarding for exim, qmail, and sendmail

how to make postfix to use SMTP auth for sending mail to a smarthost or a
transport map relay server.

Gmail on Home Linux Box using Postfix

Having read all above, I am still not able to setup my Postfix to relay my mails through my ISP (with TLS required). I had tried many times but all failed. I've also been trying to raise the question at every possible place. But so far respond answers the question.

I really appreciate if anyone can give me a hint. Thanks a lot.

The reason that I need the mail relay is because my ISP has blocked my 25 mail port. So it is impossible for me to file bug reports, use my mail to backup my save-config, etc ... Now that nearly 90% of people are suffering from this mail port block, this feature would be requested again and again.

I share your pain, I did this once with Postfix, and the documentation doesn't always make it clear what bits are for server to server, and which bits are client server.

In the end I found a short explanation by Patrick, as always I can't find it again, but assume this is what he replaced it with. h_mailservers.html

Has to be said Postfix is a lot easier if you use it as an MTA, and not a mail client ;)

I seem to recall you only need a very small amount of general SASL configuration, and then the client stuff, i.e. when you have it understood there really isn't much to do, it is just the understanding that hurts.
