Qmail - ISP blocking outgoing port 25 !! HELP

[jingo]

Hi,

My ISP is blocking all outgoing trafic on port 25, except for trafic to their mailserver.
They do this because of spam problems!!

I am running several mail accounts with access from web.
How do configure qmail to send all outgoing mail through my ISP's mailserver?

You will need to configure your qmail server to use a smarthost.

I'm not real sure how to do that off hand, but I think it's truly very easy to do so with qmail.

Basically, you'll point all of your email leaving your server to go directly to the ISP's mail server. That server will then send your mail from your domain. You may have issues if their server doesn't allow you masquerade your domain. But 9 times out of 10, I found this to work just fine.

If you're using earthlink/mindspring, a relay to mail.mindspring.com always worked great for me - they recently locked down port 25 again, so I've had to use that trick - I use postfix, so there's a nice little line in main.cf I uncomment and fill out.

Add the following to the file. Might need to double check my syntax.
