Installation notes: qmail
Due to my el cheapo DSL, i kept getting more and more bounced email because i have a dynamic IP (everydns.net keeps us rockin till the wheels fall off). If your ISP blocks outgoing port 25 (and sbc does block outgoing port 25), you need to send your email through your ISP’s smtp host.
Running qmail? You need to patch it. Go here, download, rebuild, enjoy. Spread the love, as it took me a long while to locate this information.
Also, having just upgraded my plain vanilla qmail installation with the bundle of patches and action from qmailrocks, i can say it is far less painful than installing it manually, but it (can) install a bunch of stuff you i don’t need.
