If you buy a commercial internet account, some ISPs may condescend to allow you to run your own mail servers again, instead of insisting all outgoing mail go through their servers. The way the internet was supposed to work. (This was largely done away with in an ill conceived attempt at spam fighting).
Most large ISPs in the US don't allow ANY listening ports open, and frequently scan for these on consumer plans. Business plans make all that go away.
But in many cases, even with fully valid certificates, you still can't send your own email outgoing, without gong through their (or someone's) smtp server because many mail servers do reverse DNS lookups, and arbitrarily decide that your IP is in a block allocated to consumer use, and refuse connections.
They're rarely arbitrary, but based on publicly available lists/information. Also, if you are intent on running a mailserver, you should make sure you can have proper reverse DNS set up. -- Per Jessen, Zürich (6.8°C) http://www.hostsuisse.com/ - dedicated server rental in Switzerland. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org
