Your configuring a system at dydns.org or some other mail forwarder to receive your mail for you then forward it on to your system using the alternative port. You can just as easily set up a mailbox on the dydns server (or whoever will sell you a mailbox - tons of ISPs will do it) and fetchmail your mail via POP3 from it. > Install ddclient on your machine; it will keep your IP updated at > dyndns. > > Install an mta, like sendmail, and smart-host it to your ISP; or > smart-host it to dyndns if your ISP can't/won't do it. > > I have been doing this for about 2 years now, and have had no problems > at all. > I'm sure you don't because in effect your doing exactly the same thing that any typical e-mail client does - your offloading the heavy lifting of receiving mail - the spam and antivirus filtering - to a real mailserver somewhere on the Internet. Frankly, unless you processing mail for a lot of people, there is no benefit to running your own mailserver, and you really ought to be using a client-server model for getting mail, as you are doing. The OP just hasn't realized this yet. Ted
