Even more patience required] Hope I'm not completely wearing out my welcome with the gurus on this list..... I'll be finding my self between a rock and a hard spot in a few days. Anyone who followed the thread about smtp authentication may recall, that my current ISP is having trouble with a bank of phones and the machine that runs them, that stand between my home hookup and the ISPs own hardware. Near as I understand the problem... and only partial at best, is that the machine that relays the dialup accounts to the home hardward including the ISPs smtp server, does something untoward in the protocol which causes the smtp server, or any smtp server to disallow a connection from that machine. This seems to be born out by my telnet sessions. When dialed up to my ISP I cannot telnet to their smtp server nor can I telnet to another server I have on newsguy.com. However I can telnet to either one successfully when on a DSL line that is also on the same ISP but in the same city. That is, when I'm not using the problem phone bank. All this wouldn't be much of a problem except that my stay at the remote address is now over, so I am homeward bound where I will only have the problem connection. I'm not eager to just switch ISPs, especially since they tell me this is a temporary problem until they sack the outfit they are pardnered with and get a new one. Possibly two wk or so duration. This ISP has been friendly and have allowed me shell access... an IMAP server, etc that isn't really that common with ISPs in my experience. I really appreciate being able to ssh into my public_html instead of doing everything with ftp. Further, I will have a DSL connection at the home address soon with this same ISP but no problems with a phone bank. But this won't happen for 3/4 wks. I have dialup access, plus shell access to the ISP machines via telnet and ssh from my home connection.... but not the smtp server port. So I'm wondering if there wouldn't be some way to do business over a ssh tunnel. The ISP is willing to do things like this If I can figure out how it would be done. A few points to consider... I can pull my mail down from their pop server with no problem. I have an individual account on the machine running the smtp server, that I can access via telnet or ssh. > From there I can telnet to any smtp server I want. (having finally learned how to do that here) Or just use shell account tools to handle mail. The thing would be to automate it some how so that dinking around with all the connections wouldn't make it intolerably slow. I don't really understand ssh port forwarding but is it possible to forward the port that my outgoing mail uses to my ISPs smtp port and dump my mail in that way? Or maybe the opposite way round. Ssh to the ISP machine then forward port 25 to my home machine. And aim sendmail at `localhost 25' or something similar.
