I have my laptop set up to work fine with my home mail server from just about anywhere. The only problem is that I have a couple of classes that I use my laptop for which block certain ports for the network. One of those ports is 25. So I'm able to read my mail just fine over IMAP, I just can't send any outgoing mail. I need some way to get around this.
I can set up my MTA to listen to connections on, say 2525, but that is going to be up all the time. I could also set up iptables to forward any connections from port 2525 to port 25, but again, this will stay up all the time, which I don't want. What I'd like is to have a way to send traffic from my end on 2525 (or something else that isn't blocked) and have it go to port 25 on my mail server. What I had in mind, though I admit that I don't know if it's possible, is to establish a regular old SSH connection on port 22, then somehow 'bind' ports 22 and 25 on both ends. So that as far as the school firewall is concerned, I'm using SSH, but I'm actually sending to and from port 25 on each of the machines. Anyone have any suggestions? Or any other alternatives? Preferably, it won't require any modifications to my MUA or MTA setups. (i.e. I won't have to set Evolution to send on port 2525 or some such, nor force exim to listen for connections on port 2525) -- Alex Malinovich Support Free Software, delete your Windows partition TODAY!
