Sendmail, Retrieving mail through protocol (25?)

[KARLB]

Hi everyone, bet no-one's sure about the title, so here's my first paragraph to explain.

I have a situation at work, All e-mails are looked at that pass through our e-mail server at work, and the proxy's been set to not allow most (if not practically all) websites that give e-mail for free. Make sense?

Now, i'm all for security, but this really does my head in if i was to send 'personal' e-mails.

So, here's my plan:

1) sending e-mails.
-------------------
Find an ip for a server that i can connect to (port 25). Connect via telnet (unless they run a packet sniffer i should be ok using this method right?) to the server. mail from... rcpt to... data... ctlr.ctlr - Sent.

2) Retrieving e-mails. (*here's the problem)
Using a mail server (maybe the one i sent from) I need to download new messages.
I assume there should be a way similar to the method of connecting? but maybe because it would be a local server? hmmm. I'd like to know if anyone has any ideas?

i'm assuming the proxy will work on the settings of port 80? for http, if this is not the case, please let me know, but in the event, the likelyhood of the address's for the servers being banned are probably quite remote.


Thanks, and if you need any more info, please let me kow.

You could do something similar to your telnet idea only tunnel over ssh. You must have an account at a remote ip with ssh access. Pick ports on the localhost that are not being used, say 10025 and 10143. Then from an xterm type:

ssh -L 10025:remote.host:25 -L 10143:remote.host:143 -l remoteuser remote.host

enter your password for the remote host and the tunnel has been established.

Then direct your outgoing mail to localhost port 10025 and incoming mail to localhost port 10143.
(port 143 above is for IMAP, Change it if you're using POP).

thanks jaa,

will play about with that method, since my post i have subscribed to cyberspace and am using pine at the moment from there.

This should be sufficient i should think.

Thanks!!
