Is port 25 now being filtered within the tunnel network ? Submission (587), ssh (22) and http (80) appear to be OK (Internet -> 44 net)

No.

OK, thanks ... it may very well be my ISP, I wasn't expecting it on the tunneled traffic though.

It's unlikely to be an ISP, as most of them don't do deep packet inspection on IPIP traffic. I know I haven't added it to the filter list, and a telnet n1uro.ampr.org 25 gets a connection, so as far as I can see it's still working. - Brian

It turned out to be an outgoing filter on port 25 by Shaw ... they are trying to reduce the traffic from hacked machines turned into spambots. Whenever I tested port 25 from a machine on a Shaw network it failed but was OK once I got out to UBC. Access to the Shaw mail server is still allowed on port 25.
