I have a static IP ($6 a month extra...). It doesn't hurt to ask I
guess. It's a local isp, they ought to be a bit more flexible. I can
however send out email, just not receive.

I used xs4all back in NL, they're good imo. Though I never tried if they
blocked port 25 I would assume they don't, they gave a free static IP.
Sadly I have no root access to a box in NL. Or anywhere where it'd be
decent to configure an MTA for my home setup.

How to check this? I checked to see if port 25 is blocked by just
running nmap and check if indeed the port was open. Trying various
services configured to port 25 (including smtp of course). It would just
show up as blocked. I guess using syn stealth scan on nmap would reveal
if inbound syn is being filtered.

I have little experience with ssh port forwarding, how would I go about
doing that?
