Thanks do Dennis I now got the gif0 interface...

However, I have trouble moving on...

A host 213.88.128.169 is a secondary mailserver for 130.236.218.63.
130.236.218.63 has now been placed in a net where the smtp port is blocked
from the world. I have no access to this firewall.

So how can I make 213.88.128.169 deliver the mail to 130.236.218.63? I
looked at SSH tunneling, but it doesn't seem doable with that. But how
abouts gif?

relayhost# ifconfig gif0 tunnel 213.88.128.169 130.236.218.63

relayhost# ifconfig gif0
gif0: flags=3D8051<UP,POINTOPOINT,RUNNING,MULTICAST> mtu 1280
        tunnel inet 213.88.128.169 --> 130.236.218.63

relayhost# telnet 130.236.218.63 25
Trying 130.236.218.63...
telnet: connect to address 130.236.218.63: No route to host

Uhm... ok, so what am I missing, or did I misunderstand this
completely...?
