I was used to use USENET in the 90ties. Does comp.mail.sendmail still
exist?

I've never used stunnel, only SSH and port forwarding. The IP addrs in
question are

for my SSH account:

$ host www.unixarea.de
www.unixarea.de has address 178.254.11.41

for SMTP port 25:

$ host smtp.1blu.de
smtp.1blu.de has address 178.254.4.101

Can I do such stunnel to route SMTP to 178.254.4.101:25 without
involving my ISP before?

I'd even have to compile security/stunnel, but I checked, I can do this
from here in Cuba with my FreeBSD netbook.

Thanks

	matthias
