I don't think they are the same thing.
AFAIK an ssh tunnel would require ssh on both sides.

I don't think so, but this is not what you asked in the first place.

What both Marco and I suggested is:
_ local stunnel that listen on local x.y.z.w:25 and forwards the 
connection (encrypted) to smtp.1blu.de:465;
_ sendmail configured to send to x.y.z.w:25.

Of course x.y.z.w cannot be 127.0.0.1 if sendmail is already listening 
there.

HTH.
