Salut Cédric,

Uh. That would be a logic bug. I won't have time immediately, so I'd 
better file an issue in Gitlab so I don't forget.

What's the fetchmail version you're using this with?

You can use the "via" keyword in your rcfile to override fetchmail's 
idea of where to connect, so you could write "poll hermes.example.org 
via 10.2.3.5..." or similar.

Hope that helps,
Matthias
