Fidopoll seems to abort when polling multiple hubs and receives mail on the 1st or 2nd one.
Fidopoll was removed from Mystic I think about 1.5 years ago, so you should be using "mis poll" instead.
If you have any issues with that let me know, but FidoPoll is not supported or guarenteed to work with later versions.
