Fetchmail polls an ISP server that is always congested (we don't own that server and can't fix it). 1 out of every 20 attempts, roughly, results in an
authentication failure response from that server. It's not actually an authentication problem since it works the other 19 out of 20 items, its actually a busy response.
In any case, the net result is that we get 20-30 messages every day that say:
fetchmail authentication failed on ___
followed immediately by:
fetchmail authentication OK on ______
Is there any way to make fetchmail try several times before sending this message? Or to disable it completely for certain servers?
