I have the following situation: gmail polls my university email via pop3, but it does so with a delay(around an hour sometimes). So I set up fetchmail to poll my university email.
It solves the delay issue, but since fetchmail polls gmail as well, so there's two copies of each mail sent to my university address(one from uni, other from gmail(that got it from uni)). Is there a way for fetchmail to recognize duplicate emails and discard them?
