pop3c stops fetching (some) mails

[PrismaComputer]

Bill did a change to an experimental build to address this problem.
Reported here:

But as far as I can remember this is reported from others too. Including me:

But it seems the code never did it to a stable release. At the moment we have to restart the server at night. After restart all missing mails are fetched

We fetch mail every minute and YES we know the recommendation is another and YES, we have to do it once the minute, and NO, we're not talking about 100+ accounts, only 6 accounts are fetching mails from external. I think this should be possible for a modern hard-/software.

Would this problem be addressed by #93 ?
