If you are using the free Cogeco Security Services (their licensed flavour of F-Secure) it is apparently filtering email incorrectly and that is why you are getting the 0x800CCC19 return code from your POP server. I have contacted the support line about this several times and have been told a couple of times to uninstall Cogeco Security Services and reinstall it and "see if that helps". It is a time-waster.
Their main response is to use Cogeco Webmail at this time.
I am exceedingly unhappy with the level of service that Cogeco is giving on this particular problem. Perhaps they should hire a third-party to help them out of their email-hell and give their paying customers a better level of service. I cannot imagine why they cannot simply "dial-back" how aggressively F-Secure is filtering. It has been a couple of weeks now.
Some email showed up this morning and I no longer get error codes this afternoon.
As the biggest computer noob in DSLR history I don't have a clue how to load patches and figure out if I have a 32 or 64 bit processor.
I just mindlessly click on the F-secure boxes to put in a newer version.
