slow authentication challenge from [pop|imap].ge.xfinity.com
I've had pop.ge.xfinity.com and imap.ge.xfinity.com configured as incoming mail servers on local mail clients for years, and use them to check mail several times nearly every day. About a week ago it took over half an hour for each server to respond to initial authentication request. Once authenticated, headers, bodies, attachments as appropriate were transferred at a respectalbe speed. This happened a couple of times in the same day, then not again until today. A little earlier today I had to wait >3 minutes for the authentication response. So I decided to time my next login. While typing this post, the server finally responded to an authentication request I sent 19m53.906s earlier. I think my internet connection is stable and fast. Good luck.
