I've been using K-9 since I got my Incredible and I love it. However it doesn't update my Comcast.net e-mail even though I have it on a 5-minute polling... any ideas?
What version are you using? Is it sending emails thru your comcast account or just not receiving?
I had a similar problem initially when trying to get my charter email. Ended up I needed a different port. Went to the charter website and used port 587. Worked perfectly after that.
Glad to hear its working now. Another note, make sure you are using the latest version. Most current now available thru the K9 website is 2.706
This update is not available thru the android market.
