I have five email accounts defined on a hosting service. On my computer in Thunderbird I have my main account on the left side followed by one of the other five. Then comes Local Folders and two more email accounts. I can retrieve email into my personal account and the one above Local Folders. I can't retrieve into the other two accounts. My wife's computer has HER personal account and one of the ones into which I can't retrieve. She can't retrieve into that one either. I have checked details of the definitions of the accounts on the hosting service and in Thunderbird on both of our computers and can't find anything different on the accounts that don't retrieve mail. I have an Android tablet running the K9Mail client and have my personal account and one of the problem accounts defined. I setup the other problem email account there and got complaints about it not being from a trusted site. I went ahead anyway, went to my personal account and sent a message to the new problem account and was able to go to that account and retrieve the message. What am I missing?
