''''''I already wrote but should say I'm on MAC not pc...'''''' I recently changed all my pop to imap.. It's been a disaster...I was not able to send or receive from any of my 3 computers after the change. It took me days of all my possible help "passing the buck" "not our end": a)my spam protection people, b)internet provider c)email domain hosts (2 of them- just for fun) And, of course, the no tech support Thunderbird (fun part of the equation).... there is also a password problem somehow which I bypassed smtp finally using port 25 and 2525 unsecured... and I now can send and receive...WOW. I'm pretty much an expert after a full week of 8-12 hour days... This all happened because I was getting occasional failure to send bounce backs...thought I'd fix it... Anyway current problems are: 1) working with our spam protector tech transitioning from my very happy pop life to imap: ALL my message folders (15 years worth of business email) in one box were deleted.. 2)In my other domain all my message they seem to be there but are greyed out, labeled "IN BOX bla bla..." Is it possible to recover these and how? I've looked in "Profile Folder" "Show in Finder" and some seem to be there... how can I pull out these folders and sub folders that I depend on for my work? Is there anyone to help me??? Thank you.
