Follow up...since nobody knows about this strange occurance... The files that I'm seeing on my SD card in the .MAIL folder certainly appear to be associated with the PUSH of mail. I have it set for every five minutes...and sure enough, every five minutes it puts a 2.4kb to 4.6kb file in that folder. After a day or so, it obviously ends up with thousands in there. I have to use "File Manager" to repeatedly go in there and delete them. Does anybody else see this occuring on your phone/SD card?
Anyway to stop this?
PS It also places attachments that I send AND receive in this folder.
