I have same issue, but I have found a completely different reason for "double
message sent posts". It turns out that if I choose to save "sent messages"
(that I sent on imap server) to the "Local Sent Items" folder, two things
happen.
1. the message does not get saved to this folder (though it is supposed to
be saved there, and
2. the message registers as being sent twice in the imap "Sent Items"
folder. (it is actually only sent once to recipient; however it shows being
sent twice, as it is registered twice in the imap "Sent Items" folder.
So, what is happening is this: when I elect to save my sent messages to my
Local Sent Items folder (one does this in tools-options-send and then
checking "save copy of sent messages in the 'sent messages' folder), it sends
them twice to the imap server rather than once to imap server and once to
Local "Sent Items" folder.
Does anyone know of a fix for this? Has anyone else experienced this?
