heh, never thought about delete, since i dont delete emails. sorry about that.
(i have about 100,000 emails in ~/.cache/email. qtemail was designed with my hoarding in mind)

ill add it to my todo list. i use qtemail as my only email client on desktop and n9, so i still actively develop it when i get down time from work.
(you would want it to actually delete the emails on the server, right?)
