Working hard on the Outgoing Folder. Turns out this is a tougher nut to crack than I have initially thought - the fact that the server may or may not place the email sent via SMTP into the IMAP Sent folder means that Iris has to upload the email to Drafts 1st, transport the mail via SMTP next and then poll the IMAP sent folder to check if the email has materialized over there or not, eventually moving the email from Drafts to Sent in case the server did not do that....

Two more weeks I guess :)
