current setup (as of March 2016)

• mail delivery - getmail via IMAP with maildrop for filtering/filing into local subfolders
• mail reading/writing - mu4e in emacs
• sending - from within emacs using smtpmail (and smtpmail-stream-type 'ssl) to connect to remote smtp server

some notes…

using getmail to deliver mail from remote server[s] to local maildir folders, with maildrop as a way of filing (filtering) messages into subfolders on the local machine.
