I have spent hours and hours configuring my `mutt`, `offlineimap`, `putmail.py`, but I have since grown disenchanted. In my experience, `offlineimap` is annoyingly prone to crashing without any indication. Thus, checking mail within `mutt` becomes unreliable. However, my favorite aspect of `mutt` has been and remains being able to send e-mails very quickly and easily through Terminal.
echo "Hello World!" | mutt -s "Test E-mail" -a "file.txt" whomever@wherever.com
Therefore, I now use `mutt` exclusively for sending mail and using Gmail.com for reading and searching mail.
