+#+BEGIN_SRC: bash
 editor /etc/default/spamassassin
 #+END_SRC

-
-#+BEGIN_SRC: bash
-set alias_file=~/.mutt-alias
-source ~/.mutt-alias
-set query_command= "abook --mutt-query '%s'"
-macro index,pager A "<pipe-message>abook --add-email-quiet<return>" "add the sender address to abook"

-#+BEGIN_SRC: bash

 For maximum speed and efficiency the recommended email client is Mutt, accessed via ssh, but non-technical people who aren't using an Android app are unlikely to want to use email in that manner.  So it's a good idea to also have a webmail system installed, both for accessibility and as a fallback should ssh not be available due to port blocking.
