You can use [[http://mutt.org|Mutt]] to receive and send email on the HCoop server. However, in order to use Mutt, you have to set it up for working with the [[http://dev.mutt.org/trac/wiki/MuttFaq/Maildir|Maildir]] format; add the following to your `.muttrc`:

{{{
set mbox_type=Maildir
set folder="~/Maildir"
set mask="!^\\.[^.]"
set mbox="~/Maildir"
set record="+.Sent"
set postponed="+.Drafts"
set spoolfile="~/Maildir"
mailboxes `echo -n "+ "; find ~/Maildir -maxdepth 1 -type d -name ".*" -printf "+'%f' "`
macro index c "<change-folder>?<toggle-mailboxes>" "open a different folder"
macro pager c "<change-folder>?<toggle-mailboxes>" "open a different folder"
}}}
