Citadel /usr/sbin/sendmail replacement
citmail [-d] [-t] (recipient list)
citmail is the /usr/sbin/sendmail replacement of the Citadel Server to inject mails into the Citadel system from the commandline and the mailbody from STDIN. It uses the LMTP socket for that. It's rather simple to enable cron etc. tell you whats going on. If you need a more versatile solution, you should look at for example msmtp.
Switch Result ------ ------ -t to: Recipient list to send mail to -d debug; print whats going on
