Citadel /usr/sbin/sendmail replacement
citmail [-d] [-t] <recipientlist>
DESCRIPTION Citmail is the /usr/sbin/sendmail replacement of the citadel-suite to inject mails into the Citadel system from the commandline and the mailbody from STDIN. It uses the LMTP socket for that. Its 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.
SwitchResult

to: Recipient list to send mail to
