I have installed Request tracker v4.0.8 in CentOS 6.2 system using [this documentation](http :// harbot. me/2012/05/22/how-to-install-request-tracker-4-0-5-in-centos6/).
I'm using msmtp for outgoing email. msmtp works in command line and I get email. But when a ticket is created in RT, it doesn't send mail.
Here is the /var/log/messages:
Tmailer: CALL /usr/local/bin/msmtp -nt -oi -t RETURNED 74 Dec 24 16:21:39 RT RT: <rt-4.0.8-8887-1356346299-1411.17-3-0@organization> sent To: user@organization (/usr/local/rt/sbin/../lib/RT/Action/SendEmail.pm:316) Dec 24 16:21:39 RT RT: <rt-4.0.8-8887-1356346299-748.17-4-0@organization> #17/280 - Scrip 4 On Create Notify AdminCcs (/usr/local/rt/sbin/../lib/RT/Action/SendEmail.pm:285) Dec 24 16:21:39 RT RT: <rt-4.0.8-8887-1356346299-748.17-4-0@organization> No recipients found.

What is the error returned 74?
