[rt-users] msmtp and Broken pipe

[Mauricio Tavares]

      Since it seems that ssmtp cannot handle the emails with the
attachments we were sending, I decided to give msmtp a try. So,
I set it up following the wiki at
http://wiki.bestpractical.com/view/msmtp and sent a test email. In
/var/lo/syslog I got:

Why would I be getting a  broken pipe?
