RT not sending mail (no recipients)

I have the suggested (minimal) sendmail configuration in RT_SiteConfig.pm:

Set($SendmailPath , “/usr/sbin/sendmail”);
Set($SendmailArguments , “-oi -t”);

I created a ticket, added myself as an AdminCC, and hoped to see some email
from RT. Sendmail works, as the following relevant error messages were obtained
with the command tail /var/log/messages | mail flengyel@gc.cuny.edu.

My fault: $Organization in RT_SiteConfig.pm should have been what the
comments
state it should have been: the DNS domain name of my site; it was set to the

hostname of the rt server instead of the DNS. Now sendmailpipe works as
advertised,
