Problem sending email with Tripwire

["Aaron Pedersen" <APedersen Interelate com>]

I have tripwire-2.3.1-10 installed on RH 7.3 and have tested the email functionality in Tripwire by running "/usr/sbin/tripwire --test --email johndoe isp com". The problem I am having is when an integrity check ("/usr/sbin/tripwire --check") runs and finds a violation it does not send an email to the name the rule indicates. No email is sent at all?  Any suggestions?  Below is the test case rule from my policy file.

SEC_CRIT      = $(IgnoreNone)-SHa ;
(
  rulename = "TEST ERROR",
  severity  = $(SIG_HI),
  emailto   = johndoe isp com
)
{
	  /home/Doe/Test.txt ->		$(SEC_CRIT);

}

Thanks,
AP
