24# Description:  Tests basic functions of mail system. The aim of the test is to
25#		make sure that certain basic functionality of mail is expected
26#		to work as per man page. There are 4 - 5 operations that are
27#		done on a regular basis wrt mail. ie.
28#
29#		   mail sent to an user@domain - received by that user@domain
30#		   mail is sent to nosuchuser@domain - mail delivery failure
31#		   mail is sent to user@nosuchdomain - mail delivery failure
32#		   mail to user1@domain and cc user2@domain - mail rec by both
33#		   mail to user1@domain and bcc user2@domain - mail rec by both
34#
