[Mailman-Users] Mail debug question

[Elvis Fernandes]

Hello,
 I am new to mailman, and having installed mailman on solaris I am testing 
it out now.
 Here is what I am doing:
(1) Test a mail-list.
I created a mail-list unix_sysadmin, and from my mail, I send out a test 
email to unix_sysadmin at hostname
The hostname is the solaris host where I have setup mailman, and my email is 
the only account in the unux_sysadmin list now.
I do not receive this test email.
(2) Tested email from mailman host
I send out a test email from root to my email, and I received that.
 So, what am I missing here?
Is there a way to debug?
 Thanks
Elvis Fernandes
