[Mailman-Users] problem using mailman

[dinar ali kadri]

hi,

i am trying to use mailman after subscribbing to my list if i use my  
local email addresses like dino at pakishop.com or help at pakishop.com. I  
get some smtp-failure error messages  but if i use a different address  
like yahoo then i dont get smtp-failure error but in my error log of  
bounce i can find some queued entries, so may i know what should i do  
to take the advantages of mailman, i am using sendmail as my MTA on  
fedora core 2.

bounce:
Feb 02 07:56:20 2005 (23793) Processing 1 queued bounces
Feb 02 08:11:20 2005 (23793) Processing 1 queued bounces


smtp-failure:

Feb 02 07:42:58 2005 (23797) All recipients refused: {'help- 
owner at pakishop.com': (553, '5.3.0 <help-owner at pakishop.com>... user  
User unknown')}, msgid: <ma$Feb 02 07:42:59 2005 (23797) delivery to  
help-owner at pakishop.com failed with code 553: 5.3.0 <help- 
owner at pakishop.com>... user User unknown

Feb 02 08:07:48 2005 (23797) All recipients refused: {'dino- 
owner at pakishop.com': (553, '5.3.0 <dino-owner at pakishop.com>... user  
User unknown')}, msgid: <ma$Feb 02 08:07:49 2005 (23797) delivery to  
dino-owner at pakishop.com failed with code 553: 5.3.0 <dino-
