[Mailman-Users] Can Send thru List - Plz Help

[Terry Rossi]

After upgrading to 2.1.1 I cannot seem to send to my list anymore. The
stmp-failure log is full of 

Feb 25 21:32:35 2003 (95755) delivery to xxxxxxxx at pics.com failed with
code 553:  5.1.3 <pics-mail-bounces+xxxxx=pics.com@>... Hostname

with code 553: 5. 1.3 <pics-mail-bouncesttttt=pics.com@>... Hostname

Any help would be most appreciated.


Thanks
