[Mailman-Users] Update: Postfix/Mailman breaks (somewhat) upon sending out to list of 300+ users

[Ted M Harapat]

Okay, I ran xtail on several of the files when I restarted postfix to see if 
that would show many anything. And it did! Here's what I received. 

*** error ***

(repeat above line 257 times, one for each missed mail in the list)


These errors look like they are going to be helpful... unfortunately, not to 
me. Rather only to people who understand them, especially the ones within 
the "error" file. Can anyone help me translate and see whatever I've broken or 
possibly misconfigured?

Thanks.
