[Mailman-Users] mailman "user unknown"

[Karen R McArthur]

I'm placing mailman into production for the first time - and I have 
approximately 2500 lists.  Many of my lists work fine, but many do not. 
  On them, I receive a "user unknown" error.  An example: when send to 
the "seo" list, sendmail -bv seo at lists.bates.edu returns 
"seo at lists.bates.edu... User unknown"

I have the seo lines in aliases.mailman - and a strings on the 
aliases.mailman.db returns correct data for the list.  Some lists listed 
in aliases.mailman AFTER seo work correctly, as do some lists listed 
BEFORE it - elimination my idea of a corrupt file.

aliases.mailman was generated through "sudo -u mailman bin/genaliases -q 
 > aliases.mailman".
I have run newaliases.
I have restarted mailman.
sendmail.cf includes /etc/aliases.mailman in the ALiasFile line - and is 
working as it should since some of my lists are working.

aliases.mailman is 28,896 lines long - is that a problem?

Any ideas?
