Did you install it on all of them, or just one?  When you say they 
share a common NFS point, are you trying to use NFS for the postfix 
mail queue (which is a really, really bad idea), or just for the user 
mailboxes (which is also usually a bad idea, although it can be made 
somewhat less bad if you choose a mailbox format that is less 
NFS-unfriendly)?

Mailman itself is about as NFS-friendly as can be reasonably done, 
but that still leaves a lot of room for problems.  Many of the other 
parts of most mail systems are much, much less NFS-friendly than 
Mailman.

When troubleshooting Mailman, you generally want to start with the 
steps outlined in FAQ 4.78 at 
<http://www.python.org/cgi-bin/faqw-mm.py?req=show&file=faq04.078.htp>. 
You should also search the FAQ Wizard for other things that might be 
related to your problems, and you should also search the archives.

If NFS is involved anywhere in the picture, odds of Mr. Murphy 
raising his nasty head have been increased by many, many orders of 
magnitude.

That said, there are occasionally times when such a system has 
problems that are actually unrelated to NFS.
