Thanks for the detailed explanation. One thing to mention is that this
mail server is pushing close to 1 million e-mails a day, and has no
issues with that whatsoever. Both mail servers mount the /home for the
usernames, and everything is stored in Maildir. I'm almost positive
there are no issues with NFS itself, as all other mail works just fine.
Mailman is installed on both mail servers. /usr/lib/mailman is NOT NFS
mounted (meaning its installed on both machines), however I've NFS
mounted the /var/lib/mailman directory, where all the lists and such are.
Now, with that being said, you mentioned that Mailman can be unfriendly
when placed in an NFS environment. How can I test to see that it is an
NFS issue with Mailman?
I'll take a look at those docs and reply back to here. Thanks again.
