[Mailman-Users] Mailing List - people say their e-mails "never appear"

[Patrick M.]

Hi all,

I just installed Mailman on our load balanced Postfix servers.  Both 
servers share a common NFS point.

Please forgive me, as I'm very new to Mailman.  While I know my way 
around Postfix, troubleshooting Mailman is another issue.  I can see 
that e-mail gets sent and delivered to the particular mailing list in 
question, but sometimes people tell me their e-mails never get posted to 
the mailing list.  Other people say they submit their post, and it 
eventually gets there, after 10 or so minutes.

Since I don't know how to troubleshoot Mailman, I can only suspect that 
is has something to do with the NFS, although another part of me is 
telling me that it can't be.

Can you folks push me in the right direction?  What should I be 
troubleshooting?  Is there anything I can provide so that you folks can 
help me troubleshoot further?

Thanks in advance.

Patrick
