NFS & IMAP... Acting very bad.

[Carlos Escutia Chávez]

I had a similar problem once when I installed qmail. From
qmailrocks.org website:

"Q: 
	I've got my qmail server up and running, but the smtp server is
running extremely slow. What's wrong?
A: 
	This can result from a lot of things, but most often it's the result
of a DNS error of some kind. Check to make sure your mail server's
hostname has a proper DNS setup. You may want to try
www.dnsreport.com. to test your server's DNS configuration. Also, make
sure that your server's IP address has a reverse PTR record associated
with it. Additionally, I would recommend installing djbdns and running
a local caching nameserver to which your qmail server can make fast
queries. You can find help on djbdns at www.djbdnsrocks.org.
"

Hope it helps.
