/etc/rc.d/nfsd restart

Yes, that should work just fine for you.  You may also want to mount the 
filesystem being shared via NFS on the server with the 'noatime' option.

Should be no problem then.  So far, I have had great performance with 
the 5-STABLE branch and 6- branch of FreeBSD for NFS serving.  For an 
IMAP mail store, FreeBSD's near-out-of-box configuration (with the 
tweaks we've already talked about) should work wonders.
