mail server services, manually start dovecot, then restart the mail server services and everything goes merrily on its way. Stopping the mail server services drops rpc.statd from using port 993(according to netstat -tlnp). This allows dovecot to take it by default. How to I reserve imap and imaps ports exclusively for use by dovecot. The imap and imaps ports are listed in /etc/services. Thanks for any insight.
The question is not how to "reserve" port 993 -- but how to make rpc.statd (or most of the NFS stack for that matter) behave nicely, and use a dedicated, fixed port instead of a random one. Since you are ending up with the same port always, it is likely that this has been configured to work that way. Not that 993 would be a sane choice, though...
I once documented how to pin down NFS ports, though for a different reason. ;) However, it should help you to adjust the port in your case, too. See the AllowNFS action and documentation here: http://lists.shorewall.net/~kb/
Please note, that this particular documentation applies to "RH style" distros only (including Fedora and Mandriva). It's slightly different for Debian. And impossible for SuSE out-of-the-box, given their braindead [1] init scripts.

[1] Yes, that is a technical term. ;)
