G'day Charles,

Looks like the only way is to use iptables as you first suggested. I was
hoping to find method within dovecot or by possibly using tcpwrappers.
On a RHEL/FC system modifying the /etc/sysconfig/iptables file to
include the source (ie -s 192.168.1.0/24) to limit access works, but
then one could no longer use the system-config-securitylevel command to
modify the file.
