Cyrus does a reverse DNS lookup to log the user's domain name to syslog. This adds an overhead to each incoming connection that increases the number of simultaneous connections to the system and (in larger installations) may become devastating if there is a problem in external DNS connectivity, which may include internet DNS servers that the admin does not control.

This patch adds a "disablereverselookups" option to imapd.conf that disables reverse lookups in pop3d and imapd.
