Having qpsmtpd listen on an additional control port creates serious complexity when running multiple copies of qpsmtpd, as each copy has to somehow figure out which control port to use, hope it's free and then connect.
I usually just strip this code out of qpsmtpd or comment out the initial connection. A great feature to add is a simple command line option to turn this off. Thanks. -- Love feeling your best ever, all day, every day? Click http://RadicalHealth.com for the easy way!
