delay in connecting

[[EMAIL PROTECTED]]

My qmail server seems to hang for about 30 seconds when an outbound smtp
connection is made to it on port 25....  Once the short delay is over, the
server is very quick in sending out the mail.  What could be causing this
hang?  I don't have the server set to do reverse resolution as far as I can
tell....so I don't know what else could cause it.
