Re: [MLUG] postfix, imap problem

["Daniel Nowlin" <EMAIL:PROTECTED>]

finally we solved the problem.  It was a reverse dns/ident problem.  His 
router will not let him ping his homeip.net address.  I just told xinetd/pop 
to not do the reverse thing by commenting out the two log_ lines and 
everything works grand.
Thanks for all of the ideas.
