mails between zmailer in the same networking

[Rocio Alfonso Pita <rozio@universalsupport.com>]

Hello,

I have a problem when I'm trying to send mails between machines with
zmailer (source, target or both). I have the problem too if I put the IP
of the machine, a domain of my internal DNS or an aliases of my hosts
file. For example, if I want to send a email from a machine with
sendmail in the same networking, the error that reports to me is the
following:

PQzc00413#      connection from rs43p ipcnt 1 childs 1 ident:

I don't know what is my error, can you help me? Thanks in advantage.
