In some email I received from "Abdul Salam" <abdul at netsite.co.uk> on Fri, 21 Feb 2003 10:48:10 -0000, wrote:

80 is http and 23 is telnet, totally irrelevant with the sumbject.
when you`re sending email the connectiong between smtp <-> smtp is a stateful connection, that means you should see something like ESTABLISHED, when a connection is obviously established. TIME_WAIT means it waits certain after the connection is FINinshed, but still the kernel waits for some packets which might be left on the network for this TCP session. That means that your connection was established and manage to finish whatever it was doing.
it`s a "operation timeout" err which doesnt make much sense, i`d say it`s a resolver issue, check your DNS settings, check your /etc/hosts.
hope that brings some light.
can we have the output of host -a smtp.mydomain.co.uk?
also you might as well consider *ad* http://cr.yp.to/qmail.html + http://www.flounder.net/qmail/ + vpopmail, you might as well like it.
i find it more efficient than sendmail, also it`s a very powerful tool when you combine it with sql/ldap/whatsoever, quite robust, simple and stable ;) */ad*
