[mail.kasdivi.com. (5): Connection timed out]

If Google's TCP connections time out, naturally your Postfix server
will
have no record of the connection attempt, and your Postfix
configuration
plays no role in the problem. This is a transport or network layer
issue,
and nothing at the application level will fix it.

For what it's worth, I have no issues connecting:

Same here (from 168.100.189.2).


I, from a philisophical basis, understand,  but the fact remains  I
have several gmail and several mindspring users that can not get
through to my clients
I know those domains for fact.. but have reports of othetr sbut not
enough information to chase them

If you want to solve this, then you will need to do the measurements
that provide the evidence of what is going on.

Until you can show network packets from gmail etc. trying to connect
to your Postfix server, you have no evidence at all that this problem
belongs on this mailing list.



the users can access my web page   so web services are fine

they can ping my server. so DNS is fine

i have the message that says that it can't contact my mail server.. my  
MTA is Postfix where else could iI see help??

do I have to drop postfix and goback tosendmail to debug??
