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
Please think. Are they connecting from the same machine that can't
send mail to your SMTP server? No.
ahh ok i see your point on that
they can ping my server. so DNS is fine
Think again. Are they pinging from the same machine that can't
send mail to your SMTP server?
I repeat my suggestion that you collect real data to show that
those SMTP packets from gmail actually reach you. Because when
you finally discover that they don't then you can go and fix the
real problem.
i have no idea HOW to get that real data.. I do not have access to the
servers that are connecting and none of my logs shwo info on the
failed attempts
