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


Perhaps your server's connection smtpd(8) process limit is exhausted
from time to time, but Google's email should get through eventually,
unless there is a systemic network level issue.

Such as, IP or TCP-level options that are not or mis-implemented.


well the interesting thing is that it is SOME not all gmail and mindspring users

for example my gmail account, while slow, get through

am I to tell potential business.. "I can provide mail service for MOST of your contacts??"
