Not all gmail email coming through exchange

[-Jim]

It seems not all emails being sent from gmail to my company are getting to the recipients. Now this is a tough one because some are and some aren't. Even from the same person. One email sent at 8:44PM will go through,but the next one sent at 8:46PM gets a delay message.

 

Here is an example. I have a user here who uses gmail and on Friday, she sent 2 emails to someone here in the office who is behind an exhange server. The first email she sent, at 8:44PM got through with no delay. The second email she sent, at 8:46PM got delayed and has yet to make it through.

 

I used ESM to try to search for the missing email but it found nothing. Here is the delay message she got in her gmail account:

Looks like the connection timed out, this could be because of a connectivity issue between gmail and your exchange box or the exchange box being overloaded and hanging half way through delivery. I would look at your exchange boxes link to the internet and also check out the software in the way of connectivity that is most likely to be unstable such as a spam filter or some stateful firewall software.

Could also find you're on a RBL somewhere and they're just banning you....
