Thanks for your help Michael. After 3 days of failures every hour or so, we've now gone 5 hours without a blip. Maybe gmail fixed something on their end.
I'll keep your suggestions on hand, in case the problem comes back. Steve Steve Hart Network Administrator 503.491.4343 -Direct | 503.492.8160 - Fax ________________________________ From: Michael B.

But I think they were. On the Send-Connector, set the ConnectionInactivityTimeout to something like 2 minutes and SmtpMaxMessagesPerConnection to something like 5. Did you create a custom Send-Connector like I suggested? If so, also set UseExternalDNSServersEnabled to $true.

I'm not getting reports of issues from any of my clients. I would probably create send-connector just for gmail and set the logging on the connector to verbose and then examine some of the SMTP logs. From: Steve Hart [mailto:sh...@wrightbg.com] Sent: Wednesday, March 13, 2013 12:35 PM To: MS-Exchange Admin Issues Subject: OT: GMail sending woes We're on Exchange 2007. Our emails to non-gmail servers are moving normally. I'm having difficulty consistently sending emails to gmail. Emails move normally for an hour or two. Then, the emails build in the queue. The queue is in the "active" state and there are no error messages. After 5 to 15 minutes, all of the email will move. When I telnet to the gmail servers, I get syntax errors (no matter if the emails are currently going through or not) It's possible that gmail is throttling our emails. How can I troubleshoot this?
