Re: Issues sending to gmail today?



If you run "dig MX gmail.com" from one of your MTAs, what are you getting for output?

Subject: Re: Issues sending to gmail today?

Thanks Jason.  I have some additional information here. 

Also if anyone has any tips to contacting gmail support I would greatly appreciate it.  The only method I could track down requires a google apps account.

Today we got several reports of messages being bounced when our users attempt to send to gmail recipients.  Any assistance you could offer would be greatly appreciated.  We've instructed our user base to try sending again if they get a bounce message like this.  In most cases the second attempt hits either 74.125.142.26 or 74.125.142.27 and delivers successfully.

We're seeing this behavior across a number of MTA hosts in unique clusters that have never had this issue before.  Most messages go through except for those that hit either 74.125.201.109 or, 74.125.201.108

Here's a sample bounce

Subject: Undelivered Mail Returned to Sender

This is the mail system at host XXXX.

I'm sorry to have to inform you that your message could not
be delivered to one or more recipients. It's attached below.

For further assistance, please send mail to postmaster.

If you do so, please include this problem report. You can
delete your own text from the attached returned message.

Hmm, those two IPs are not listed in gmail.com or google.com MX. Does the recipient domain have those two IPs listed? I wonder if there is a STARTTLS requirement on that domain.
