I have a 2 Mailbox servers(exchange2010)  DAG environment. Server1 and Server2 and database is mounted/activated in server2 is always.  One week before I noticed that internal emails are receiving slow.
I activated/mounted the server on server1 and all emails flowing fast. After restarting I activated again server2 few days back the same persists.

Is there anyone who faced the same issue.

Backpressure:
 
Backpressure issues account to most of the email queue building issues. In simple words, backpressure means exchange is unable to process emails due to resource bottleneck issues.
 
Backpressure events look like this:
 
Log Name: Application
 Source: MSExchangeTransport
 Date: 4/17/2013 7:00:34 AM
 Event ID: 15004
 Task Category: ResourceManager
 Level: Warning
 Keywords: Classic
 User: N/A
 Computer: HUBServerName
 Description:
 Resource pressure increased from Normal to Medium.
 
Resource utilization of the following resources exceed the normal level:
 Version buckets = 123 [Medium] [Normal=80 Medium=120 High=200]
 
Back pressure caused the following components to be disabled:
 Inbound mail submission from the Internet
 Mail submission from the Pickup directory
 Mail submission from the Replay directory
 Mail delivery to remote domains
 
The following resources are in the normal state:
 Queue database and disk space (“Q:\Program Files\Microsoft\Exchange Server\TransportRoles\data\Queue\mail.que”) = 3% [Normal] [Normal=95% Medium=97% High=99%]
 Queue database logging disk space (“Q:\Program Files\Microsoft\Exchange Server\TransportRoles\data\Queue\”) = 4% [Normal] [Normal=95% Medium=97% High=99%]
 Private bytes = 16% [Normal] [Normal=71% Medium=73% High=75%]
 Physical memory load = 40% [limit is 94% before message dehydration occurs.]
 
So, make sure that there are no 1500x events listed in the application logs of the event logs.
 
The following links are good resource for troubleshooting-

Thanks for your suggestions I am checking that now.
But I was thinking both servers are identical with Windows2008R2 and Exchange2010SP2.
How come only one server is having email delay?

Are they resides in same Data Center / Site?

Any Disk I/O on that server?

How many CAS/HUB servers do you have? does that problematic MBX server connects properly with CAS/HUB servers?

Take a look at the message header, it will tell you where the mail was stuck / delayed.

It is in the same site.
I have only 2 MBX server and HUB/CAS servers.
HUB/CAS in the same server hardware of MBX

i.e. 2 hardwares with all 3 roles installed in the same OS

Still sometimes the secondary server shows "timedout" when it is idle.

Any idea?
