I am getting these alerts frequently and am concerned with them. What should and can I look at to track down the cause of this daily?

Information Store Queue of Messages from MTA > 25   This rule tracks the number of messages in transit from the MTA to the Exchange store. It uses the MSExchangeIS Transport Driver object and the Current Message From MSExchangeMTA counter.

I read the technet, but it does not really say, "check this out and if this is not working, then this is the reason why"

Severity:  Error
Status:  New
Source:  MSExchangeIS Mailbox:  Send Queue Size:  _Total
Name:  Mailbox Store: Send Queue > 25
Description:  MSExchangeIS Mailbox:  Send Queue Size:  _Total value = 25.2. The average over last 15 samples is 25.2.
Domain:  MYDOMAIN

Please download and run the Exchange 2003 Best Practices Analyzer tool and see what that produces:

Have you looked at the queues?  If so, who is the mail from?  Is it internal people, people you have never heard of or is it the postmaster?
You could be an open relay, authenticated relay, or sending out backscatter (replying with NDR reports to spammers with spoofed email addresses).

Are you getting events 2020 & 2019 in the Application Event Log too?
If you have - it sounds like your drivers are not up-to-date.

Probably worth a quick server reboot, then make sure your drivers are all up-to-date, Windows is up-to-date and Exchange is up-to-date.

Are your AD admin tools letting you down?

Managing Active Directory can get complicated.  Often, the native tools for managing AD are just not up to the task.  The largest Active Directory installations in the world have relied on one tool to manage their day-to-day administration tasks: Hyena. Start your trial today.

we will fail the cluster over late. no 2020 or 2019 events. but the nic drivers are over 3 years old. we will take care of that later, but still wondering what is going on now.

Sounds like a memory leak - which needs to be identified and resolved.
Please keep me posted on your progress after failing the cluster.
Thanks
Alan
