Significant Delays receiving email Exchange 2003 Svr
The follwing issue showed up around 1 week ago... until then everything was working fine.
Simply put, my exchange 2003 server isnt either receiving or processing email in a timely fashion. I have people who are sending emails to valid emails on the exchange server and they are processed almost immediately. At other times the same senders’ emails are not received into the exchange email box for 30 minutes to 4 hours after the email was sent.
I’ve looked at the logs, changed the hardware (DSL modem w/ static IP's) looked at the error reports, ensured my DNS and RDNS is correct - telneted into SMTP on the server a million times- everything checks out. The only thing that DOES NOT make sense is the inconsistency (sp) of when/how the emails are received. Therefore, I unfortunately do not have the consistency of a single point of error and/or I am looking at the wrong place for a solution.
ANY help with this will be much appreciated. I’m not new to SMTP or Exchange, but just can’t get my head out of the forest so to speak.
If you can help, please let me know what information you may need to assist me with this.
Thanks in advance.

Bob, this might sound too easy, but have you tried restarting the Information Store and/or the server?

The delays happen at random times during the day.
The messages are not in the queue. I have noticed that once they get to the queue that are sent immediately to the mailbox.
Yes sir, I disabled the anti-virus and spam filter to make sure.
Vanbarsoun-
Any suggestion at this point is well accepted and very much appreciated.
I did reset the Information Store and the server.
Any other ideas?

Correct me if I am wrong, you are having delays only when receiving emails from external domains? You are able to send
How is the mail flow internally between users?

Yes the only significant issues we are having is receiving emails (intermitently) from outside senders.
There has been some slow down internally, but they are still receiving emails almost immediatly.

Did you test your MX record status?
go to www.mxtoolbox.com and enter your domain name and check the SMTP test and let me know if you see any issues...

mx record status/test checked out just fine...
not blacklisted and the smtp test worked out great.
I was just getting ready to post, but to let you know I have two exchange servers. I changed the receiving server and am still getting the some of the same results with the delayed emails.
I am going to restart the server again tonight along with doing some maintenance (defraging) the IS. I dont think it will make a difference, but - at least ill know that is taken care of. Any other ideas?
Thanks,

Are you receiving directly into Exchange, or is there an upstream mail receiving device?
ASKER
VanBarsoun:
Receiving directly into the exchange server.
Bob
Receiving directly into the exchange server.

This sounds like filesystem antivirus or backup solutions scanning the Exchange directories. I know you've said that you've stopped the antivirus, but it's not clear whether you've stopped Exchange A/V or filesystem A/V or both. Additionally, if there is A/V on another machine performing on-access scan across the network of these directories, they will result in a delay.
Please verify one of the delayed emails in the SMTP logs, to see when it arrived at your server from the Internet vs. when it was delivered to the mailbox in the Message Tracking Logs. You'll need to enable SMTP protocol logging and message tracking in Exchange System Manager of course.

Before I get into your post.... an update.
I moved the SMTP virtual server to the secondary server and that seemed to have been a step in the right direction. All but one of the users (the boss of course) is now getting email in a timely manner (=<15 minutes from time being sent from outside sender).
As for the boss - I would say 90 to 95% of his emails are getting to his email box within a reasonable amount of time. However, the other percentage are still 40 minutes up to 8 hours in delay. Its reasonable (I think) to assume that the initial server may have been the cuplrit (and still may be) as the boss' email box still resides on that server. Not to mention that I tried to run an eseutil /d (this past weekend) on the original mailstore (where the boss' email resides).... got through about 30% of a 12 gig priv.edb and through out a time out error.
So, to your post:
Couple of things, the A/V has been turned off on the Server (for now).... I have been running manual scans (ugh).
Interesting though about the backup question - never thought of that - does BU exec 10.d continually scan the email boxes and stores if they are selected for backup or only when backing up. Reason I ask is that the delay is occuring throughout the day and not at any specific time.
I will turn the smtp logs back on and message tracking in exchange system manager now. I'm not too familiar with the message tracking function... but, will look into it and see if i can figure it out.
Thanks for you assistance.

less then an A because I couldnt find a true issue to the problem just a meriad of hopeful fixes that came down to a network issue. Probably.
During this delay, if you check the message queue, do you find any message there?
Did you try disabling the anti-virus software for testing purposes?
