Slow Local Mail delivery

I am having trouble with my MS Exchange 2003 server local delivery. After a while my Local delivery will deliver mail at a crawl, it will slowly empty out some e-mails then grow larger, then deliver a few and grow larger. This seems to get resolved after I restart the Information store and all the messages will quickly get delivered out of the Local deliver folder. But after an hour or so the delivery will slow down again.

Does anyone have an idea of what might be causing this issue?

Thanks
Rob

Which AV solutions are you using ?
Try stopping SMTP and RE services, rename the VS1 folder, recreate the folder structure within it (empty)
Restart SMTP and RE services.

You may want to delete the SMTP Temp tables - however, that can be done later.

After a server reboot, this issue went away for a couple days until now. Where is the VS1 folder located?

I have renamed this folder and recreated the structure but I am still having the same issue. the issue takes a while to appear which is why I havent updated this thread too fast.

Any other suggestions as to why this might be happening?

THank you,
Rob

I have my mailbox store split up into 3 storage groups with about 4 or 5 seperate store in each group.
the databases range in size from 3gb to 32gb, total they are about 200gb

I have had this configuration for a couple years now but didnt come across this problem until reciently.

I am using a Symantec Antivirus client. Symantec Mail security has been installed for a while but has also been disabled since we havent renewed our subscription to it.

The Symantec Mail security? Yes I can, I will need to schedule that uninstallation since it may require a reboot. I will confirm once it is uninstalled.

I removed the Symantec Mail security and bumped the transport diag to max. I will monitor it from here to see if the issue happens again.

Thanks

Great, thanks for performing the troubleshooting step.

"I have my mailbox store split up into 3 storage groups with about 4 or 5 seperate store in each group. the databases range in size from 3gb to 32gb, total they are about 200gb "

Also, could you tell me as to in local delivery queue - are emails being stacked up for any particular store in majority or its equally divided.

No, it seem to be mail going to any store as far as I can tell. The stores are split up be remote office, and each remote office was experiencing the delay.

There was an inherited secuirty problem at the top level of my exchange, Administrators wasnt being inherited down the line. I made this change a few weeks ago and havent had the problem since so I think this issue seems to be solved.
