Exchange outgoing is too slow

By mg_roberts ·
We run Small Business Server 2003 with Exchange 2003. When we send mail to an outside host it can take up to 15 minutes for the message to be delivered. I'm sure as anyone can guess, to management this is not exceptable. Is there anyway to make the messages be delivered immediatly?

Mail Delivery Times

by BFilmFan In reply to Exchange outgoing is too ...

Remind managment that neither you nor they control the Internet. You also do not control how often other email systems check for email.

Recommend that your management purchase these other companies so that your email messages will all be stored on one Exchange server.

As a personal recommendation, I am willing to smack your management over the head with my patented iron skillet of management education which will make them much better managers....

consistent time

by mg_roberts In reply to Mail Delivery Times

I thought it might be a setting in Exchange because it seems that when there is a delay that it is consistently 15 minutes. I could very well be wrong though.

SMTP Connector Time

by BFilmFan In reply to consistent time

Use these steps to check the SMTP delivery times:

To view a virtual server, open the Exchange Management console and then expand, in turn, the Servers node, the Exchange server on which the virtual server resides, and then the Protocols and SMTP nodes under the server name.

Each virtual server includes three components: domains, current sessions, and the queues used for message handling and delivery.

Right click the virtual server and choose Properties.

Choose the Delivery tab.

Check the times listed. Note that it is in minutes.

You don't want to timeout too fast, as 15 minutes is generally the lowest accepted period for the 2nd Retry Interval.

What Problem??

by cyale In reply to Mail Delivery Times

The manager takes his car to the mechanic because it only goes 15MPH with his foot to the floor. They all wise mechanic tells him that that is normal and he goes away happy.

Any manager that buys that BS in today's business climate should be only allowed to drive 15 Miles an hour.

Some thoughts...

by NotSoChiGuy In reply to Exchange outgoing is too ...

Here are some things I have seen that impact the speed of Exchange (asides from the SMTP settings, which were already mentioned):

1). Take a look at your virus scanning, and see if there are settings that may delay outbound mail (just don't touch anything inbound).

2). Does your ISP perform any sort of SMTP gateway forwarding? If they collect SMTP traffic to scan before they send it along, that would definitely account for a delay. (I've had this happen to a few small clients)

3). Is the partition for the mail DB the same as the main file/print partition? If so, read/wrties to the drive could cause a bit of a drag.

4). Is the drive fragmented (sort of ties to the previous suggestion)?

5). How is your DNS resolution setup for external addresses? Do you get relatively quick replies to NSLOOKUPs done to the external mail domains, or does it seem to take a few moments? If it takes a bit, try connecting to a different DNS server, and see if that makes a difference.

Those are just some of the ideas I had off the top of my head. However, if the timing is 15 minutes consistently, as was pointed out already, it is probably something with the SMTP setup.

Hope this helps (or, at least, you find out what is causing the problem).

I'm just learning exchange. I have sbs 2003. Go to system manger -> connectors -> small business smtp connector. Rt clk -> props -> delivery options-> custom schedule-> select all. Please let me know if this worked

Outbound Config

by mball In reply to Exchange outgoing is too ...

How is your outbound mail sent to go? Direct or via a SMTP relay? Right now we have very little to help you solve this with.
