SMTP Connector Question

I am admitedly not an Exchange expert though I manage a server on a Windows domain.  Occassionally, we will have a problem with delayed messages:

Subject: Delivery Status Notification (Delay)
 <<ATT1007474.txt>>  <<FW: Talking>>
This is an automatically generated Delivery Status Notification.
THIS IS A WARNING MESSAGE ONLY.
YOU DO NOT NEED TO RESEND YOUR MESSAGE.
Delivery to the following recipients has been delayed.

Typically, we use a smart host connector provided by our ISP.  Why?  Not sure I can answer that.  At other times, I simply set SMTP to "Use DNS to route each address space on this connector".  What seems to determine which method I use is based around what ever clears the queues when they begin to stack up.  I know this cant be the correct way of doing things.  This AM, frustrated after nothing I did seemed to clear the backlog in the queue (over 1600 messages stacked), I purchased an outbound connector service which I actualy read about here on experts (Mailhop Oubound relay svc. from dyndns.com).  As soon as I forwarded all mail through their outbound server, the mail began to clear out.  Since it's an outbound connector only, I had to resort back to one of our ISP's connectors.  RIght away, mail started to stack up again.  A few moments ago, I set it to Use DNS to route each address space on this connector again and the queue cleared.

What am I doing wrong?  Thanks.

What?

Pointing an SMTP connector to an "outbound only" server does not mean you won't receive mails directly.

If you have bought that service from DynDNS, you have made a good move - keep the connector pointed to that server

Ah!  I didn't follow through with the authentication portion of the implementation!  Thanks for your help - my queues are cleared!  It is a great service indeed.  Now to just figure out how many relays we'll ned to purchase.  Are you using this yourself?

Answer:
I am using this service myself at one site, it is relaying for 3 domains - i am not aware of any restrictions on domains, only mail flow (ie., number of messages)
