Windows 2000 SMTP

Ok, I will explain as clearly as I can.  I am running a windows 2000 server with the following specs:
PROCESSOR: PENTIUMR-4  1.8GHz 512K CACHE
MEMORY: 512MB PC2100 DDR ECC REGISTERED
HARD DRIVE: IBM 80.0 GB EIDE HD 7200RPM
CASE: SuperMicro 2 U Rackmount
CD-ROM Drive: 52X max.
OPERATING SYSTEM: WINDOWS 2000 SERVER

I run mail lists for clients, sometimes 5000 per day, sometimes 100,000 per day.  When I first fired up this box it seemed to be running just fine for about 8 days, doing about 250 mails per minute, which I can live with.  On day number 9 it has slowed down to a crawl, maybe 20 per minute.  Would this have something to do with the mail que?  I am not sure where to look.  Also, when I mouse over on the quick start icon on the bottom menu bar, it says millions of packets "sent received". I am really a perl programmer, I am not sure where to look on why this is happening.  I rebooted server, same thing happens. I have Microsoft Exchange running with a mail program called Dynamic Mail Communicator (DMC) which allows me to personalize my clients list.  The specs on the DMC state:
Bandwidth  Data Rate (bits per second)  Emails / hour *
 56K Modem  56 Kbps  3000
 ISDN  128 Kbps 6500
 Cable Modem/ADSL  512 Kbps to 2 Mbps - typically  20,000-100,000
 T1  1.54 Mbps  50,000
 T3  45 Mbps  1,500,000
 So DMC can deliver, so it must be something with SMTP or server since it ran fine for a week and then now slowwwwwww.  Also, this is for client lists that is provided to me, I provide personalized newsletters and such for clients.  As I said, it ran great for 8 days or so, now it dogs it for some reason, I just do not know where to look or begin to look.

Thanks in Advance....

Harleyjd is exactly right. That is why I wanted to know if you were running exchange ON that same server, because it is not managed via IIS console.
I think your about to get it sovled with the afore mentioned from harleyjd

Ok guys, this is what I see...

In the Internet Information Services I do not see a Default SMTP Virtual Server, I only see a Default NNTP Virtual Server (stopped), also there is mydomain ftp site, my domain website, admin website.

In the Microsoft Exchange System Manager I see the queu and the mail does seem like it is mine.  Seems like a lot of mail in there.  I know some is delivering since I do a client seed so they see their message.  I do not see an advanced tab only a settings which it seems only option is the resfresh rate of time, it is set at 2 minutes.

What is the freeze and unfreeze, I assume what it means....

THe advanced button is on the delivery tab.

Frezze/unfreeze will stop retries or do an immediate rety...
