My Sharp MX-B401 printers can no longer scan to email

Hello all.  My office has 2 Sharp MX-B401 multi function printer/scanners.  Up until this week they had the ability to scan documents and email them to various mailboxes in my company.  Over the weekend, however, an email spammer gained access to our Exchange 2003 mailserver and proceeded to spam mail for a couple hours before our IT department was able to completely shut them out and clear our servers.  Along the way, one of our IT guys made some changes to our default SMTP virtual server properties, mostly in the ACCESS/Connection Control section where he banned several of the offending IP's and domains that the spam was originating from.  

Now, when our Sharp MX-B401's attempt to send scanned documents to email, they report that they can't connect to our server, and when I use the remote web interface to connect to printers, I can't connect to our SMTP server.  I have tried changing the primary server address from mail.[companyname].com to our mail server's IP address, I have tried forcing SMTP authentication with a username and password (prior to this, there was no SMTP authentication necessary).  I have also gone back into our Exchange 2003 and specifically granted our printer's IP addresses relay access.  

Strangely enough, I have another printer on our network (Canon-6000) that can still scan to email with no problems.  However, the webUI for that printer does not have any SMTP settings I can clone.  

Any suggestions on next steps?  I suspect our IT guy made more changes on the SMTP virtual server, but I can't find anything else I can reverse.

If you can, go back through the exchange logs to see if you can see the Sharp device trying to connect to the server to see what the issue is. It sounds as if you have tried about everything, but just in case try them again. Some items to check

1) Make sure the default gateway is correct (This has got me more than once)
2) Make sure you have the correct DNS entries on the web interface of the copier's.
3) Double check the domain name
4) Make sure the reply email account is valid (just under the reply email address)

If all of this still fails you still have a couple options. The first would be do a packet capture using a hub and wireshark to see if it sheds some light on why it is not working. The second would be use your ISP to "piggy back" off of there mail server. I have done this numerous times with success.

Can you go back to a restore point?... (before: "one of our IT guys made some changes to our default SMTP virtual server properties, mostly in the ACCESS/Connection Control section where he banned several of the offending IP's and domains that the spam was originating from.")?

Then re-do the banning of the several offending IP's and domains that the spam was originating from.?

Hello everyone and thanks for the replies.  

Reviewed the default gateway and domain name and they are correct.  Same with the DNS entries, the DNS and WINS servers.  I have changed the SMTP server name to the IP address and the FQDN.  I have even changed the reply email account to my email account, but no luck.  I still get a ERROR[3332]: Connection to SMTP server test failed error.

I have also tried to point this server to outside SMTP servers like gmail and still have the same error.  

I don't have a restore point for this server that I can roll back to.  

I will try the wire share suggestion in a while.
