IIS SMTP Loging

Hi all,

I have SMTP configured on a 2008 R2 server to relay emails to the Exchange 2010.

Today I received a call from a user telling that she was not receiving specific emails from a vendor.

After researching I find that she is able to receive email from users at the vendors location but she is not receiving emails from an automated system, and the vendor keeps telling us that they send it and show prove the email when out (but can't or will not prove a log".

My question is if there is a way I can record ANY attempt to connect to the SMTP server whether successful or failed?

Yes. You need to activate logging for your receive connectors in Exchange 2010:

Here is an article that will show you how:

The log files will then typically be stored here:

\Exchange Server\V14\TransportRoles\Logs\ProtocolLog\SmtpReceive

Hi,

In IIS6 there is your SMTP connector for which you can define logging, you might find there what you are looking for.
Also a nice place to start digging is c:\windows\system32\logfiles\smtp... files.

If this is not enough you need to enable firewall logging and find a way to exclude all attempt to (presumeable) port 25.

HTH

(this has nothing to do with exchange if you ask me)

If you find that the above logs do not tell you what you need, you can also activate logging in IIS. Fire up IIS Manager, click on Sites > Default Site.

Double click on Logging (in the IIS section), and check the right hand column to ensure it is enabled.

Log files for these are typically stored here:

\inetpub\logs\LogFiles\W3SVC1
