I am using IIS 6 SMTP server to send out some mail on our behalf. I am also storing each message we send in a SQL table - with a UUID representing each message. I would like to be able to inject additional data into the SMTP logs located in SMTPSVC1 - an additional field which would contain this UUID in the event of a RCPT cs-method call. This is so that I can check a one-to-one relationship between messages sent in SQL and messages actually sent through SMTP.

If possible, I would like to avoid writing a C++ custom logger as some sites I've viewed have suggested.

Is there an easily configurable way to inject this data into IIS 6 logs? Even if it was only the ability to perform a regex on the data/headers of the outgoing email, that would be enough.

Thanks!
