Exchange 2003 SMTP Service - Without Exchange

Learn something new every day...

I was working with a new client today, on an SBS 2003 computer, and they use external e-mail.

However, the original technican that had done the installation of their server had gone through the process of installing Exchange Server, and then disabled all of the services that start with "Microsoft Exchange..." in the Services applet - but they hadn't disabled the SMTP service. As you may know, when you install Exchange Server 2003, it overwrites the Windows SMTP service with its own version of the service that "speaks Exchange".

Whenever I go into a client, I always like to be able to use a local SMTP server to send daily status report to me, for monitoring, and just general e-mailing. Usually, in an SBS environment, I'll use the Exchange SMTP service and if Exchange isn't installed, I'll simply install the Windows SMTP service. This allows me to get around all of the usual problems associated with secure relays, etc. etc.

So, in this case, I was sure that the SMTP service wouldn't work.

I was wrong. The SMTP service works just fine for relaying. You can't manage the SMTP service from the normal IIS Manager, you still have to go to the Exchange System Manager to make changes. But it works just fine.

 Like I said, learn something new every day...

Until next time...

As always, if there are items you would like me to talk about, please drop me a line and let me know!

This one I knew. My boss had "shut down" Exchange after we were assimilated in an acquisition. Unfortunately, he neglected to disable the SMTP service and mail was still being relayed from some legacy processes.
