Wrapping Up
The next time you see your E-mail administrator pulling her hair out while muttering about spam, viruses, worms, blocks, and more, hopefully you'll have a bit more sympathy. This is a major time of change for experienced E-mail administrators, and many people running E-mail servers these days were just thrown into the job rather than really having the background in the first place. Having to learn this vast array of new skills can be both stressful and rewarding, but in the meantime there's still a job to do.
At least now you can look forward to the look on the E-mail administrator's face when you tell her that your users are having problems connecting to the MSA, but the MDA is working just fine.
