This tip will show you an easy way to set up "alias" eMail addresses. We publish "alias" eMail addressess on our printed advertising, that way, if job responsibilities change, I can just point the "alias" to the new person. This is also good to do when you need to enter an eMail address on web form. I use my alias name, then, when I start getting spammed on my alias name, I simply delete it.
In the public name and address book, edit the person doc that you want to add an alias to. In the "User Name" field, add the "alias" name to the end. Make sure it is unique. Save and Exit. Then you can send mail to ALIAS@YOURDOMAIN.COM. Simple.
