Help with Postfix Virtual Domain Mapping

Hello,

I am running Virtualmin on Ubuntu 7.10. Everything is working beautifully and exactly how I want it to except for a small problem with the way Virtualmin is mapping users for my virtual domains. In the Default Server Template, I specified that I wanted the format of the mail addresses to be user@domain.com and the user is being added correctly.

The problem is that when Virtualmin adds the user mapping, it maps user@domain.com to user-domain.com; I would like it to simply map to user@domain.com instead of user-domain.com. Is this possible?

Thank you in advanced.

Best Regards, dimpared
