SUMMARY: sendmail MASQUERADE_AS

Thanks to Crist Clark, R A Lichtensteiger, and others for helping me with this.

Crist figured out that one of the rules using Canonify2 should be deleted, which fixed the problem. I did a little more investigating, and discovered I was using subsidiary-v7sun.mc as a model, and should have been using main-v7sun.mc. Started over from there, and all is well.
