Correct. The handlers do that whenever a user is added, deleted or modified.

I doubt that. CMU doesn't mess with Sendmail other than adding users and 

Are you by chance using CNAME records for your DNS? Because if you use CNAMES, 
the exact behaviour you described will happen:

Emails to username at domain.com go through, but emails to alias at domain.com 
cannot be resolved.

Sendmail can't cope well with CNAMES, which is one of the reasons why one 
shouldn't use CNAME records on mailservers - or on BlueOnyx in particular.
