Generally speaking you do not want to have per-user DMA configs at
all, it's just too big of a security risk.
What you could do is allow user extensions ala postfix style '.'
extensions to the target name. For example:
[EMAIL PROTECTED]
[EMAIL PROTECTED] <--- also routes to dillon
The per-user aliases file (~/.forward) can pipe to programs, which
means it really has to be run in the context of the user. DMA itself
does not have to run as root but you will need a local delivery
agent that either runs as root or is suid root.
