A message sent from an *alias* of an ASK-filtered
account will automatically add the actual address to
the whitelist and go through.
For example, I have an alias "sales" which points to
"burma". Any message spoofed from "email@example.com"
will automatically add "from firstname.lastname@example.org" to the
whitelist and get delivered. And each succesive send
from "email@example.com" will add a new duplicate
entry of "from firstname.lastname@example.org" to the whitelist.
One solution of course would be to add
"email@example.com" to rc_mymails. On this system
though, there are *many* aliases for
"firstname.lastname@example.org" and they are often created
on-the-fly and from remote locations. So if the only
solution were to add those aliases to rc_mymails, then
that is a usability bug in my opinion.
