If there's no MX entry, CNAME (or A) are used.

Close. It's a *prefix*. Mail to [EMAIL PROTECTED] will be delivered
locally to africaalive.org-foo.

That could be a problem, especially if you also don't have a
~alias/.qmail-africaalive:org-default file to "catch" the virtual
domain's mail.

qmail doesn't use /etc/aliases unless you have fastforward
installed. It never uses /etc/aliases.db.
