One solution is to use a MLM that doesn't require a separate "alias"
to route messages to the recipients (eg mailman).
I certainly hope majordomo uses a local pipe rather than smtp to
inject the message to the list. If it does, another solution is to
make the user majodomo runs as a "trusted" user, and have it set
$received_protocol. This is done with the -oMr command line option.
Then add a condition on the director/router handling the alias
expansion to only accept if $received_protocol matches what you have
majordomo set it to.

Another (ugly) solution is to "remove" the alias until you want to
send out another newsletter, then reinsert it only for as long as exim
needs to expand it. This presumes that the list is a one-way channel
and isn't needed at arbitrary times.
