[cobalt-users] selective autoresponder?

["Peter Hoelsken" <hoelsken@xxxxxxx>]

I've modified my RAQ2 to accept email aliases like alias@xxxxxxxxxxx This
was necessary, because one customer wanted to change his domain from
olddomain.com to newdomain.com, but he still had to receive mails addressed
to his old domain. So now every user has 2 aliases like "alias" and
"alias@xxxxxxxxxxxx". Everything is running fine. But it would still be
intersting to have the autoresponder sending a notification to everyone
addressing the old domain with a statement like "Please use
alias@xxxxxxxxxxxxx".

Is there any way to have the autoresponder selectively respond to only
certain messages, in this case messsages addressed to alias@xxxxxxxxxxxxx?

regards,

Peter
