Out-of-Office Rule that fires for an entire domain

[Bryan L]

I'd like to set up a rule that fires on all mail received from a particular
domain. I tried setting up a rule where the "From" field was configured
with a domain name only (From: specificdomain.com). I tested by having
someone from that domain send an email to the user, but the rule did not
fire. Is there a valid syntax for creating a rule that should fire for all
email from a particular domain? It's not practical in this case to set up
multiple rules to fire on incoming mail from full email addresses since
there would be far too many to configure.

Thanks,

Bryan

Clarification: I'm setting up this rule for a specific user only. All email
sent to this user from a particular domain should cause the rule to fire.

Thanks again in advance.
