I've added an email alias of DEV@domain.com to the HELP@domain.com mailbox

I'd like all tickets sent to HELP@domain.com to be assigned to HELP support group

I'd like all tickets sent to DEV@domain.com to be assigned to DEV support group.

I've created a business rule definition looking for the criteria of To: IS " DEV@domain.com", then perform the action of Place in group "DEV"

This does not seem to work.
