[otrs] Design Question - coming from RT

Hello All: I am moving over from years of using RT and am excited about this product. I am trying to figure out a fundamental design question and hope someone can provide a short answer. In RT, incoming emails to particular addresses, say noc@, abuse@, peering@, are automatically directed via Sendmail aliases pipes to individual queues within RT. I can't figure out how to accomplish this task in OTRS. Once thing of note, the mail server that fronts these addresses has no POP accounts presently; all mail is forwarded via aliases to other servers for selective processing. Is it possible to keep this model with OTRS or do I need to change the way I view local mail delivery? Thanks, Mike
