Can a CRM 2011 Queue read emails sent to more than one email address ?

I have a mail box that receives emails sent to Support1@company.com and also Support2.company.com

I've configured a queue for Support1@company.com but also want emails to Support2.company.com to go into that same queue.  Can I make the queue read emails to multiple email addresses?

( what's also interesting is that emails to Support1@company.co.uk are also read into the queue fine - suggesting queues may only be matching on the part of the email address before the @ sign).

Thanks,

Stuart
