Email Forwarding to Addresses with Exclamation Points!

Hi,

Xero provides a unique email to allow emails bills to be forwarded to, and then be automatically added using Hubdoc. I would like to set up an “invoices” email with dreamhost that forwards to Xero, and then publish this address publicly to suppliers. Unfortunately, the Xero address has an exclamation point and Dreamhost does not allow emails to be forwarded to addresses with exclamation points.

This is something Gmail can easily do. In fact, as a temporary measure I have created a dummy gmail account, and I forward all emails from dreamhost to this gmail account, and then from gmail to Xero.

I would very much like to be able to cut Gmail out, and simply forward straight from Dreamhost to Xero.
