Different Mailboxes

Summary

We have different emails set up for 1 mailbox

Content

We have multiple emails set to one mailbox. We are trying to run a rule that filters these emails out by the receiving email address. The tech service seems to be taking the email and funneling it to our mailbox but that in turns wipes any memory of the original email address. For example,

Someone sends an email to out help@help.com and it goes into our ask@ask.com mailbox. The console is saying the email was sent to ask@ask.com instead of help@help.com. So we have no way to filter this in the email header. Their is no mention in the audit log.
