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 [email protected] and it goes into our [email protected] mailbox. The console is saying the email was sent to [email protected] instead of [email protected]. So we have no way to filter this in the email header. Their is no mention in the audit log.
