We have multiple email accounts. One particular email when recieving emails it is always copied to another email. How can I change this.

The email accounts were created by the administrator prior to me. We have multiple email addresses (Using Thunderbird) and when we send an email from one particular email address the response will come back to that email address and one of our other email addresses. How can I stop this from happening?

I checked those settings and everything seems to be correct. There is no email (s) listed in the CC or Bcc email addresses.

Check Message Filters: either via Mail toolbar: 'Menu icon' > 'Message filters' > 'Message filters'. Or via 'Menu Bar' 'Tools' > 'Message Filters' see if there is a Message filter for the account which is sending a copy to the other email address. disble or delete as required.

Checked the Message filters and did not see anything being directed or sending a copy to other email addresses. I did notice that all emails are IMAP and the one that the emails are getting copied to is a POP. Would that have anything to do with it?
