How to create mail groups
You can set up mail groups by using the email forwarding feature. (Need help creating an email forwarder?)
Create a mail box which will represent the mail group. (ex. CompanyGroup@example.com)
Then add all the email accounts in the group to the Forward To field. Each email address should be on a new line.
Select ‘Do not store forwarded mail’.
Any email sent to this account (ex. CompanyGroup@example.com) will be forwarded to all the emails listed in the Forward To field.
