The IT support email account is the primary account and was setup in the mail server settings.

I aliased an email address for the Facilities Support under the IT support email account.

I am able to receive requests for the two groups.

I receive notifications and can reply to requests from the IT support group (because the email in the Outgoing tab of the mail server settings is the IT support email)

I am unable to receive notifications or reply to requests from the Facilities Support group (I have configured the email address aliased in the IT Support email)

Please how do I get the Facilities support group to send notifications and also be able to respond to requests.
