    Default Group Email Question

    We are currently running 5.0.5 Server on a Ubuntu box. We have a Staff group email address of staff@myco.com. One of the employees have Outlook at home and their computer was infected with a virus. We now are getting a lot of spam on the group email. My question is can we limit staff members to be the only emails to send anything through the staff@myco.com ?

    There's no easy GUI or CLI method of doing this at the moment; but it's possible with some Postfix re-configuration. There are some details in the wiki - RestrictPostfixRecipients - Zimbra :: Wiki.

    Two bugs you may wish to vote for:

    Bug 9620 - Mail policies and access control for sending to distribution lists
    Bug 7104 - Distribution List Restrictions

    I noticed that
    "This method can be spoofed by forging the MAIL FROM: header (so mail appears to originate from within the domain), so it isn't foolproof, but it works for basic needs"

    And this is currently our biggest issue right now. We will receive message from staff members but the sending SMTP is overseas.
