    Postoffice - Restrictions
    In This Topic

    Restrict the usage of particular messaging services e.g. restrict the number of messages sent per hour.  Setting a value for a post office here overrides any settings that have been created for individual mailboxes.

    Setting

    Explanation

    Limit Maximum SMTP recipients

    Throttles any mailbox from sending more than a configured number of emails per hour. This setting is useful for hindering spammers from sending and using the server as a source for spamming.

    Any emails to this postoffice must come from from authenticated connections

    If this setting is ticked then any message destined to mailboxes that reside under the postoffice will need to originate from an authenticated connection. Please see SMTP - Advanced SMTP for information on how to enable this option if greyed out
