  • 1.  Symantec Mail Security for SMTP 5 - distribution list expansion: Will it collaps the list again?

    Posted Oct 02, 2007 05:41 AM
    Hi All
     
    I am running v5.0.1 of Symantec Mail Security for SMTP.
    In the console under Settings \ LDAP there is a check box to enable distribution list expansion.
     
    My question is: Will the system collaps the distribution list again once done?
    Will the e-mail still appear as being sent to the distribution list once it reaches the final recipient?
     
    I have not been able to find any detailed information about this, so some help is greatly appreciated.
     
    Thanks.
     
    /Thomas

    Hi Thomas,

    The expansion distribution list only expands the list to apply policies based on per recipient, so, to the final user this is transparent.

    Regards,

    Actually, that is not correct.  With group expansion enabled, the envelope recipient, which was originally the group address, has been replaced with the addresses of all the group members.  This typically does not cause any issues, but in the rare case of someone creating exchange/outlook rules based on the envelope recipient address, then it will matter. 
     
    In SMS 8300 Appliance, Symantec has introduced a new feature to preserve the envelope recipient while still performing group and alias expansion for policy reasons.  SMS appliance software will be available as a Virtual Machine for production deployment this December as an upgrade path for existing SMS SMTP customers.

    Hi Tim
     
    Thanks for the feedback.
    I have been looking at the 8340 appliance so your information is another item on the pros list.
     
    Thanks again.
