Could someone explain how Domino handles messages send to large distribution groups that expand over several mail servers. I’m just wondering how much redundant traffic we are generating every time one our administrative assistant decides to shoot off an e-mail to the entire company. Does Domino send one message to the other servers specifying the recipients for the particular that server and then that server generates the message to deliver, or does generate a 1000 messages and they all find there own way to their intended users.
If I lived in a perfect world where IT had full control over the policies and procedures in our organization I too would not allow users the option to SPAM everyone. I know Exchange can handle this with out redundancy, but like I said this isn’t a perfect world. Domino is this organizations flavor of the week mail solution and the owner want his administrative assistant to have the ability to SPAM the entire company . . . I just want her to be able to do it efficiently.
The router only sends a single message to the other server, it then delivers the message to the multiple repients.
From the Help DB:
Restricting users from sending mail to groups listed in the Domino Directory
By default, all users can send mail to groups defined in the Domino Directory. To reduce unnecessary mail traffic, you can edit the reader fields for a Group document to restrict access to the group, specifying the users who are allowed to send mail to the group. Only users to whom you grant reader access can send mail addressed to the group. Users who do not have access to the group can see the group name listed in the Domino Directory and choose the name in the Select Addresses dialog box, but the Router rejects the message if they attempt to send a message to the group.
The restrictions apply to messages sent to either a group’s Notes address or its Internet address and to messages originating from a Notes client as well as messages sent and received over SMTP (as from an IMAP or Notes client). From a Notes client, a user who does not have permission to use the group receives an error when attempting to send mail to the restricted group. If the same user attempts to mail from a POP3 or IMAP client, the Router generates a Nondelivery reports indicating that the sender is not authorized to send mail to the specified recipient.
To restrict users from sending mail to a group
From the Domino Administrator, click the People & Groups tab, expand the Domino Directory that contains the group you want to restrict access to, and select the Groups view.
Right-click the Group document to manage and choose Document Properties.
Select the Security tab (the Key).
Deselect the All readers and above checkbox to enable editing of the readers list.
To enable a user to send mail to the group, select the user’s name in the list.
To provide access to users not listed, click the Person icon to the right, add the name in the Select Names dialog box, and click OK. The user’s name appears at the bottom of the list with a check next to it.
Deselect the names of users you want to prevent from sending mail to the group, including the Anonymous entry.
This is not entirely true. The statement “Users who do not have access to the group can see the group name listed in the Domino Directory and choose the name in the Select Addresses dialog box, but the Router rejects the message if they attempt to send a message to the group” is false. If the group is restricted with the readers field, only those with reader access to the group can see it.
That’s correct. The users who don’t have access cannot see the group. If they know the group name they can type it in, but they will get a failure report.
I have restricted email to groups in the manner prescribed here. Users cannot see the groups, but if they do type them in blind, and then override the pop up “No match found in Name and address book”, by pressing the send anyway button, the email is delivered to all members of the group.
If it is of any relevance the above happens when using an iNotes webaccess client, created with an R5 template.
I have not tested with either a full notes client, or an R6 template, although I would have thought this irrelevant if the router is supposed to reject the email.
