How do I limit attachment sizes for inbound and outbound internet email using FirstClass 7.1?
Limiting inbound attachment sizes can be accomplished via the All Mailboxes user group permissions or the individual MailBox permissions. Simply set the Limit messages above: to the desired maximum message size. The example below shows that a limit of 50KB has been set. Please note that this limit also includes the body of the message.
Any message, either from the Internet or from local users, that exceed this limit will be rejected with the following NDN:
Limiting outbound attachment size can be done via the Internet gateway's permissions. On the admin desktop, open Gateways, open Internet, then click on Permissions. Simply set the Limit messages above: to the desired maximum message size. The example below shows that a limit of 50KB has been set. Please note that this limit also includes the body of the message. This affects all users.
Any message that is attempted to be sent out to the Internet that exceeds this limit will be rejected with the following NDN:
In both cases of inbound and outbound, any change made to the size will take place immediately
How can I block internet mail from being sent to an individual user or conference?
The only way to block inbound Internet email is to log in as the admin, go to Internet Services, open Advanced Directory, go to the Aliases tab and configure to Do Not Create Automatic and Aliases Only (see below), HOWEVER every user or conference that is to receive internet email MUST have an alias in their Mail Aliases field of their User Information Form (for users) or Directory Information Form (for conferences).
Ensure that the user or conference that should not receive email has a blank Mail Aliases field (see examples below). You will have to restart Internet Services for the changes to take effect.
When an internet email is sent to the user or conference, a bounce message will be generated stating that this is an invalid recipient address.
How can I block internet email from being sent by a user group or individual user?
Log in as the admin, go to Gateways, open Internet, click on Permissions, and add the user group or user as Disallowed at the top of the permissions (as shown below for user Will J. Stuart). You will have to restart Internet Services for the changes to take effect.
When the user attempts to send a message, they'll get a bounce message indicating that they do not have send access.
Please note that this will not affect internal FirstClass email.
