Rule-based mode

In this mode, messages are analyzed by server-side rules and eventually moved into Cryptshare.nsf for further processing.

Create server-side mail rules

You can manage mail rules in the Domino Directory in the section "Configurations" - "Server" - "Configurations"

Edit the server configuration document and select the tab "Router/SMTP", then "Restrictions and Controls…​", then "Rules". Here you can create new rules or edit, delete or disable existing rules.

If you use a product from a third-party vendor to manage mail traffic rules, you can create rules in the same sense as described below using the product of the third-party vendor to configure the rule-based operation of Cryptshare for Notes. Please note the manufacturer’s instructions.

A server-side rule for email messages might look as follows:

  • If the number of attachments is larger than 0,

  • and the total message size exceeds 10.000.000 Bytes (approx. 10 Mbyte)

  • and the form name equals "Memo"

  • and the sender contains your organization name (e.g. "/befine/DE")

  • then the message will be moved into Cryptshare.nsf.

CS4N scans Cryptshare.nsf on a regular basis for new messages to process.

Setting up rules in the Domino Directory

  • Make sure to include the forms "Memo", "Reply" and "Forward" into you rule to cover all types of messages that can be sent form a Notes Client.

  • New rules will only become active when the server re-loads the email rules from the Domino Directory. Re-loading takes place every 5 minutes when the server task checks the configuration documents. Use the following command on the Domino Server console to trigger re-loading of rules manually: set rules

  • Check the policies for senders/recipients allowed to use the Cryptshare Server. The policies for the Cryptshare Server must grant permissions to ex-change files to the same group of users as specified in CS4N.

Advantages

  • A central set of rules can be defined which is mandatory for all specified users of the system.

  • The user doesn’t need to take or consider taking any action.

  • No software roll-out is required on the Client side.

  • The users will just need some basic instruction. They need to understand the auto-generated message that Cryptshare sends back to the sender.

  • The router/mail.box will not have to handle large emails.

  • To distribute the traffic load in a system with several mail.boxes, a number of CS4LN installations can be used.

  • Messages of any size can be delivered regardless of restrictions for the mail-box size or the message size that may exist on the sender’s side.

Important information

  • With large email traffic, the CS4N application (Cryptshare.nsf) may take up a significant amount of storage space.

  • Lotus Domino’s "compact" task should be run against CS4N daily.

  • The emails processed by Cryptshare bypass the standard mail route and may have to be monitored separately.
