Importing allowed and blocked sender information If you have many senders and addresses to add to your Blocked Senders Lists or Allowed Senders Lists, it is often easier to place the sender information in a text file and then import the file. This section describes how to format that file. Maximum number of entries in an allowed and blocked sender file Be aware of the following limitations when importing senders: ■ The maximum number of sender lines per file when importing senders is 500,000. To add more (up to the limit noted below), divide senders into multiple files and import multiple times. ■ The maximum number of total allowed and blocked senders that can be stored is 650,000. ■ No warning is displayed if you exceed these limits. Sender data is silently dropped. Format of allowed and blocked sender file The file is line-oriented and uses a format similar to the Lightweight Directory Interchange Format (LDIF). It has the following restrictions and characteristics: ■ The file is in the installation directory, in the following location: /scanner/rules/allowedblockedlist.txt ■ The file must have the required LDIF header that is included upon installation.
