• MessageIDGenerator

   private MessageIDGenerator() 

• generate

   public static String generate(String host_name) 

Generates a new Message-ID string.

Parameter

Description

hostname

The `domain' part of the ID to generate. Generally, this should be the fully-qualified name of the local host. In situations where that is impossible to determine, or where the local host name might be considered confidential information, the host part of the return address of the authoring user will do. If the provided host name is not syntactically valid, an error is signalled. The host name may be null; in that case, a random sequence of characters will be used for the host name, resulting in a syntactically valid Message-ID. Note, however, that this is strongly discouraged by the relevant RFCs: Message-IDs should have valid host names in them if at all possible.

Returns:

The new ID, a String.

• checkHostName

   private static void checkHostName(String string)
