B.2 Invalid Characters in Internet Email Addresses

Internet email addresses must include only RFC-compliant characters, which include:

  • Numbers 0-9

  • Uppercase letters A-Z

  • Lowercase letters a-z

  • Plus sign +

  • Hyphen -

  • Underscore _

  • Tilde ~

In the names of GroupWise objects that can appear in email addresses (users, distribution lists, and resources), use underscores (_) rather than spaces as separators between words to facilitate addressing across the Internet.

If it is important for GroupWise object names to include characters that are invalid in email addresses, you can set up preferred email IDs for those objects in order to give them valid email addresses.

For instructions on providing valid email addresses for GroupWise objects, see the following sections in the GroupWise 18 Administration Guide:
