Problem: Messages arriving from the Internet through the Internet Agent addressed to recipients who have extended characters in their user names are undeliverable.
Explanation: User names are part of message header files. According to RFC822 and RFC1521 standards, text in header fields must be composed of printable ASCII characters.
Action: As a workaround, create a nickname for affected users without the extended characters. See "Creating a Nickname for a User" in "Users" in the GroupWise 6.5 Administration Guide.
