Depending on the type of mail server used for ChangeMan DS, different results are seen. Each mail server can be configured to modify an email notification. For example, the name displayed on the TO line of an email can either be gathered from the FULL NAME value on a DS user, or a mail server can display the TO name of what it thinks the FULL NAME of the user that is associated with the email address is.
The symptoms "USING THE FULL NAME" for the TO line is a correct assumption. The issue was that the particular mail server used was not parsing the FULL NAME correctly. Therefore, by putting the FULL NAME in quotes, caused the name on the TO line to display correct.
Using non-POA to send email notifications causes only the userID that the email is being sent to to appear on the "TO" line. Because of the difference in behavior, it can cause problems when too many email addresses appear on the "TO line". It can cause some mail servers to garble the message header.
