In the Encryption Management Server Mail log, the email address of the outgoing message is displayed without quotation marks. For example:

When the Web Email Protection user clicks on the Reply button to reply to the message, it generates two of the Domain contains illegal character entries in the Web Email Protection log and when the user clicks on the Send button it generates a third entry.
Although the Web Email Protection log contains a total of three Domain contains illegal character entries for each message that a Web Email Protection user replies to, the reply does get sent. The log entry is accurately logged as an Information level entry. Therefore it can be ignored.
To avoid seeing these entries in the log, ensure that Outlook users do not enclose recipient email addresses in single quotation marks or create contact records with the email address in single quotation marks. Also ensure that Microsoft Exchange contacts are not created with single quotation marks around their email addresses.
