Lotus Protector for Mail Encryption (LPME) or Symantec Encryption Management Server (SEMS - formerly known as PGP Universal Server) encounters UTF-8 errors when processing RightFax Fax Emails.
There is potential for Lotus Protector for Mail Encryption (LPME) or SEMS to encounter UTF-8 errors if attempting to send/forward certain RightFax fax email content through the LPME Server.
LPME or SEMS are RFC compliant servers and when encountering illegal characters/formatting in messages, a UTF-8 error may be displayed.
When sending a RightFax fax email, several Quoted Printable (QP) encoded attachments may cause this.
One cause of this issue is due to a RightFax Fax EMail "Charset" parameter missing in the "Content-Type" MIME header of the message.
If a file was called OCR.TXT, below is an example of this problematic formatting in the header:
Content-Type: text/plain; name="OCR.TXT"
Content-Disposition: attachment; filename="OCR.TXT"
Content-Transfer-Encoding: quoted-printable
This is an example of the expected value for a properly formatted header:
Content-Type: text/plain; name="OCR.TXT";charset=utf-8
Content-Disposition: attachment; filename="OCR.TXT"
Content-Transfer-Encoding: quoted-printable
The proper value missing is in the first line of the header in this example is called:
;charset=utf-8"
The following methods may be used as workarounds to this issue:
Method 1:
Use only Base64 encoding when composing these RightFax Fax Emails.
Method 2:
Add the "charset" parameter in the "Content-Type" mime header for QP encoded messages.
Ensuring these illegal QP encoded headers are not missing will avoid this issue.
Method 3:
Do not forward these fax emails with the text files, and only send picture files, or pdf files.
Another workaround to this if changing the encoding type, or modifying the Content-Type fields is not possible is to remove the attachments as they appear and either zip them up, or send them another method.
