Why is some text removed from email subject lines?
February 2010 version and newer
These strings are removed by the Techmail utility automatically starting in the February 2010 version:
- Incident reference numbers that are not valid for the site
- Non-ASCII or invalid encoding characters
A subject line in an email should always be ASCII characters. If the subject includes non-ASCII characters then the subject should be encoded in either quoted-printable or BASE64. Techmail will then decode the subject to the appropriate characters.
