The email2ncid gateway has an option to only send an email subject line to the NCID server. It is called from a .procmailrc file when the email address or name matches on the email "From:" line.

The email must be in either plain text, or HTML and plain text. The output of email2ncid is a one line NCID message sent to an NCID server.
