SpamAssassin: MIME_HEADER_CTYPE_ONLY 'Content-Type' found without required MIME headers

Sep 29, 2013 at 12:24 AM
Hello again :-)

When sending an email using the MailSystem.NET Library, SpamAssassin flags the email as Spam with the following flag description:

MIME_HEADER_CTYPE_ONLY 'Content-Type' found without required MIME headers.

This also happens when sending an email with one of the examples inside the library. Any help on this is appreciated because I couldn't figure out it by myself yet.

Thank you,
Corpy
