The email record will have a blank email body.
The email log has a message Attachment: ,text/plain
An attachment that contains the email body text may be attached to the target record.
The headers contain Content-Disposition: inline
Madrid and higher.
Starting in Madrid, there was a change in design where if the email headers contain Content-Disposition: inline, we assume this means it is an attachment. However, in some cases, the customer is sending text inline.
Some email clients, such as the Mutt email client, include the Content-Disposition: inline header; therefore, emails sent by such email clients to a Madrid or higher instance are prone to experience this issue without the resolution below.
To revert to the pre-Madrid behavior:
1. In the Application Navigator, enter sys_properties.list
2. Click New.
3. Click Submit.
