Description of when Domino places MIME-part bodies into $FILE fields

Domino will place MIME-part bodies into $FILES fields if one of the following conditions is true:

1. Any time the size of the individual part's headers and body data exceeds ~40KB.

-OR-

2. Any part with "content-disposition: attachment", with the exception of composite types, i.e., multipart/<subtype> or message/rfc822. However, the subparts of composite types are subject to the same guidelines.

In addition:

In Domino 6.5.4, and 7.0, we introduced the ability to force non-text, content-disposition: inline, to attachment, when the Notes.INI included: MIMEForceAttachments=1

In Domino 6.5.6, 7.0.3, and 8.0, we introduced the ability to force All inline parts, including text, to attachment, when the Notes.INI included: MIMEForceAttachments=2
