Geetha created MIME4J-314:
-----------------------------
Summary: Support for nested boundary parameter value as outer
boundary value with a prefix.
Key: MIME4J-314
URL: https://issues.apache.org/jira/browse/MIME4J-314
Project: James Mime4j
Issue Type: Wish
Affects Versions: 0.8.6
Reporter: Geetha
Attachments: mime_with_nested_boundaries.txt
We have mime messages which we need to support that have nested multipart where
the inner boundary parameter value is the prefix of the outer boundary
parameter value.
This format is not an RFC complaint from
[RFC2046#section-5.1|https://datatracker.ietf.org/doc/html/rfc2046#section-5.1]
which states that
The boundary delimiter MUST NOT appear inside any of the encapsulated parts, on
a line by itself, or as the prefix of any line.
In the example attached, the boundary
{color:#0747a6}-----Mail-Builder-Boundary-7972-1633093116{color} is used as a
boundary for (outer) multipart. Then for the nested multipart,
{color:#0747a6}-----Mail-Builder-Boundary-7972-1633093116-1{color} is used as a
boundary. *Note* that the outer boundary is a prefix of this nested boundary
and as a result, the Mime4J mime parser is not able to parse this content
properly.
Is it possible to allow this as part of Lenient parsing?
