Remmelt Pit created MIME4J-256:
Summary: DefaultMessageBuilder.parseMessage should honor
MaxHeaderLen over MaxLineLen
Project: James Mime4j
Issue Type: Bug
Affects Versions: 0.8.0
Reporter: Remmelt Pit
Upon parsing a message using DefaultMessageBuilder.parseMessage(InputStream),
the max header length is measured _after_ max line length, even for header
lines. This should not be the case.
Our use case is to support body line lengths up to 1,000 characters, and header
lines up to 10,000 characters. This is the default as found in
>From these defaults, it would seem that header lines are measured differently
>than body lines, and can be longer.
This is not actually the case, since header lines will also be measured like
body lines, even _before_ they are measured as header lines.
String messageText = "From: f...@example.com\n" +
"To: t...@example.com\n" +
MimeConfig mimeConfig = new MimeConfig.Builder()
DefaultMessageBuilder messageBuilder = new DefaultMessageBuilder();
What I would expect to happen: Message is created without exception.
What actually happens: MaxLineLimitException is thrown because of the "From:"
For now a workaround could be to set the maxLineLength to -1, to disable that
check. We don't want to run without the body line length check, though.
