Oleg Kalnichevski commented on MIME4J-265:
------------------------------------------
bq. What is misleading is that maxHeaderLength is the total length of a header
(and not of a line).
Hence max _header_ length and not max line length
bq. The point IMHO is exactly that one, for what I know there is no overall
header limit, the only limit is on the single line
The MIME specification intentionally does not impose any specific limits on
MIME message elements and leaves it up to implementations to decide what is
deemed safe in their specific contexts.

> Key: MIME4J-265
> URL: https://issues.apache.org/jira/browse/MIME4J-265
> Project: James Mime4j
> Issue Type: Bug
> Affects Versions: 0.7.2
> Reporter: Raffaele Gambelli
> Labels: headers
>
> I've implemented a sort of mail server and I have many threads listening for
> incoming emails.
> I'm using mime4j to parse javamail Message.
> I had only one case of:
> Caused by: org.apache.james.mime4j.io.MaxHeaderLengthLimitException: Maximum
> header length limit exceeded
> at
> org.apache.james.mime4j.stream.DefaultFieldBuilder.append(DefaultFieldBuilder.java:63)
> at
> org.apache.james.mime4j.stream.MimeEntity.readRawField(MimeEntity.java:212)
> at
> org.apache.james.mime4j.stream.MimeEntity.nextField(MimeEntity.java:258)
> Looking at the code of DefaultFieldBuilder, it seems that the check over line
> length is not done on the single line but on the overall header, I'm refering
> to this line:
> {code:java}
> if (this.maxlen > 0 && this.buf.length() + len >= this.maxlen) {
> {code}
> Why should you add "this.buf.length" ?
> I know that there is no limit on header length, but only in its lines.
> I can't attach my eml for privacy reasons but I can confirm that I have no
> too much long line
> Thanks
