Raffaele Gambelli commented on MIME4J-265:


sorry but I don't understand if you think it is a real issue and so if you think to resolve
it, I would have the need to know it and possibly when.

Really thanks, bye

>             Project: James Mime4j
>          Issue Type: Bug
>    Affects Versions: 0.7.2
>            Reporter: Raffaele Gambelli
>            Priority: Major
>              Labels: headers
> I've implemented a sort of mail server and I have many threads listening for incoming
> 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
> Thanks
