---------------------------------
Resolution: Fixed
> Possible wrong calculation of header length
> -------------------------------------------
>
> 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
> Priority: Major
> 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
