mike bell commented on MIME4J-140:
----------------------------------
Sorry I'm wrong about #2. No bug. Brain fart.
> MIME4J-57 is not practical in its limits and incorrect in its RFC
> interpretation

> Key: MIME4J-140
> URL: https://issues.apache.org/jira/browse/MIME4J-140
> Project: JAMES Mime4j
> Issue Type: Bug
> Affects Versions: 0.6
> Reporter: mike bell
>
> I have begun playing with Mime4j for potential use in a software project.
> Very quickly I found a simple email (Which i can attach) which has about 30
> TO addresses. The default was to throw an exception
> Looking at MIME4J-57 the author has misunderstood the SMTP RFC 2821. Yes you
> are limited to 998 octets PER LINE, but you may FOLD as many 998 octet lines
> as you wish. Technically it's 100% legal to have a 50 megabyte header value,
> as long as it is folded. (per 76 or 998 rules).
> I think the limit chosen by default of 1000 is absurdly low - this should be
> 100000 minimum or perhaps even unlimited by default. There is something to be
> said for a sanity check option, for sure - but not one that is triggered so
> easily.
> I can also open somewhat related JIRAS if people find them of merit:
> 1. Documentation - defaults should be clearly stated in MimeEntityConfig
> javadoc. They are not
> 2. Bug - The javadocs for MimeEntityConfig claim mc.setMaxHeaderCount(-1);
> would defeat; this check. It does not (I worked around with Integer.MaxValue)
> 3. Design Question: Should the MimeTokenStream not have a public constructor
> that allows MimeEntityConfig to be fed. As it was I had to create my own
> subclass to access the protected constructor - is there a reason for this?
> Thanks
> Example header that blew stuff up (and I think we've all seen far far worse!)
