> MIME4J-55 showed issues with very long multipart mime boundary.
> It has been fixed by having the buffer size depending on the boundary length. This create possible issues (OOM/DoS) with malicious messages.
> It would be good to define a maximum length for an header.
> Somewhere in mime rfc or smtp rfc there is a maximum of 998+CRLF ascii bytes per line, of course we may want to support longer headers, but not very long ones.
