LuaSockets - smtp header problems

[Graham Henstridge <graham@...>]

Hi all

For us LuaSocket 2.0.1 is working really well except for two smtp
header issues:

1. When including attachments in an email, LuaSockets inserts the
follow headers into the attachment part:
	Content-Transfer-Encoding: base64
	Content-Disposition: attachment; filename="vibration.png"
	Content-Type: image/png; name="vibration.png"
	content-type: text/plain; charset="iso-8859-1"
The doubling up of the Content-Type (with different cases)
cause problems with MIME types on some email clients because
the second occurrence is incorrect. Any ideas why this might happen?

2. The original "From:" header as we defined it (same as Reply-To:)  
it is
missing in received email (but Reply-To is there). The ISP has
inserted a "From:" header, very different to ours. Emails sent via
standard program do not experience the substitution. Where are we
likely to be going wrong?

While not show stoppers, any help resolving problems greatly
appreciated.
