Hello,
For messages with missing "MIME-Version:" you could also just detect
this and add that header via procmail before message delivery to the
folders --- if you use procmail. This is what we do at LuxSci.com for
this case.

Tan,
You may be interested in a piece of software called MIMEDefang
(http://www.mimedefang.org/). It basically interfaces with your SMTP
server (Sendmail etc.) and automatically fixes broken stuff for you as
the messages arrive, so imapd shouldn't ever see messages that don't
obey the RFCs. I think the main goal is so maliciously crafted
messages can't exploit a security hole in your MUA, but it might solve
your problem as well, and if you know perl, it's very customizable and
can do all kinds of crazy things.
Hope this helps!

Those double quotes are the problem. They are completely bogus
syntax, and prevent the parsing of the CHARSET attribute.
Hi Mark,
I removed the double-quotes and the e-mail is still not displayed
correctly. However, with the "MIME-Version: 1.0" added, the e-mail
displays correctly in both IMP and Pine.
Is there something I am doing wrong?
Assuming that you actually care about reading those messages, and
they are not spam, the only reasonable recourse is to tell the
individuals who manage the optionetics.com system that they need to
comply with the published MIME protocol specifications and not guess
at what constitutes valid MIME.
On a practical basis, it is impossible to make a parser comprehend
every possible invalid syntax that is dreamed up by some lazy
individual who refuses to follow the specifications. Equally
important, well-intentioned code to parse some invalid syntax is
likely to have the unexpected side effect of mis-parsing valid syntax.
The difficulty that I am facing is that there are many of such broken
mailers around (most of them appear to be newsletter applications)
making it almost impossible for us to request them to fix their
applications.
What makes it even more difficult is that usually other e-mail
clients like Outlook Express, Thunderbird and even Gmail are able to
parse them correctly. This makes it extremely difficult to convince
these individuals to comply with the published MIME protocol
specifications, and we usually get a retort like: "It works in
(client X) but not yours, so it's clearly your problem." :(
Cheers,
