|Subject:||Which INDY version is usable?|

I am implementing an anti-spam filter into our company's
mail server and I'd like to use INDY for it.
I need the functionality of tidPOP3 and tidMessage so
that I can load a *.eml mail file, check it for some
spam characteristics, modify the "subject" line if I
think there's spam in it, and save the file again.
The basic concept is like this:
If CheckSpam (message) then
message.Subject:='SPAM! ' + message.subject;
I had a terrible time using Indy 9.0.14 because some
basic functionality (tidmessage.savetofile) is
broken and causes access violations.
Moreover, the MIME decoder/encoder all by itself changes
the MIME boundaries in the mail and corrupts some 20 %
of the e-mail messages it processes, so that Outlook
Express displays a blank body.
I downloaded the CVS snapshot of Indy 9 only to find that
the MIME processor was even worse.
So I thought I'd give Indy 10 a try, but my memory monitor
shows it has memory leaks which makes it unusable.
I'd rather not re-write the whole MIME parsing stuff. Could
a kind soul give me some advise as to which Indy version is
the most stable in the POP3 / Mime disciplines?
Or maybe point out an alternative library that works?
