Hi Tomasz,
Thanks for notifying me about the problems...
I forgot to include in the qmail post that I _only_ tested
the script on M$ Client (MUA's) emails.
I know what you mean. I did a test mail from another MUA
and it shows that it is not using the "Content-Description:".
I will look into this and make some changes on the script.
That's the good thing about posting your script to the Iist.
Someone can find the problems :)
With regards to the "Application". Again this was based on
the M$ Client (MUA) email. When an M$ Client sends an email,
I noticed that it uses e.g. "Content-Description: Virusprg (Application)".
The "Application" here is _not_ the same as the "application" you
can find in the entry "Content-Type: application/octet-stream".
They are totally different. But I will look into this and improve the
script.
I would appreciate however if you can make some suggestions
on how to improve the script.
Thanks,
Noel Mistula
