Howto decode encoded mail subjects?

ruby-talk
1

Hi,

i need to parse mails. Some of the Mails in question use some ending
scheme to support sepcial characters which are not ASCII-7.

encoded chars look like this: =?UTF-8?Q?=20some text...?UTF-?Q?...

Is there a way to decode these subjects soemhow to real utf? Then I
could use Iconv to change the encoding as i like.

Any tips appreciated!

Cheers,

Steph.

Half a year ago I wrote me a mail filter that does much more
than only decode header fields. I post some example code for
your task below.

I use the filter every day since last December. I provide it
as open source but I think nobody else is using it. So I
cannot estimate how good the documentation and the
installation tools are.

Oops. I just forgot the link:

  <http://opensource.bertram-scharpf.de/sites/cropmail&gt;

thank you for providing the link. Maybe you should announce cropmail on
rubyforge to gain more users. I guess nowadays most people look on
rubyforge first when looking for ruby-related stuff.

Cheers,

Steph.
