assuming we're talking about some PEAR code and not a PECL extension then
you can just grab the relevant files from the PEAR site and upload
them to your site same as you do all your other code ... PEAR stuff
doesn't actually need to be installed ... it just comes with a cool management
tool that makes keeping stuff up2date and avoiding multiple copies, easier.

Does dropping the "quoted-printable" header make any difference? As far
as I can see you are sending actual 8-bit UTF-8, not quoted-printable.

As you didn't say explicitly, have you confirmed he can receive an email
(e.g. sent by thunderbird) in UTF-8 encoding, with umlauts, and it
displays okay?
If so, send both versions to yourself (i.e. sent by thunderbird, and
sent by PHP mail()) and look at the source to see what is different.

Sorry, I missed this earlier: if you have mb_encode_mimeheader() then
you also have mb_send_mail(), which does all the hard work for you.
http://php.net/mb_send_mail
http://jp.php.net/mb_language
So, this might replace almost (*) everything you wrote:
mb_language('uni');
mb_send_mail('[email protected]', $subject, $message);
Darren
*: Except the reply-to header. You can add that: mb_send_mail() takes
the same optional 4th parameter as mail().

Hi Darren :)
Or, the other way around, is the $message really encoded with
"quoted-printable"? (example: $message =
quoted_printable_encode($message);)
I doubt, as the function 'quoted_printable_encode()' is available only
from PHP version 5.3.0 and most PHP installations still are 5.2.
You could use base64 encoding at the place of quoted printable:
When sending the string "Umlaute: äüöÄÜÖ" as subject and body using my
"evolution" mail program it gets encoded in the following way:
[...]
Subject: Umlaute: =?ISO-8859-1?Q?=E4=FC=F6=C4=DC=D6?=
[...]
Content-Type: text/plain; charset=UTF-8
[...]
Content-Transfer-Encoding: base64
[...]
VW1sYXV0ZTogw6TDvMO2w4TDnMOWDQoNCg==
So you could try "Q" for "Quoted-Printable" at the place of "B" for
"Base64" when encoding the subject, and "base64" as transfer encoding.
Of course you first have to encode the "$message" with something like
'$message = base64_encode($message);' (which should be available even on
older PHP installations).
Nowadays probably most of the internet can deal with 8-bit encodings
like UTF-8. But with base64 you can be sure that the content doesn't
get messed up during the mail transfer at least.

This was an obvious method which didn't come to my mind. Thank you very
much!
And thanks a lot to all of you who have answered to my request.
Again for all of you: My problem was "how to send UTF-8 - encoded emails
using the simple mail()-command, that display german umlauts well even
in outlook?"
The solution is very simple:
function sendEmail($to, $from, $subject, $message) {
// For security reasons: Make sure to parse the parameters
// before passing them to this function, or extend the code
// accordingly:
$charset = 'UTF-8';
$encoded_subject = "=?$charset?B?".base64_encode($subject)."?=\r\n";
$headers = "From: " . $from . "\r\n"
. "Content-Type: text/plain; charset=$charset; format=flowed\r\n"
. "MIME-Version: 1.0\r\n"
. "Content-Transfer-Encoding: 8bit\r\n"
. "X-Mailer: PHP\r\n";
return mail($to, $encoded_subject, $message, $headers);
}
As I found very few helpful information on this matter on the web and
probably more people have to cope with this problem than there are
experts out there, I hope this solution will be of use for more coders.
There are loads of possibilities to send emails, and there are loads of
header informations you can stuff inside, but finally and hopefully most
of you will only want to use a _working_ UTF-8-solution. We're in 2009
after all...
This solution might not be the best, and it doesn't solve the problem of
emails going right into the recipients (or the recipients mail
provider's) spam folder (for this you should send your emails using SMTP
with login-name and -password, e.g. using PEAR's "Mail.php"). But it
solved my problem.
Best regards,
Roman Blöth.
