[Mailman-Users] Special characters in the subject line deleted

Hi all,

we are using mailman 2.1.12 and postfix on our own server and we are currently having some issues with special characters in the "subject" line.

When I send a mail with the test subject "Umlauteäuüö" to a list, procmail delivers the mail to mailman with the header line "Subject: =?iso-8859-1?B?VW1sYXV0ZeR1/PY=?=". 

The mail from mailman to the list-subscribers has the subject "[Testlisteäü]Umlauteu". i.e. the special characters are missing and the space after "]" is missing, too. The header line is "Subject: =?utf-8?b?W1Rlc3RsaXN0ZcOkw7xd?= =?iso-8859-1?q?Umlaute=E4u=FC=F6?="

Does anybody have ideas where this could come from?
