[Mailman-Users] German umlaut in From-line using outlook exchange with closed lists

[Werner Spirk]

Mails sent from outlook exchange will not be sent to a closed list
when there is a German umlaut within the name like

From: =?iso-8859-1?Q?Mai=2C_G=FCnter?= <Guenter.Mai at lrz.de>

in general:

Mail sent
From: =?iso-8859-1?Q?Surname=2C_Givenname?= <ADDRESS at lrz.de>

causes an undeliverable message by mailman sent to
surname at mailman.lrz-muenchen.de, if the list in a closed list:

with the content like:

It is not allowd to you to send mails to this mailing list because
you aren't member of the list.

Outlook Exchange goes conform with RFC 2047 .


Is there any patch for this problem?

Thanks in advance
