[Mailman-Users] Text encoding problems

[Christian Buser via Mailman-Users]

Hi all

Mailman 2.2.0 on cPanel

In the last few days, several messages (not all!) showed problems with 
their text encodings.


This means, messages containing non-standard characters, like ä, ö, ü, 
etc. do not arrive properly at the subscriber’s side. Instead of "ä", 
they show "=C3=A4", for example. And at the line end, a single "=".  The 
headers usually contain


Content-Type: text/plain; charset="utf-8"
Content-Transfer-Encoding: base64

which should be correct.

When I look at the "raw source" of such messages, I see a block of 
base64-encoded text. I can copy this text block and insert it in a 
base64-"decoder", such as , I see the 
same effect as in the mail program.


Yesterday, I answered to such a message. And my message arrived at the 
subscriber’s end as base64-encoded text, it was not decoded by the 
recipients’ mail program, although its header contained the same 
indications as above (utf-8, base64).


I checked with several mail programs; all of them just showed the 
base64-encoded block in the mail body.


Does anybody have a solution? Did cPanel change something on its 
Mailman-part? Did cPanel "update" Mailman in the last few days (our 
provider says that such updates are automatic and he doesn’t know if 
there was one)?


Most of the subscribers use Mail from Apple in various versions, but 
there are also some with Thunderbird, Postbox, GyazMail, Outlook (Mac), 
etc.


Please ask if you need more info - I’ll try to answer them.

Thank you
Christian
