Thanks so much! I discovered that messages that are using one character set (charset="windows-1251") are appearing correctly and messages that are using another character set (charset=iso-8859-1) are not appearing correctly.
Is the only fix for this for the list members to use the character set which is appearing correctly after mailman processing?
Sorry for not answering sooner. This one got buried in my inbox.
Those users who are sending charset=iso-8859-1 need to do something different in their MTAs or with the setup of their computers. The iso-8859-1 character set is also known as Latin-1 or western. It does not contain encodings for cyrillic characters. The ISO character set with cyrillic characters is iso-8859-5. Windows-1251 is also a cyrillic character set.
See for example http://czyborra.com/charsets/iso8859.html for descriptions of the various iso-8859 character sets and http://czyborra.com/charsets/cyrillic.html for various cyrillic character sets.
Apparently your problem users are using a cyrillic setting on their computers so that they type and see cyrillic characters on their displays, but their MUA's are mis-identifying this as iso-8859-1. This is basically a setup issue on the sender's computers.
