[Mailman-Users] Mailman Digest Content-Transfer-Encoding

[Andrew Miller]

Hi,
We run Mailman 2.1.5 on Mac OS X 10.4.11 Server. Postfix 2.1.5 is the  
SMTP server. A number of our subscribers who are sent digests are not  
able to receive them. The digest messages are bouncing with the error  
message:

Action: failed
Status: 5.6.1
Diagnostic-Code: smtp;554 5.6.1 Body type not supported by Remote Host

Many of these digests are sent with the header Content-Transfer- 
Encoding: 8bit, and I am wondering if this is what is causing some of  
our subscribers to not receive these messages.

Has anyone else here experienced this problem, and is there a way to  
force Mailman to generate digests using the quoted-printable encoding  
instead? Or possibly, is there a way to get Postfix to translate to  
quoted-printable? We have recently migrated to Mailman from a  
different list serve program, and never had this problem with digests  
with the older list serve.
