The mailing list for listmasters using Sympa

[address@concealed]

Hallo List,

what causes the message:"Message ignored because incorrect checksum"?
Cant send any mail over the wwsympa since several days.

sympa.log:

What can cause this? We had recent update to new version (curent 4.1.2). 

I check the sympa.conf/cookie for old and new version (e.g.)
old 12345678
new 87654321

so i kept the old cookie for the new version, because if i change im not
able 
to keep logged in wwsympa.



Mit freundlichen Grüßen / Best regards
