Hello, I notice,

DKIM-Signature: v=1; a=rsa-sha256; c=simple/simple;
	d=lists.gambas-basic.org; s=default; ....

Don't forget bounces to end-user from postfix & mailman ...
I have already managed mailing lists (postfix & mailman). Normally it is 
not recommended to use "simple" for a mailing list, but "relaxed" 
(relaxed/relaxed). Dkim signature could be corrupted with big lines.

Bye.
