The mailing list for listmasters using Sympa

[Miles Fidelman <address@concealed>]

Folks,

It does not appear that simply stripping off DKIM related headers solves 
the problem with Yahoo originating mail, at least when sending to users 
on systems that look for DKIM signatures. Essentially such end systems - 
like Yahoo itself, gmail, hotmail, Comcast - lookup Yahoo's DKIM records 
(stored in DNS) which contain Yahoo's DKIM policy - which is "reject 
anything without a properly validated DKIM signature.  So... something 
that has a From: <user>@yahoo.com, routed through Sympa, WILL bounce 
from such systems.

I notice that the mailman development team, and a few other list package 
development teams, are rapidly coming up with patches to address the 
issue (note of the solutions are ideal, but they work). Can any of the 
Sympa team comment on whether the issue is being worked?
