Re: Weird messages from IETF/Google Mailservers (WG: PALS WG Adoption poll draft-schmutzer-pals-ple)

["Andrew G. Malis" <[e-mail]>]

Loa,

There's a difference between email sent to an IETF email list (which uses
mailman to handle email authentication issues by acting as the email
source) and to an IETF email expander like pals-chairs, which doesn't.

When you're using an email expander, the original source of the email
doesn't change, which exposes the email to any issues the original sender
of the email may have. In this case, the issue is that Google is rejecting
the email to pals-chairs because the telecom.de domain apparently doesn't
support DKIM or SPF. This is the same issue as pi.nu.

Cheers,
Andy
