Package: lists.debian.org Severity: normal Nowadays the big receivers strongly like to base their antispam decisions on domain reputation instead of IP reputation. Signing outgoing mail with DKIM will improve deliverability without adverse effects.
Pre-existing signatures on relayed messages need to be removed anyway because they are invalid after mailing list processing. This will greatly improve deliverability over IPv6 to gmail, which strongly penalizes IPv6 senders not using SPF or DKIM. -- ciao, Marco
