Dear common-lisp.net users, mailing list owners,
You're receiving this message because you're listed as a mailing list owner or because you have a common-lisp.net login account. If you have different mail addresses associated with both, you may get multiple copies. Apologies for that in advance.
We're sending this mail to announce policy changes intended to be executed as of March 15th regarding mailing list setup. [For further discussion, please direct to clo-devel@common-lisp.net.]
Changes to mailing list headers and footer ==========================================
Google is tightening their DKIM validation; most of our mailing lists cause invalid DKIM signatures on out-going mails: * Adding the Subject prefix '[<mailing list>]' invalidates the DKIM signature of the original sender * Adding the e-mail footer may invalidate the e-mail's DKIM signature
Since Google, Yahoo! and other big mail providers are moving to signing their outgoing mail, the percentage of invalid mail sent by common-lisp.net increases. This hurts our reputation as a mail sender and has led to problems with Google accepting common-lisp.net mail. (Admitted, DKIM was not the only reason.)
Due to the above, we will change the mailing list setup for all mailing lists: * No longer add the mailing list subject prefix * No longer add the mailing list footer * Add the List-* headers as per RFC-2369, filtering of mailing list messages can be done using these fields
Change to moderation expiration ========================
Additionally, we've found that many mailing lists have been set to not expire mails in the moderation queue, resulting in a moderation queue of 10-thousands of mails some more than 8 months old. Recognizing most of these mails are probably not being moderated because they are spam, we intend to change all mailing lists which do not expire their moderation queue to expire moderation requests after 90 days.
Again, the above is an intended policy change. Please send feedback on clo-devel@common-lisp.net.
Kind regards,
common-lisp.net admins
