I adjusted my patch for the mailman-2.1.18-1 distribution, since that distribution requires dnspython as well for DMARC support.
I also corrected the lookup to search for MX records. Previous patch was searching A records incorrectly. I also added user friendly error messaging for e-mail addresses being submitted with missing MX records. ** Patch added: "mailman-2.1.18-1_enhancement-1287604_validate-email-address-mx-record" https://bugs.launchpad.net/mailman/+bug/1287604/+attachment/4319642/+files/mailman-2.1.18-1_enhancement-1287604_validate-email-address-mx-record.diff -- You received this bug notification because you are a member of Mailman Coders, which is subscribed to GNU Mailman. https://bugs.launchpad.net/bugs/1287604 Title: Enhancement: Sanity Check Subscribers MX Record To manage notifications about this bug go to: https://bugs.launchpad.net/mailman/+bug/1287604/+subscriptions _______________________________________________ Mailman-coders mailing list Mailman-coders@python.org https://mail.python.org/mailman/listinfo/mailman-coders
