I dropped the TTL on the MX, SPF, DKIM and DMARC records to 300 about 36 hours before starting the migration, and published the new DKIM key as well. I left the records at 300 for about 72 hours after the migration and then moved them up to 3600. -- Paul Waring Freelance PHP developer https://www.phpdeveloper.org.uk _______________________________________________ mailop mailing list mailop@mailop.org https://list.mailop.org/listinfo/mailop
