Just recently someone on Postfix mailing list wrote that he ran into this. I also ran into this - without any change on my server whatsoever - about a year ago, even for SINGLE messages sent to ONE Gmail recipient! It lasted about a week and disappeared by itself (however, the semi-permanent problem that all my mails seem to be filed to Spam folder by Gmail did NOT disappear). I'd say it's just "Google doing Google things". Probably nobody even at Google knows why and how... -- Regards, Jaroslaw Rafa r...@rafa.eu.org -- "In a million years, when kids go to school, they're gonna know: once there was a Hushpuppy, and she lived with her daddy in the Bathtub." _______________________________________________ mailop mailing list mailop@mailop.org https://list.mailop.org/listinfo/mailop
