I would not trust too much error messages from Google, and there is a possibility you cannot do anything at all. It happened once to me that I ran - "out of the blue", for unknown reason - into getting exactly the same reject message from Google while sending 4-5 messages IN TOTAL PER DAY to Google. Eventually, after 10-12 hours, the messages got through, but then the same happened again with any (even a single) message my server sent to Gmail. After about a week the problem has "magically" gone. This is Google. It behaves unpredictably, there's no clear explanation why, there's nobody to contact who can help you (even if you manage to get contact with a real human involved into mail handling at Google - as I was lucky to do - they usually can't do anything about your problem). However, stopping forwarding mail to Google seems to be a reasonable thing. They don't like forwarded mail. If you must forward to Google, use some software that does SRS (sorry, I can't recommend anything, but I'm sure someone else on this list can). -- 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." _______________________________________________ Postfix-users mailing list -- postfix-users@postfix.org To unsubscribe send an email to postfix-users-le...@postfix.org
