Sorry, my bad. I dropped the ball on publish settings, the writing was not visible for general public to see. Apologies.
Anyway, I realized that since I replied to an existing conversation on Nabble.com, it is impossible for a person not seeing the entire thread to get my idea. The thread can be seen here: http://postfix.1071664.n5.nabble.com/disable-ipv6-when-sending-to-gmail-td60672.html It is Wietse's idea to re-write the response code into temporary, so that Postfix will attempt delivery again. My fix was merely an enhancement to an existing solution to compensate the changes on Google's end. To repeat: Add a reply filter into main.cf: smtp_reply_filter = pcre:/etc/postfix/smtp_reply_filter Re-write IPv6 complaints: /^5(\d\d )5(.*information. \S+ - gsmtp.*)/ 4${1}4$2 That re-write regexp will fail again, when Google changes their error message.
