Hi, I googled this question, but was not able to find a definitive answer or solution. I am using Postfix 2.9 and I'd like to block or redirect (to our original sender or at least /dev/null) outbound emails destined to fake domains (user typos) like gmail.ru or/and potentially stop sending to *@*.ru addresses all together. The latter would work just fine for us :)
Can anyone please help with a solution? Sincerely, Kristjan
