The verification probe is succesfull but the receipient gets rejected. Test with mail address in lowercase works. Before with Postfix 2.11 everything was fine. Now i have a new mailserver with Postfix 3.1.4 that acts like described. Hope someone can help me... -- View this message in context: http://postfix.1071664.n5.nabble.com/Strange-behavior-Postfix-3-1-4-address-verification-tp91564.html Sent from the Postfix Users mailing list archive at Nabble.com.
