One simple reason is that sending mail over IPv4 require an SMTP-relay (because port 25 is blocked, or similar), while IPv6 does not. I thought that Courier would use AAAA records in favor of A records? I noticed that when sending to gmail Courier is not using AAAA any more. Perhaps I have another error in my config? Did perhaps this change in a recent Courier? ~A ------------------------------------------------------------------------------ _______________________________________________ courier-users mailing list [email protected] Unsubscribe: https://lists.sourceforge.net/lists/listinfo/courier-users
