Hello there, Is there an option to select MX type order for outgoing messages (IPv4 first, then IPv6, or vice versa), and/or entirely disable IPvX usage for outgoing sessions?
For example, I have a bunch of machines that don't have IPv6 support, so while sending mails to @gmail.com 'smtp-out' always starts from IPv6 MX which produces only faulty connection attempts and wastes time. I haven't found an option in program to force IPv4 using. More general: is there an option in global scope which controls allowed protocols? --- wbr, Denis.
