OK thanks, that's interesting I will try. It also got me thinking, is there a way to follow a "best effort" approach? As in, at first try to send the mail directly and only fall-back on failure to the second MX. This will make it so the setup is somewhat less reliant on the second MX (whose uptime I cannot guarantee as much as the first). -- Kind Regards, Wael Karram.
