Personally I don't think the "try MX first" is a good strategy.
Hi Anton ... am enjoying watching this thread. :-) Just a quick couple of comments here (from my work) ... I recently published a website by simply changing the A record IP address and was bitten by the Implicit MX rule: http://www.openspf.org/FAQ/Implicit_MX_rule Not explicitly designating mail exchangers effectively locks the routing of mail to the A record IP address. If you have no mail services running there, the sender will retry until the defined permanent delivery failure state is reached and sending just fails. At least, this is my experience. regards, Carl -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org
