Hi,

I'm using Postfix 2.2.5. My mail to xxxast-uk.com is sitting in the
outbound queue (for hours) with error message:
(delivery temporarily suspended: connect to
mx2.ast-uk.com[80.229.47.244]: Connection timed out)

However, if I check dig I see:

;; ANSWER SECTION:
ast-uk.com. 13471 IN MX 20 mx2.ast-uk.com.
ast-uk.com. 13471 IN MX 10 mx.ast-uk.com.

A quick test shows that mx2 is there, but times out on a telnet to 25.
However, mx is working fine.

Q: How come postfix continuously tries only the highest priority MX and
is never failing over to the secondary MX? How can I make it do so in
this case (clearly mx2 is dead, but not dead enough..)

Thanks

Ed W
