Hi everyone,

i'm having a curious issue with our postfix instance.

It seems it is sending emails to a domain's A record when no MX is found.

Is that standard? If so, can i disable this somewhere?

connect to bikinibottom.com[208.73.211.70]:25: Connection refused
to=<patr...@bikinibottom.com>, relay=none, delay=407, delays=407/0.01/0.15/0, dsn=4.4.1, status=deferred (connect to bikinibottom.com[208.73.211.70]:25: Connection refused)

# dig mx bikinibottom.com
;bikinibottom.com.              IN MX

# dig a bikinibottom.com
bikinibottom.com.       300     IN      A       208.73.211.70


It's a temporary failure on top of that, left to linger in the queue til....

Clue sticks would be appreciated.
