Why does exim consider a 4XX response to MAIL FROM: an "SMTP error"?
Why doesnt it recognize that it should defer?
I'll also note that I've see 5XX codes logged as "SMTP error"s as well,
Exim should consider a 5XX code from a remote SMTP host to mean bounce
the message or recipient..
SMTP>> HELO smtp.mydomain.net
SMTP<< 250 XXXXX.com Hello smtp.CNS.net (oak.CNS.net from address
[205.132.48.7]).
SMTP>> MAIL FROM: <XXXXX@???>
SMTP<< 450 defer '<XXXXX@???>',
sender address target 'XXXX.XXX' cannot be verified at this
time: verify_sender(): BIND server failure: Nameserver: Server failure:
Connection timed out. (Try again later)
LOG: 0 MAIN
SMTP error from remote mailer after MAIL FROM: <XXXXX@???>: host

address target 'XXXX.XXX' cannot be verified at this time:
verify_sender(): BIND server failure: Nameserver: Server failure:

SMTP>> QUIT
SMTP<< 221 XXXXX.com closing connection
LOG: 0 MAIN
