Re: [PATCH] Handle unreachable host in address verification as 200
Since people keep asking for this, I implemented the following
Incompatibility with snapshot 20080428
Postfix SMTP server replies for address verification have changed.
unverified_recipient_reject_code and unverified_sender_reject_code
now handle "5XX" rejects only. The "4XX" rejects are now controlled
with unverified_sender_defer_code and unverified_recipient_defer_code.
Major changes with snapshot 20080428
Finer control over the way that Postfix reports address verification
failures are reported to remote SMTP clients.
- unverified_sender/recipient_defer_code: the numerical Postfix
SMTP server reply code when address verification failed due
to some temporary error.
- unverified_sender/recipient_reject_reason: fixed text that Postfix
will send to the remote SMTP client, instead of sending actual
address verification details.
