Re: problem with recipient address verification

[A. Schulze]

wietse:

If it is DATA, then address verification is possible but it requires source code

changes to Postfix:

- After successful RCPT TO, do not assume that the recipient exists,
  but send DATA and disconnect after the DATA response is received.

This will cause extra noise in the logfile, therefore it should be
configurable:

- Configure what sites reject recipients after DATA.  The list of
  such domains is limited, so this is not a big burden.

this would be indeed a useful extension...
