Second, there is no restriction in using it as part of a
continuation line.  Example:

     C: DATA
     S: 352 Begin sending your data
        [client uploads data]
     S: 150-DKIM signature found!
     S: 150-Please wait while we process your DKIM message!
     S: 150-Waiting for trust server to respond...
     S: 150-Still waiting for trust server to respond...
     C: 550-Sorry, The DKIM POLICY has failed this transaction
     C: 550 Please see

Perhaps off topic, but it seems that sendmail uses 0xx
with similar way if VERB command is given

250 2.0.0 Verbose mode
MAIL FROM:<hurtta(_at_)localhost>
250 2.1.0 <hurtta(_at_)localhost>... Sender ok
RCPT TO:<root>
050 <root>... aliased to hurtta
250 2.1.5 <root>... Recipient ok

But note an important difference: There is no "-" after "050", so the
RCPT command returns two results (050 and 250) in this case, not a
single result with conflicting return codes. LMTP and draft-hall-prdr
extend the data command in a similar way.
