Second, there is no restriction in using it as part of a
continuation line. Example:
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 http://trust-r-us.com/msgid=123213123
Who knows? Is this not possible? It is out of the whelm of
No, it is is clearly not impossible. However, it raises two
issues in addition to the one about the codes all being the same
which, IMO (and in the text of 2821), arises from one of them.
Perhaps off topic, but it seems that sendmail uses 0xx
with similar way if VERB command is given
250-Hurtta06k.keh.iki.fi Hello localhost [127.0.0.1], pleased to meet you
250-AUTH DIGEST-MD5 CRAM-MD5
250 2.0.0 Verbose mode
250 2.1.0 <hurtta(_at_)localhost>... Sender ok
050 <root>... aliased to hurtta
250 2.1.5 <root>... Recipient ok
( Seems that http://www.iana.org/assignments/mail-parameters
lists VERB )
1xx was not selected for that usage. So 050 is really used,
but is 150 used on somewhere?
