err, wait, are you giving a 4xx in reply to DATA?
that is invalid.
At least for 451 and 421 replies, it sure seems legal to me. To quote RFC 2821:
4.3.2 Command-Reply Sequences

In addition to the codes listed below, any SMTP command can return
any of the following codes if the corresponding unusual circumstances
are encountered:

421 Service shutting down and closing transmission channel
Specific sequences are:
DATA
I: 354 -> data -> S: 250
E: 552, 554, 451, 452
E: 451, 554, 503
