Yes, it's an IronPort.
Their support says:
Section 4.5.3.1 of RFC 2821 (4.5.3.1.10 in RFC 5321) recommends to treat
a 552 response after the RCPT TO command as if it was actually a 452
response. This behaviour was intended for cases where the number of
recipients exceeds the MTA's limits, and the idea was that the sending
MTA should requeue the extra recipients.
Section 6.4 of RFC 1870 contradicts this, and explicitly says that a
552 response must not requeue the recipient. This is intended for cases
where the message size limit is imposed on specific recipients.
So generally, the smtp response code 552 can be used for multiple
incidents, like the recipient count and also for the message size. In
order to address this kind of issue on the Email Security appliance, we
have logged a 'defect' with number ...... "Per-recipient rejection based
on message size in response to a RCPT command", and our engineering team
is working on an implementation which works in all cases that all
messages get soft or hard bounced correctly without any issues.
