Unquarantine messages quarantined as spam

[#1]

Just received a notification that a message was quarantined as a suspected virus.
I think the original msg probably was a phishing scam since it purported to be from nacha.org but clearly was not from that domain.
..but on sending an unquarantine request including the original message text (no attachments) this request was itself quarantined as spam!

Can you clarify what you mean by this? Are you saying that the system released/delivered the original email and it was that which was identified as spam? If that's the case then it doesn't really surprise me and is probably the intended behaviour.

No, I mean that my mailclient reported that the SMTP transaction with relay.plus.net had been terminated with a 552 when sending the unquarantine request. 
Not of any great consequence as I'm reasonably sure the original msg was a forgery, but thought I'd mention it as it was strange behaviour, especially as there was very little spam-like content in the unquarantine request, beyond one obviously-forged email address and the string:  "[-SPAM-] Bill payment canceled".

Ah, I see!
Any chance you can raise a support ticket providing a copy of the quarantine notification complete with headers? If you then give me a nudge here then I'll see at getting this fixed (should be relatively simple).
