My mistake, it's more subtle than that. UA's reverse lookup of your address was
blocked.
"If an email you sent bounced, and included a link to this page, then it was rejected because the receiver has not
implemented URIBL lookups correctly. URIBL uses bitmask responses to indicate a domain being listed. Our Implementation
guidelines <http://www.uribl.com/about.shtml#implementation> provide the bitmask responses. All queries that we refuse,
we return a 127.0.0.1 response to, as bit 0x1 is not used for domain classification. SpamAssassin
<http://www.spamassassin.org> supports the 0x1 bitmask response, and provides a URIBL_BLOCKED rule which will fire if
the query was refused by URIBL. "

Your server won't reply to a reverse DNS query so it's scoring high on the spam
meter.
