Same here:

dnl SMTP AUTH configuration for relaying through server
define(`confAUTH_MECHANISMS',`PLAIN LOGIN')
TRUST_AUTH_MECH(`PLAIN LOGIN')

Using blackholes.five-ten-sg.com:

FEATURE(`dnsbl',`blackholes.five-ten-sg.com',`"Mail rejected - blackholes.five-ten-sg.com"')

Sending a mail with no authentication to my account on the VPS2, I get this
back:

   ----- The following addresses had permanent fatal errors -----
<gstewart@my_vps2>
    (reason: 553 5.3.0 <gstewart@my_vps2>... Mail rejected - blackholes.five-ten-sg.com)

   ----- Transcript of session follows -----
... while talking to my_vps2.:
>>> DATA
<<< 553 5.3.0 <gstewart@my_vps2>... Mail rejected - blackholes.five-ten-sg.com
550 5.1.1 <gstewart@my_vps2>... User unknown
<<< 503 5.0.0 Need RCPT (recipient)


Without changing the configuration one iota, trying to relay a mail through
the vps2:
