[IMGate] alert: maybe DUNNO doesn't work

[Len Conrad]

with this as first line in the file:

/\[[0-9]{2,3}\.[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\]/ DUNNO

giving:

%postmap -q "[206.104.249.2]" pcre:/etc/postfix/helo_hostnames.regexp
DUNNO

... the client was still being rejected by the next line for "helo hostname 
must not contain an IP"

so the HELO should have matched on the DUNNO and exited from this file, but 
postfix appears to keep process the msg in the file's other lines.

I'm still investigating.

any feedback?
