Too much spam passes Astaro since v8

tomtomtom
I realize that too much spam passes the Astaro since (I think) v8.200.

Today I got a mail with the word "vagina" in subject. Do we need to care about expressions now? We never had to care about expressions in the past, so we don´t have any word on the expression list until now.

What´s wrong there?

We use "Reject invalid HELO / missing RDNS", "Greylisting" and "Perform SPF check" and the following RBLs:

bl.spamcop.net
psbl.surriel.com
cbl.abuseat.org
dnsbl.ahbl.org
dul.maps.vix.com
rbl.maps.vix.com
blackholes.mail-abuse.org


What else can we do?

    I know the DNAT would work.  A Firewall rule using the "(Address)" object created by WebAdmin might work: 'Internet -> {ports 25 & 465} -> Additional Address (Address) : Drop'.  Does that work?

    Cheers - Bob
