Too much spam passes Astaro since v8

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?

  • As you can see, that word doesn't get filtered here, either.

    PS I'm seeing no change in the number of spams getting through.

    ****** LOL [[:D]][[:D]]


    PS I'm seeing no change in the number of spams getting through.

    In my case the number of quarantined spam is decreased respect to v7 (the spam rejected during smtp transaction is increased) so, in my case, spam filter of v8 works much better...
  • The most obvious spam passes the Astaro, for that reason we operate a Sonicwall emailsecurity server behind our Astaro for nearly 5 years. Looking at the Sonicwall reports we see no increase/decrease in spam that passes the Astaro after we've upgraded to 8.202.
  • Herman,  What spam are you seeing get through the CommTouch engine that Astaro currently uses?  Since the change to that in V7.3 (August 2008), about 97% of spam is quarantined/rejected in the sites where we have Mail Security.

    Hello Bob,

    All kinds off spam, Casino's, Slots, Poker, loan proposals etc.  Most of them are identified as spam on ip reputation by the Sonicwall server but also phishing mail passes the Astaro and gets filtered by the sonicwall machine.

    on an average day about 100 spam e-mails would slip through the Astaro to about 125 users. In combination with Sonicwall, users won't receive a single spam message in weeks or months. The downside is that i have more false positives.

    Herman
  • What anti-spam settings have you configured in your Astaro on the AntiSpam and AV Tabs (screenshots will be quicker than typing them all out)?  I've found, with the correct tuning, that Astaro catches in the high 90th percentile of garbage.

  • Today I got my next Spam-Mail for the "Nail blue-wonderpilz with u to insure ur potence!" [:@]

    @all What RBLs you are using?
  • Show the lines from the SMTP log when that email was passed.  Also, show the header of that email.  Remeber to obfuscate your IPs like 84.*.*.84.
