spams from Google Groups

Hi all,
   Every day my company receiving a huge amount of spams coming from sender "mahmod rmdan  "
When I check Astaro mail manager I see these mails coming from a lot of Google Groups mail addresses like:
alshomou+bnccni9tistehcm0jp5bboeugfbnw@googlegroups.com

noorislamna+bnccotz7a6xbhcgnpt5bboepljibq@googlegroups.com
noorislamna+bnccotz7a6xbhcgnpt5bboepljibq@googlegroups.com
kalam-fyel7op+bncclnyoywnexcfvjl5bboepxivbg@googlegroups.com
panat-3man+bncclnyoywnexcevjl5bboerw215g@googlegroups.com

panat-3man+bncclnyoywnexdqupl5bboeydrnjg@googlegroups.com

noorislamna+bnccotz7a6xbhcewyn5bboedtewra@googlegroups.com
noorislamna+bnccotz7a6xbhcewyn5bboedtewra@googlegroups.com

and every day I see different mail address like the above.
How can I stop these spams?
Thanks,
Mostafa Aly

  • Mostafa, I just tested, for example, with test*@gmail.com blacklisted.  It did not block an email from testuser@gmail.com.  Only when I put testuser@gmail.com in the blacklist was email from that user blocked.  I don't know if this is a bug or a feature request.  You should submit a support request to Astaro to have that clarified.

    If you believe that someone is targeting you, you should complain to Google, sending them a copy, with headers, of each of the emails.

    Good luck, and let us know what Astaro says.

    Cheers - Bob

  • Maybe you can use a regex like test.*@gmail.com - it's just an idea - no experience with it.

  • I don't think that uses regex, but it would be a happy surprise if it does!

  • Dears, 
    When I try to send a complain to google about these groups , I surprised that all the above groups does not exist!!!!!
    what is your opinion.
  • As per Astaro support "Only full domains can be blacklisted with wildcard"
    and there is no plan to add the feature of wildcard subset of email account like "dfs*.googlegroup.ocm yet.
    So  added a feature request under subject of  "Adding wildcard flexibilty to smtp proxy blacklist".
    Thanks,
    Mostafa Ahdy
