I've been getting them a lot and from mail.ru...

I sent a complaint to their abuse email and here's the response:

Dear Jason:

Thank you for contacting Cashette. We are an anti-spam email provider. Most
of the accounts reported to us are not valid email addresses. If you send us
your list, we will check them out. If they are valid accounts, we will close
them.



Please note these are spammers, who registered with you at the same time
they registered on our site or not even bother to register on our site at
all. We have no more control over them than you have.



We have a strong system blocking out-going spam. However, in this case, the
spam was not sent from our site. It was posted directly on your site. It is
originated from your site. So only you can block it so neither you nor us
can be their victims. You should review all your postings before allowing
them to be posted. At the minimum, you should use keyword blocking or more
sophisticated spam-blocking system. By not doing so, you are enabling
spammers to spam your users and damage our name.



Your lack of spam-blocking/site security is the cause of the problem. It's
only a matter of time when the spammers take advantage of your
vulnerability. Blocking any domain will not solve the problem since the
spammers can arbitrarily choose any free email domain to register with you.


Sincerely,
Cashette Anti-Abuse
