Spam via Google? Apparently Google has been hacked by the Chinese for months now


So, much like many other email providers, Spammers try and abuse VFEmail servers by creating thousands of account to use for SMTP sending.  We set daily limits per account, which forces this 'many accounts' issue - but we also have other throttling in place that prevents the Spam from actually leaving our systems.

What's odd is that Chinese spammers have lately been coming FROM GOOGLE.  Now, it's not uncommon for ASPs and other hosting environments to be the source of Spam - just like any email provider, we have no idea what the account holder will do until they've done it. But in this case, the Spam is coming from Google, using the VFEmail accounts for SMTP Auth.  That's really odd, because I wasn't aware of Google allowing that sort of hosting or sending with a remote sites credentials. 

[edit 3/3/14] Upon closer inspection, the DKIM header shows a Gmail hosted domain, 1e100.net as the source.  Google, fix it already.

Here's the relevant line -
Received: from unknown (HELO mail-ie0-f178.google.com) (YXNkLmxva0B2ZmVtYWlsLm5ldA==@209.85.223.178)
  by mail.vfemail.net with ESMTPA; 24 Jan 2014 02:42:16 -0000


According to whois, 209.85.223.178 is a Google IP.  Unfortunately, I'm only getting automated replies to my abuse emails.  So we'll see if this info gets their attention.

Here are the full headers -

Ok does this really mean Google is hacked?  No, it shows there's at least one system at Google that is a spam source, but it could just be a few botnet members. I understand this sort of thing happens to everyone, but frankly, I'm sick and tired of cleaning this shit up.


Update - 3/3/14.   After blocking the above CIDR for a month, the spammers are now using a new one -

I'm using AVG anti virus for a couple of years now, and I'd recommend this product to all of you.
