No, it's not, it scales linearly. They would just rather the rest of us
pay for it.

It’s a tough problem to solve at Google or Microsoft’s scale. When you’re
sending out tens of billions of messages a day, even a minuscule gap in
accuracy will lead to a lot of spam leaking out.

Now, if only the big email account providers would filter their
outgoing mail too, there would be significantly less spam.

[mailop] [STATE OF THE UNION] Feb 3rd, 2008.. Why is it the bots start up on weekends.

[Michael Peddemors via mailop]

Hi All,

Once again, an update from the trenches, and what our spam auditors are 
seeing...


Last couple of weekends, bot activity took off, mostly LATAM IPs, 
brazilian ISP's who still have not blocked off port 25 on their 
networks.  Hopefully a topic AGAIN at the Lacnic event in Mexico..


Mostly just standard easy to ignore, but the volume is high.
Windows bots..

OVH is once again in the cross hairs, not only because of the hundreds 
of VPS's spamming (vps-d6643448.vps.ovh.ca naming convention) but 
because more snowshoe spammers.  It should be obvious to them that many 
of the clients with different names, are really in fact the same guy(s).


Just different variations of the same names, using .co addresses.

More droplets stood up for phishing at large hosting providers.. pretty 
obvious stuff, but dangerous.


Chinese Cloud provider spammers still at work, but most of those ranges 
are now in RBL's.


More SERVERION (Des Capital) IP space.. how do they keep getting more IP 
Space? Cannot more be done? Not only spam and phishing, but many other 
types of attacks.


SalesForce has a bunch of 'bad customers', pretty obvious fake domains 
related to weight loss, and finances..


Sendgrid STILL keeps sending phishing.. *sigh* lots of IPs

Cisco's Cloud filtering leaking a lot more the last while..

ESP's other than SendGrid leaking more phishing than usual. #itsnotthathard

Too many Government and Enterprise servers with compromised accounts, 
probably due to that targeted Zimbra phishing attack over the last few 
weeks, but sure wish they would reach out more often.


Have a soft spot for protecting government email servers, but usually it 
is simple best practices that would prevent a lot of it.  Just out of 
the box, is not the way to operate.


As for the rest, looking forward to M#AAWG again, it's been awhile. feel 
free to reach out to offlist if you want to meet up.


-- Michael --

PS, Matt (Spamhaus) hope your team is there again, be a nice chance to 
say remembrances.  And nice of you to offer support for all those Cyren 
customers that are affected. I am sure many RBL services will be ready 
to jump in for their customers (Talked to the SpamRats team, they are 
going to do something similar)


And for those Cyren employees, especially our friends in Ukraine who 
already have it rough.. I am sure there will be plenty of companies 
ready to take some of them on.  If you know any, feel free to have them 
connect to me on LinkedIn etc.


Have a great weekend..

I leave you with a "spot check" on which ESP's are being seen the most 
on one of our servers.. in order of highest to lowest.. Not judging the 
good from the bad ;)

Re: [mailop] Cyren

[Ken Simpson via mailop]

Hi everyone,

To help Cyren customers, MailChannels is offering free access to the
MailChannels content filter API, which accurately filters billions of
messages for tens of millions of users and millions of domains within our
transactional email service. 43% of the domains

that use a transactional email service send their email via our SMTP
service.

We have no plans to charge for access; however, commercial support plans
will be available if you need an SLA. We can accommodate any size of
client; however, we are prioritizing Cyren customers who handle at least 1
million messages per month. If you are a very small user, this API is
probably not for you; however, as a mailop user you are welcome to contact
me for free access to our SMTP relay services for personal use.

If you have an interest in using the MailChannels content filter API,
please contact us here: https://info.mailchannels.com/cyren

Regards,
Ken Simpson
CEO, MailChannels
