Sorry for all these tests -- but a new copy of Declude Interceptor seems to

I don't think so - at least not on purpose. There have been a lot of
odd DNS based things going on today.

I will look into it, but at the moment things seem to be working.

[sniffer] Re: yahoo mail problems

[george kulman]

I have no problems sending email to my Yahoo account at this time.

The mail was received by mta377.mail.re4.yahoo.com at [67.28.113.74] which
DNSSTUFF MX Lookup shows as one of the IP's for mx3.mail.yahoo.com.

If anyone wants to contact me off-list I'll give them a Yahoo email address
that I've been sending to and they can try it from their mail server.
Conversely, I'll be more than happy to send an email to any yahoo account
you've that you can't send to.

George

I’m sorry to post this here but we are desperately

We seem to be having multiple mail servers on multiple networks having
issues sending to yahoo servers for going on 36 hours now

these are a variety of server types on a variety of networks 

telnet on port 25 is usually getting this

keep in mind that some of our servers are having no issues sending mail 

any one else having this issue

Dear Pete,

I sent an E-mail to the Sniffer Community over an hour ago, and it has not 
yet been received by anyone.  I noticed that 2pm was the last "sniffer" mail

Not really much any of us can do unless
someone “has a friend who has a friend”  but it’s a problem
none the less as yahoo also sells their services to host email commercially for
any domain that will pay them

Would you happen to be running Microsoft
DNS server?  I ran into something similar a while back with certain dns
queries were corrupted for domains that used certain extended dns
queries.  It turned out in our case that our firewalls were removing the
ends of the extended dns packets because they were over limit.  Have you
made any firewall changes recently?

Would you happen to be running Microsoft
DNS server?  I ran into something similar a while back with certain dns
queries were corrupted for domains that used certain extended dns
queries.  It turned out in our case that our firewalls were removing the
ends of the extended dns packets because they were over limit.  Have you
made any firewall changes recently?

I had a similar problem 
with Hotmail once upon a time; the details were different, but the remedy was 
the same.
 
I run a caching DNS 
server on my outbound DNS host, so I simply added a DNS zone 
for Yahoo.com on it, and populated only enough MX record information so 
that I could reliably get to just a few hosts.
 
The same dummy zone 
technique could be used here to consistently deliver mail to the same Yahoo! 
mail hosts and therefore their greylisting will work as they 
expect.
 
If you try it and it 
works, please let us know.

  Here’s what we have 
  found so far
   
  Yahoo is grey listing 
  but instead of running a centralized GL database each of their servers has 
  it’s own
   
  A lookup for their MX 
  shows
   
  Mx1.mail.yahoo.com
  Mx2.mail.yahoo.com
  Mx3.mail.yahoo.com
   
  So your server grabs 
  one of these and does a lookup which returns a round robin response for 
  mx1.mail.yahoo.com of
   
  4.79.181.14
  4.79.181.15
  4.79.181.168
  67.28.113.71
  67.28.113.73
  67.28.113.19
   
  Each of which has a 
  TTL of 1800
   
  So your server tries 
  one of these and gets deferred to try again.  It waits and tries again – 
  but depending on your retry frequency TTL may have 
  expired
   
  And so the process 
  starts over with a new MX1.mail.yahoo.com server
   
   
  Not sure if this is 
  all correct but it is the best we can figure out as of 
  yet

I had a similar problem with Hotmail once
upon a time; the details were different, but the remedy was the same.

 

I run a caching DNS server on my outbound
DNS host, so I simply added a DNS zone for Yahoo.com on it, and
populated only enough MX record information so that I could reliably get
to just a few hosts.

 

The same dummy zone technique could be
used here to consistently deliver mail to the same Yahoo! mail hosts and
therefore their greylisting will work as they expect.

 

If you try it and it works, please let us
know.

Here’s what we have found so far

 

Yahoo is grey listing but instead of
running a centralized GL database each of their servers has it’s own

 

A lookup for their MX shows

 

Mx1.mail.yahoo.com

Mx2.mail.yahoo.com

Mx3.mail.yahoo.com

 

So your server grabs one of these and does
a lookup which returns a round robin response for mx1.mail.yahoo.com of

 

4.79.181.14

4.79.181.15

4.79.181.168

67.28.113.71

67.28.113.73

67.28.113.19

 

Each of which has a TTL of 1800

 

So your server tries one of these and gets
deferred to try again.  It waits and tries again – but depending on
your retry frequency TTL may have expired

 

And so the process starts over with a new
MX1.mail.yahoo.com server

 

 

Not sure if this is all correct but it is
the best we can figure out as of yet

Now that I've looked into it further, yes! Our E-mails

I have sent out a few test messages and will report back

Yahoo is grey listing but instead of

Mx1.mail.yahoo.com

Mx2.mail.yahoo.com

So your server grabs one of these and does
a lookup which returns a round robin response for mx1.mail.yahoo.com of

 

4.79.181.14

4.79.181.15

4.79.181.168

67.28.113.71

67.28.113.73

67.28.113.19

 

Each of which has a TTL of 1800

 

So your server tries one of these and gets
deferred to try again.  It waits and tries again – but depending on
your retry frequency TTL may have expired

 

And so the process starts over with a new
MX1.mail.yahoo.com server

 

 

Not sure if this is all correct but it is
the best we can figure out as of yet

That's where the rule was, I believe.  It started over the weekend, and Pete
removed the rule morning or mid-day yesterday.

What particular group, if any, are you seeing them in? The
experimental-abstract (61) category is my main fp problem lately.

Curious,

[Computer House Support]

Dear Pete,
 
Thank you for your reply.  I can confirm that 
based on our initial review, there were few, (if any) false positives as a 
result of the bad rule.  
 
It's great to have your support as well as that of 
the Snifffer community.  
 
 
Sincerely,
 
Michael SteinComputer House

Dear Pete,
 
Sniffer blocked 35,000 messages today, and roughly 
7200 of them were blocked by the 1174356 rule.
 
Do you think many of these were false positives? 
  Do you know a way of searching through 35,000 Imail messages to 
find the FP's ?
 
What would you suggest in this 
situation.

  
  This was not a bad-rule alert or rule-panic situation. Most of these 
  messages were probably NOT false positives. The rule does have a higher rate 
  than is acceptable (so it was dropped), but it doesn't catch every message 
  with an image, and it does catch primarily image spam.
  
  If I felt strongly about researching this there would be 7200 to look 
  through (not 35000) and I would probably only look through those that failed 
  no other tests or were below some very low weight threshold otherwise - that 
  would probably bring the number down into a range < 100 messages (based on 
  what I've seen reported). 
  
  [ Educated guess items: > 80% of content is usually spam. On weekends 
  this number is higher. This weekend there were some new, aggressive image spam 
  campaigns - so the number of spam captured by a rule like this would be higher 
  than normal rather than lower. The rule was essentially in place only during 
  the weekend and only received FP reports late Sun through early Mon and some 
  systems have reported no discernable increase in false positives during this 
  period. 20% of 7200 is close to 150, so the conservative number likely not to 
  be spam in that group is less than that (due to the weekend) so approximately 
  100 seems reasonable. If there are FPs then it is likely they failed no other 
  tests. ]
  
  Hope this helps,

Hello Darin,

Hi Pete,
 
Can you clarify what this .xhdr option is and how we can enable it?  I don't remember anything in the documentation that describes it.  I think there were references to the config file previously, but there was never anything about it in mine.  If you could give an example of how to enable and use the info it would be greatly appreciated.






In your snf .cfg file, un-comment the .xhdr option line:

 X-Headers

# XHeader File Output - When set to On the engine will create a new file with
# each message scanned with the name scanfilename.xhdr that contains x-header
# information that should be added to the message.

XHeaderData: X-SortMonster-MessageSniffer-Rules
XHeaderFinal: X-SortMonster-MessageSniffer-Result

A quick, ok-but-not-very-correct way to add these headers to the message is simply to pre-pend them (copy msgfile.xhdr + msgfile to newmsgfile, delete msgfile, rename newmsgfile msgfile). Technically, X-headers can go anywhere in the header section. By convention they go just before the body. A utility would seek out the first empty line in the message (\r\n\r\n) and emit the contents of the .xhdr file there.

Oddly enough we occasionally get support questions about "what are all these .xhdr files building up in my spool directory" when folks accidentally turn on this option without knowing what it will do ;-)

Hope this helps,

_M

Hi Pete,
 
You're exactly right, but we often get spoiled by 
the high quality of your detection rate.  It's easy to expect perfection 
when it means less work for us .
 
Thanks for all you do to keep the quality so 
high.
