Yahoo and their mail filters..
by Micheal Patterson 27 Feb '09

27 Feb '09

This may be old news, but I've not been in the list for quite some time. At any rate, is anyone else having issues with Yahoo blocking / deferring legitimate emails? My situation is that I host our corporate mx'ers on my network, one of the companies that we recently purchased has Yahoo hosting their domains mail. Mail traffic to them is getting temporarily deferred with the "421 4.7.0 [TS01] Messages from xxx.xxx.xxx.xxx temporarily deferred due to user complaints - 4.16.55.1; see http://postmaster.yahoo.com/421-ts01.html" The admin of the facility has contacted Yahoo about this but their response was for "more information" when they were told that traffic from my mx to their domain was to being deferred. I may end up just having them migrate to my systems just to maintain company communications if we can't clear this up in a timely manner. -- Micheal Patterson

For our userbase with yahoo/hotmail/aol accouts they hit the spam button more often than delete. Then complain they do not get emails anymore from us, then want discounts on a bill of sale they missed. It is a never ending story. ------Original Message------ From: Suresh Ramasubramanian To: Micheal Patterson Cc: nanog(a)nanog.org Subject: Re: Yahoo and their mail filters..

Yahoo did say "complaints". And it can take a very low level of complaints before a block goes into place - especially for low volume (corporate etc) mailservers. Feedback loops are one cure, and another cure is keeping complaint volumes down. * Do you have an unfiltered NAT gateway pointed to the same IP as your corporate MTA? * Do you have any large spam sources in close proximity to you? Like you are colo'd on a /28 and someone else has a /27 or /26 in the same /24 that's emitting tons of spam (assuming colo). Or you have your mailserver hosted on a dsl pool (even a business class dsl pool) in which case your server is an island of valid mail in a large swamp of virus traffic * Do you have a marketing department that might be slightly overactive? etc etc. srs

Internet access using VRF aware NAT
by devang patel 27 Feb '09

27 Feb '09

Hello, Have one question about VRF aware NAT for internet access! If we will enable the VRF aware NAT on local PE to have an internet access via central Internet PE then we will not have connectivity to any other VPN site as all local CE prefixes will be translated to the loopback IP address of the local PE. We can have route map which will match the ACL for specific CE source to specific VPN destination with deny key word and it will prevent the NAT when CE will try to communicate with other CE of same VPN or different VPN. That looks longer configuration in real world right! so is that the only way I have when I will have only one option to configure the locap PE with VRF aware NAT to gain internet access? I need to know what is the implement in real world? How service provider networks are providing internet access with MPLS VPN option? I know about customer is getting VPN connectivity on one router and service provider will give other internet connectivity link which might be terminating on same router or other router. I just want to know which is mostly used option as far as the internet access service with MPLS VPN services! thanks, Devang Patel

We ran into this issue where we where tagging emails with ***SPAM*** and forwarding them on which got us blocked everyone once in a while pretty annoying. Carlos -----Original Message----- From: Chuck Schick [mailto:chasjs@warp8.com] Sent: Wednesday, February 25, 2009 10:18 AM To: nanog(a)nanog.org Subject: RE: Yahoo and their mail filters.. We found this issue to be associated usually with users forwarding email to a Yahoo account. If spam slips by our spam filters and gets forwarded where the enduser reports it as spam not realizing the impact on their actions. In the last couple of years we have been not allowing people to forward their accounts to yahoo, aol, hotmail, etc. Too much of a headache. Chuck

Many of their internal mailing lists, for internal use only, get more spam than actual mail. Just another example of profound extent of deferred maintenance that handicaps so much of what Yahoo does. Their new CEO knows this and is capable of addressing it. Look for changes soon, mostly to mid-level managers hired during the Semel years, managers who failed to keep their technical skills up to date. Roger Marquis
