Can a Comcast.net email admin please contact me? One of your non-outermost email servers is running an SPF/SenderID filter (so all messages from domains with -all SPF/SenderID records are getting rejected, regardless of sending server). Thanks, Adam Stasiniewicz
Yes, I understand that people who have never worked in a large providers won't get it. Nevertheless, I still think it is a good idea for folks to have separate infrastructure for contacts such as abuse, security, postmaster so they can work even when other groups in a large company make changes to their corporate gateways, routers, etc. Instead of relying on postmaster@example.com or abuse@example.com, which get messed up because a corporate IT person is trying to keep stuff out of the corporate network; you might also consider things like http://postmaster.example.com/ or security@security.example.com which can be routed to its own separate infrastructure.

Sean, What's to get? If a particular error is easy to make (applying a large-system mail policy that fouls up the abuse desk is an easy mistake to make) and there's a relatively easy alternate system design which discourages that mistake (a separate RHS for the abuse desk that doesn't go through the primary mail path is an easy alternate system design) then when the mistake is made, the ROOT CAUSE is the design error (unified mail system) rather than the instant operator error which revealed it. Two errors but only one root cause. It seems perfectly straightforward to me. Regards, Bill Herrin -- William D.

Well, silly of them to [1] run an spf/sender id filter and [2] to run it on an internal mailhost Equally silly of you to publish spf records in this day and age though. Get rid of the record and that solves your issue rather neatly. srs -- Suresh Ramasubramanian (ops.lists@gmail.com)
