Hello postfix world, I seem to be receiving all of my emails excepting some from people who have emails with yahoo email acounts.They are either taking up to 20 hours in yahoo's queue or being returned.
The postfix is a spam filter (amavis/clamscan/SA) for an exchange forest of 55 users, not many, so not much of a load. I am not getting any reports from other legitimate domains sending us emails having this issue. I have tried a bunch of things found on the internet, but the errors still exist. This was not a problem on my prior filter build on postfix 2.2.10. I had generally ignored such errors as my thinking was that these were caused by poorly designed bots, that may be a mistaken assumption with this more current postfix. I am thinking that there is more controls that I might be missing. So please find below an error from a client at yahoo, examples or the errors in postfix logs and my postfix -n output. Thank you for any help or insights that you may have! Eric Client errors are like this, Sorry, we were unable to deliver your message to the following address.
