Ditto. They appear to use some strange form of greylisting combined with blocking. What seems to help is SPF and PTRs that match the EHLO your MTAs will send. We didn't implement Domain Keys / DKIM. On a related note, don't get me started on Hotmail. They used to (still do?) silently swallow mail into a black hole after accepting it. No NDR, no spam folder, just good ol' mail shredding without anyone knowing. Again, SPF and PTRs seem to help. Oh yeah, make sure you're not sending spam to them. That might help too. ;) Erik ________________________________________ From: Joe Abley [jabley () hopcount ca] Sent: Tuesday, February 24, 2009 9:41 PM To: Micheal Patterson Cc: nanog () nanog org Subject: Re: Yahoo and their mail filters..

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?
Yes. Everybody else. Joe
