Well, since it's not actually bouncing and just being deferred, that's not too
bad at least. It does seem to fail often enough however and I've been ripping
my hair out trying to figure out why.
I do have MX, SPF and RDNS records for everything.
okay I give up, I dont know what else to suggest you. what I told you
before resolved my problem. maybe others have another experience about it.
I am just curios, you said this is new QMT server, are you build it
using qmailtoaster's install script or QMT-ISO ?
if you are using QMT-ISO you need to change several qmail's control file
other than localhost
otherwise your server's IP will be listed on cbl.abuseat.org (like me
before) and perhaps Yahoo/gmail/hotmail use CBL
