I'm using your idea of dynamically checking the sender's domain name, and this dig statement is doing the job.<br /><br /> dig +short txt _dmarc.$SENDERDOMAIN | grep -i "p=reject"<br /> <br />We've had a feature to put the list address in the From header for a while, but the intent was to make it simple to whitelist the sending address for subscribers of the list.<br /><br />So we've had to tweak things to apply it to all Yahoo addresses.<br /><br />We include the sender's name and email address in the From header, but substitute "at" for "@" so it does not get confused with the list address.<br /><br />In addition, we stick the sender's name and email address in the first line of the body of the message, to clarify who sent it.<br /><br />If you want to see pictures of this, please see http://www.mail-list.com/yahoo-dmarc-solution/<br /><br />mark david mcCreary<br />www.mail-list.cominternet toolshttps://www.blogger.com/profile/06401915577047059098noreply@blogger.com
