Hi, recently upgraded to v0.19b from earlier version but I think we were already running like v0.18. Since upgrade we are now getting undeliverable mail to several of our routine business partners, like Fedex and Future Electronics. ’
Below is the error message from trying to send an email to our @fedex.com contact and same issue with emails to our @futureelectronics.com contacts. Any input on what may be happening? It is greatly appreciated!
This is the mail system at host box.mydomain.com.
