Can't receive meeting requests
Email goes back and for the between the two domains all day with no problems as do meeting requests from X to Y.....just not the reverse.
Senders on the Y domain get this error message:
The e-mail system was unable to deliver the message, but did not report a specific reason. Check the address and try again. If it still fails, contact your system administrator.
< (mail server name for Y) #4.0.0 X-Postfix; lost connection with (X mail server name and IP) while sending MAIL FROM>
We are baffled! This problem started abruptly. There were no changes in this domain but we believe that domain Y started using CAC cards just a few days after we got out last received meeting request from domain Y.
Any ideas? we are desperate!
