Hi all,
a mail got stuck in the queue with an error message TLSA lookup error for <mx-server1 of reciever>
THe postfix Log contains the following entries:
warning: TLS policy lookup for <email-reciver -domain>/<mx-server1 of reciever>: TLSA lookup error for <mx-server1 of reciever>
warning: DANE TLSA lookup problem: Host or domain name not found. Name service error for name=25.tcp.<mx-server1 of reciever> type=TLSA: Host not found, try again
warning: DANE TLSA lookup problem: Host or domain name not found. Name service error for name=25.tcp.<mx-server2 of reciever> type=TLSA: Host not found, try again
warning: DANE TLSA lookup problem: Host or domain name not found. Name service error for name=25.tcp.<mx-server3 of reciever> type=TLSA: Host not found, try again
The “Email reciver domain” differs from domain of mxServer.
When testing the “domain of mxServer” with https://dane.sys4.de/smtp/<domain of mxServer> all seems to be fine (green:-))
any Ideas what’s ging on?
How can i fix it?
Environment:
Ubuntu 18.04 (Updated to latest)
