Hi all,
I have installed the firmware 9.306-6 on Friday and immediately after the reboot, the eMails stucked in the SMTP Spool. I have not the exact error message anymore, which was in the details of a stucking Mail, but it helped me to identify the RDNS as the problem. Disabling it helped and all eMails were delivered. Enabling RDNS again, stopped all Mail from beeing transfered.
But the SMTP Proxy logs shows following:
failed to expand ACL string "${lookup dnsdb{ptr=$sender_host_address}
I hope it will be fixed soon!
Kind regards,
D. Pintaric
