9.306-6: Bug with RDNS and stucking eMails

dpintaric
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

    This could be a problem with external DNS, not internal.  Depending on how you have things configured, you might see evidence in the UTM DNS Proxy log.  For some reason, you don't appear to be able to get rDNS - if you haven't made any changes in DNS, maybe your ISP's network has a problem.

    Cheers - BOb

    I have to repeat. DNS works. If DNS won't work, no eMails could be delivered.
    I am using 4 DNS, two of them of the data center provider and two of the carrier Level3. All are reachable and do answer. It is not logical that all of them don't work correctly.

    Running for one year without problems, with installing every firmware and restarts. Now installed the new firmware did the restart and immediately the eMail were not processed anymore. Why not accepting, that there is bug in the firmware?
