Temporary address resolution failure
« on: May 12, 2017, 06:19:33 AM »
I have a small issue since upgrading from SME9.1 to 9.2 where emails from an internal linux server would normally send me reports and they would always come through to me just fine. However since the upgrade they are no longer coming to me and this is what I see in the log file which is the reason for it being defered.
Is there an easy fix to this or is this the way it is supposed to be now? Not sure if it is a qsmtp issue or what it may be that stops the messages now all of a sudden.

Me, I would change server.domain.local to something that has a valid TLD,

or, alternatively, install smeserver-wbl and work with whitelisting.

@warren: be sure you have no fail2ban running, otherwise, after n failures, the external IP will be banned at firewall level

I did already have the smeserver-wbl contrib installed and updated from testing repo so I just added the email addresses in question to the white list and it all works fine now. Received all the deferred emails as usual.
Thank you for the suggestions, just weird why I didn't have to do that before but regardless it works now and I'm happy.

Best Regards
