I seem to have a problem with one email address in my mailing list. If I send a normal email to the address it seems to go through properly, also no issues from other email addresses from the mailman list. Here is the status from the postfix mail queue:- Any Clues?
Check your dns settings for that domain, its mail and soa? You can use dig command to check. If that is good, can you share the output of your postfix main.cf, hostname and hostname -f?
This was not an issue prior to reinstalling the server and it seems to be only one email address. I've checked what you recommended and I can't see anything different from the previous installation. Perhaps I need a new set of eyes on things so I'll post the lot here and see if anyone picks up something I'm just not seeing. I haven't blacked out IP adresses etc in the screen shots, as all this information is available anyway via the web SOA:- main cf:- Code: # See /usr/share/postfix/main.cf.dist for a commented, more complete version # Debian specific: Specifying a file name will cause the first # line of that file to be used as the name.

I was asking this because I cannot dig into the said domain using dig polyoz.net.au or dig mail.polyoz.net.au or dig soa polyoz.net.au. I think what appear in your ISPC may not be properly propagated.
I'm in agreement but I see nothing different in DNS from the other 2 sites on the server, anyway here are the results:- Code: ; <<>> DiG 9.10.3-P4-Ubuntu <<>> polyoz.net.zu ;; global options: +cmd ;; Got answer: ;; ->>HEADER<<- opcode: QUERY, status: NXDOMAIN, id: 10811 ;; flags: qr rd ra; QUERY: 1, ANSWER: 0, AUTHORITY: 1, ADDITIONAL: 1 ;; OPT PSEUDOSECTION: ; EDNS: version: 0, flags:; udp: 512 ;; QUESTION SECTION: ;polyoz.net.zu.

Is a website created for that polyoz.net.au? If I typed that in my browser, it will go to https://polyfidelity.org.au. By the way, according the how to your hostname and hostname -f should be the same. I am not in front of my PC but I think you should check your /etc/hosts for that.
Yes there is a simple html redirect on polyoz.net.au that redirects to https://polyfidelity.org.au. it is an old domain we used to use but have found it handy to "keep alive" via rediection From the How to install a Ubuntu 16.10 (Yakkety Yak) Minimal Server -
