Aussie Broadband email problems

OCAU doesn't require an Aussie ISP email any more, so i'd recommend not using one.

 

yeah i changed mine a few years back when it changed.

 

Right!? Power dropping the important questions.

look for yourself all the MX records point to mx1.wide.net.au

Code:

dig aussiebroadband.com.au MX

; <<>> DiG 9.11.3-1ubuntu1.13-Ubuntu <<>> aussiebroadband.com.au MX

So if you want to be using the mail server provided by the ISP, it makes sense to use the settings provided by your provider.

funny that it does say use mail.aussiebroadband.com.au which is what the OP was using.


dig mail.aussiebroadband.com.au
mail.aussiebroadband.com.au. 265 IN A 121.200.0.25

Which points to a totally different IP than they report, it could be a MX relay of some kind?

dig 25.0.200.121.in-addr.arpa PTR
25.0.200.121.in-addr.arpa. 1779 IN PTR mail.aussiebroadband.com.au.


However checking the IPs provides the follow MX servers.

dig 238.142.142.202.in-addr.arpa PTR
238.142.142.202.in-addr.arpa. 3600 IN PTR mx3.wide.net.au.

dig 239.142.142.202.in-addr.arpa PTR
239.142.142.202.in-addr.arpa. 3315 IN PTR mx4.wide.net.au.



Without knowing what the IP that mail.aussiebroadband.com.au resolved to prior to Jul i wonder if it changed? In anycase aussiebroadband should update there website if mail.aussiebroadband.com.au is no longer the smtp forwarder, or they should correct it to be a CNAME for mx3/mx4.wide.net.au which is what i would do.

Yes but that is for mail ingress mail for @aussiebroadband.com.au this could be totally different to what customers are expected to use for outgoing SMTP.

 

ahhh so if you got nothing to hide you got nothing to fear... classic politician wankery

sorry, that doesnt wash in 2020 get with the times.

 

btw if your paying 55 a year for a domain, thats more fool you, nobodies paid that since the 90's

 

Likely.
In days gone by at ISP X ...

multiple smtp, in-MX, pop, imap, and webmail (just restricted axs imap) all behind load balancer to netapp backend "NFS storage"
but we also had an in-MX and smtp server to netapp that was not behind load balancer as a backup in case LB failed, mail still can be sent out and collected, worked really well

 

FWIW, yesterday I had to change my OCAU profile to a web-based email address, in order to regain access

I've now changed it back to whatever@aussiebroadband.com.au which worked fine for the reconfirmation process
