Self-Hosted Mail Server

Good day!

I've just recently joined Optus and it's my Day 3 now and I have a very horrible experience so far.  Prior to Optus, I was with Telstra, both on Cable internet system.


A bit of a background:

  • I have been using an OS X server to host my e-mail.  I have my own domain (which is my last name), and my e-mail address would be "".  As I am with cable, it means my IP address is dynamic. To solve this problem, I use DYNDNS to manage my domain and IP. So ig my IP changes, DYNDNS would just update the DNS servers automagically.
  • For the last 8 years, I never had any problems until 3 days ago.

Trouble with Optus:

  • Prior to signing with Optus Cable, I have asked the representative all questions that I need to ask to ensure that Optus would be able to provide what I need. The representative said that by default, Optus closes its port 25 (SMTP), but can be opened.  I was asked a few questions to make sure I abide with the Fair Go policy, and it was deemed that I am because I don't use my e-mail for business.
  • Then, I signed up for Optus. E-mail system didn't work. I contacted Optus to open up port 25, which they did.  Now I can send outgoing e-mail.
  • Sad to say, for the last 3 days, I haven't got any e-mail as they haven't opened up port 25 for incoming.
  • I spent the last 3 hours with someone from Optus' overseas tech support to no avail.

Can anyone please shed some light on this?  Just want to make sure that before I switch back to Telstra, that it is really not possible for Optus to accommodate my request.  That, of course, I'll seek the advice of Telco Ombudsman as well.


Warm regards,

Re: Self-Hosted Mail Server

I sent you a PM, Casey.


Just for the record, if this is not resolved by COB Wednesday, I will terminating all my Optus Services that I’ve signed up for last Friday and will not be expecting any costs.


I will also seek compensation for the third party services that I need to purchase to enable incoming e-mail on my system as an interim. Your overseas support team is full of empty promises as they have only returned my call once and would refuse to provide me a callback number.


I have been advised by the Telco Ombudsman that all communication with Optus be written.
