BarTender: I'm personally surprised anyone in this day and age needs port 25 unblocked.

You should be talking to your mail server over SSL so 465 or 587 would be the ports you use to connect so having port 25 blocked wouldn't impact you at all.

Having inbound port 25 means you are leaving yourself open as a spam relay. That's just bad (TM).

I talk to my mailserver on using TLS on port 25. STARTTLS.

I also run my own mailserver at home as a backup for my primary MX. So I like to have incoming open.

Yes, I realise people running their own mailserver at all, let alone at home, is probably not common, but this is The Internet which was designed to be open and free, so I think it's good people/ISPs still offer a way for that to be the case.

We're not all bumbling idiots who don't know how to filter mail.

Audiophiles are such twits! They buy such pointless stuff: Gold plated cables, $2000 power cords. Idiots.

OOOHHHH HYPERFIBRE!

Mail servers generally talk to each other on port 25
Less popular is port 587
But port 25 is the important one.

The issue with this sort of complaint is usually a person or business running a mail server that needs to deliver mail to mx destinations on port 25 - ssl isnt usually avaliable for these sorts of connections.

So get a business broadband plan.

Or better yet get your own vps as they are cheap as chips and host your mail there.

That way you can turn your pc off and save power.

I'm yet to be convinced inbound or outbound port 25 is needed on a consumer connection in this Internet of things day and age.

I reckon the days of needing a block are past. Just PBL the dynamic ranges and ignore complaints. Anyone dumb enough to take email from a connection in the PBL and without matching DNS to the helo etc deserves to get it.

could it be that someone is wanting to use a home internet a/c for business use ??
:-)

or could be an old copier needing port 25 for the scan to email function.....

Im sure port25 is blocked by default, because out of control spamming from infected PC's might get Spark IP's Blacklisted

Talkiet: Well, time to correct myself.. Thanks to CBRpilot who works more closely with the subscriber features than I do... There apparently have been a number of changes quite recently...

- The unlimited plans do allow static IP (I think at a cost) but DO NOT allow Port 25 unblocking. (That's the odd product limitation wiggle room I gave myself before)

Cheers - N

Wow that is great news! Does anyone know if this is the correct form to use to request one? http://www.spark.co.nz/business/shop/webservices/staticipaddresses/

(I ask because the list of plans there looks fairly old and dosen't include Fibre.

That is the correct form... For fibre unlimited, use "Home package unlimited" in the dropdown. The price is $15/month.
