Setup: Exchange (sbs 2011, telecom business adsl (static ip, port 25 opt out)

Previously the only way I could send exchange mail to Hotmail, live, msn , outlook, windowslive was to forward all mail to these domain to a smarthost (which happened to be smtp.xtra.co.nz)

Now with the recent SMTP change can someone from Telecom confirm if anything has been done to have these blocks of IP's removed form the MSN, Hotmail etc block lists? so we can send to these domains direct?

Consumer grade blocks are usually put as that on the spamhaus (I think it is anyway) list. You may need to go to their website and request an opt out for your specific IP

You will need to set up your server much better for outgoing email.  Talk to your IT guys.

You can always use a third party SMTP service such a smtp.com or dyn.com.

The mail server is setup perfectly... the problem is our Telecom Static IP address is blocked by Microsoft (not jusdt our single IP address but entire Spark/Telecom IP Blocks)  but smtp.xtra.co.nz is not blocked by Microsoft, hence we have been forced to use that.

Dont see why we should use a paid service - What I was after was some response from Telecom about what they were doing taking steps to have their IP blocks unblocked by Microsoft.

Telecom/Spark seems to be suspiciously quiet ...

Unfortunately, that's your only option if you want to stick with Spark.  More an "internet access provider" than an "internet service provider" - from a consumer point of view I think DNS and DHCP are the only services still running.

 

I use my own domain for email, so have ended up with about 40 email addresses that I frequently send from (unique per mailing list, for example).  If you have more than 10 (Yahoo's limit) email addresses that you want to use as your "from" address, you have 2 options:
1) Pay for a third-party email service.
2) Change ISP.

Spark was completely unhelpful on this issue, and I'm taking option 2. There's only one week to go until the ISP change, and fortunately the SMTP server is still working for me, so hopefully there's going to be no problem.

Spark have correctly listed the IP's as end user IPs, and hotmail are choosing to block direct submissions from them.

Im sure spark can assign you an IP from a different pool if you ask them.

we run our own mail server that send/receives our email and is setup with best practice which is different to your situation where you appear use xtra's mail server to send/receive all of your email. we only relay mail to smtp.xtra.co.nz for certain domains that have been blocked to us due to our Telecom IP address assignment.

if i was you id simply swap to gmail for email - telecom still remain a pretty good "internet access provider" it is just their (yahoo's) email service which blows.

didn't realise this - assumed as we were only a business adsl plan and opted out of port 25 filtering that we would be assigned an ip from a trusted ip block.

so our ip is just from a block that dynamically assigned to any old end user? how can i look that up?

if i ring telecom, what do i ask them to do for us?

At the end is up to the receiving end to trust or not the IP block. If Microsoft decided that public IP blocks belonging to ISPs aren't trustworthy (because of many infect machines spewing out spam), then it's not really a Spark. Unfortunately is the result of people using computers the way they do.

I suggested a third party because it solves, nicely, the problem at hand.

this i understand, but given we pay Telecom for "business class" internet access i dont think its much to expect that we have a "business class" ip address from a "business class" pool.

they're not our IP blocks, they are Telecoms, they should be the ones ensuring that their customers can use them fully.

remember this is a static ip not a dynamic ip....i understand that most mail providers would/should block communication from dynamic pools but we shouldn't be experiencing this problem with a static pool.

if a customer in a static pool starts spewing spam then they should be shutoff until it is rectified - this should be the ISP's job to ensure its network is being properly used so as not to affect the experience of its other customers..

You shouldn't host mail servers on premises, this is normally bad practice these days and providers can't guarantee if a block is bad, good etc.

Why not just migrate over to Office 365 and let them deal with your problem?

If you're on a Business plan you should be eligible for a free static ip which you can request online

And yes spammers are blocked, however, services like Spamhaus block dynamic ip's by default (I believe - Spamhaus Policy Block List (PBL)) so nothing this ISP's do alters that.

Not quite how it works, unfortunately. You will probably be on an Allocated Portable IP, which is standard fare for a 'static IP' allocation on either business or residential connections with most ISPs. Your ISP will likely to be happy to assist with setting up reverse DNS records etc, but managing your spam reputation really is on you. If they help with it, bonus. Yes, even if it's just because you're part of a wider address block that's affected. Your ISP are not the one blocking you.

I'd suggest you contact whoever is listing your IP in their blacklist / spamfilter etc and request they delist you.
