Have clients who have contacted me to say their emails sent to other people, are bouncing back to them, with the message that they have been detected as junkmail by RBLs

Done a check at MXTOOLBOX, and yes telecoms IPs are listed on a lot of RBLs

Your clients should use a professional SMTP and not an ISP service. I see you posted about this happening with Vodafone in another thread.

It would be a lot more valuable to your clients to have a hassle free experience even if it meant paying a few dollars more per month (an Office 365 Exchangeo only plan costs $6.10 a month).

These are people using their free ISP email service, eg @xtra.co.nz, and I doubt they will want to pay xtra for something they are already paying for. It isn't my clients who are getting the emails bounced back, it is people who are sending them the email. My clients can't receive the email from xtra users, because telecoms mailserver IP is blacklisted on RBLs. My own clients do use proper SMTP servers so there is no problem at their end, and I never have any problems with their own emails bouncing.

I think it is a universal problem with NZ ISPs, as snap also were blacklisted a few weeks ago. Maybe ISPs should stop providing email. The problem is if something is free, then people will use it, and expect it to be reliable.

But that contradicts what you said in the first post, doesn't it?

Even if it's free, a business that advertises @xtra.co.nz, @hotmail.com or @gmail are just not professional enough in my opinion. Perception is part of the business image they want to project.

And as noted your topic is about Telecom servers being blocked but then you say is the other way around...

The problem is I am getting contacted by both parties, both the sender, and the person trying to receive them, and they are both trying to work out where the problem is. I have told the sender to contact telecom, as their IPs are the ones blacklisted in RBLs, as was shown in the bounced back emails they received from the RBL. Perhaps I shouldn't have intially referred to the sender as my client, even though I am trying to help them, that is perhaps where the confusion is.
However my client is also a telecom customer, and also has the same problem when sending from their home xtra account, to their business domain email account.

They are telecom customers, who probably have little knowledge on where to go to get this sort of problem fixed. It must be frustrating for them too, to experience this type of problem with emails that they send to people bouncing back due to being detected as junkmail, and I am not sure how helpful telecoms helpdesk is when reporting this type of problem.

These are probably home users sending the emails, so they probably don't care about the domain extension and professionlism. They probably just don't want to pay for something more. I would recommend they just use gmail instead, as gmail doesn't seem to get listed on RBLs, and they probably don't have the same types of problems that ISPs have that cause ISP IPs to get blacklisted.

No reply from any one from Telecom about the problem?

100% correct.
You have to wait for the issue to sort itself out.
try telling that to your client & watch their reaction, thats the hard part .
I often come across small/medium companies still using xtra as their primary email a/c .
Lawyers, accountants etc will have many many clients using xtra/gmail/hotmail & they do have some issues sending/recieving to these 'free' email a/c's

But, if the senders ISP is blacklisted, the receiving end (your client) should have control over this blacklisting if its a professional quality email service .

Also : for clients with a xtra email a/c: the xtra/yahoo spam filter has gone off the rails. Its blocking all sorts of valid emails . I have a xtra home email a/c & the amount of valid email the spam filter gobbles up is now getting ridiculous. No biggie IF you know how to get around this, most will have no idea. There is a setting in webmail that forces anything in the spamfilter to be downloaded via the usual pop3
It seems xtra/yahoo have no idea about whitelisting some of the most common NZ email addresses

1st thing to do is use webmail & check whats in the spamfilter
