Emails not being delivered...

[K0608]

Can anyone shed any light on this please? We've recently moved hosts, and I think that by and large, so far, so good, however, I tried to send an email to a few people the other day (10 BCC recipients or so), and got this back:

This message was created automatically by mail delivery software.

A message that you sent could not be delivered to one or more of its
recipients. This is a permanent error. The following address(es) failed:

"someone's email address here"@btopenworld.com
host mx.bt.lon5.cpcloud.co.uk [65.20.0.49]
SMTP error from remote mail server after pipelined MAIL FROM:<[email protected]> SIZE=7865:
522 email sent from 184.154.58.229 found on industry IP blacklists on 2017/12/02 18:29:29 GMT, please contact your mail sending service or use an alternate email service to send your email.

I checked to see whether our IP Address was listed on any of the email black lists, and it's found on Backscatterer. Our hosts say that it's nothing to worry about, but if we're getting emails bouncing from @btopenworld addresses, probably amongst others, then it's surely a problem. It looks like this blacklisting on Backscatterer will expire soon, so should that help things?

Could anyone shed any light on this please?

Could you check this site: https://mxtoolbox.com/SuperTool.aspx?action=blacklist:184.154.58.229&run=toolpage

Your ip address is blacklisted as spam

Go to mail-tester.com and send an email to the address they give you.

You will get a report that will tell you whether the blacklisting is the only problem, or if there are other things.

You can request removal from http://www.backscatterer.org/index.php?target=test

Is it a managed service? If so, insist your provider makes more effort to resolve the issue, e.g. delisting where necessary, talking directly with BT postmasters or rotating the IP address(es) being used for outgoing delivery.

Thanks, that't how I found out that our IP was blacklisted on Backscatterer in the first instance. I've no idea how we ended up there.

For 107 USD, which seems a bit excessive.

It is written that it will expire at13.12.2017 01:51 CET. Instead of putting receivers to BCC. Send only one person at a time at to section. And instead of using info at sender section use name.surname style. So systems automatically blocking emails and informs blacklists if they do not meet a specific rule set.

Thanks, we often need to send out an email to 20+ people, which would make sending one at a time quite a laborious process.

You can automate with programs/scripts like many headhunters. Search http://www.hotscripts.com/

Are you using your webhost as an email services or are you using a 'proper' email service. Pretty much a beginners error if you are using a shared webhost server for email - as that can't really be classed as a business level service.

 

[K0608]

Thanks, could you elaborate on your last post please? I'm afraid that I have no idea as to what 'automating with programs/scripts like many headhunters' means.

Thanks, I am using my webhost's email service. Would you recommend G Suite or similar?

 

[sipexa]

We are using G Suite as a base. And we are sending emails with in house made software. It connect to G Suite like outlook connection and sending email. But we are not flooding so many emails at a time. We are queuing them and sending with time delays.

 

[Alan]

^ G Suite is an example of a 'proper' business class email solution - they manage blacklisting - with G Suite there are limits, which are OK for small lists.

Would my IP Address (184.154.58.229) be the same despite having changed host?

No it won't be the same after changing hosting providers because you're (usually) sending email via the hosting provider's servers - 184.154.58.229 is used by SiteGround.

 

[K0608]

Sounds like business class email is the only solution.

 

[arnydnxluk]

Sounds like business class email is the only solution.

The issue should have been dealt with regardless, this really is just a case of your provider not doing their job properly. If you tell them the managed email service you have bought from them is not working properly - that you cannot deliver a recipient due to IP reputation issues - that's their issue to resolve. The response "it's nothing to worry about" is not sufficient.

A managed email provider (which includes hosting providers offering email as part of a web hosting service) should:

1. Do their best to ensure spam doesn't leave the network in the first place.
2. Take action to delist themselves where necessary.
3. Communicate with remote email server administrators where necessary.

How the service is marketed (personal vs business) shouldn't come into it - this is just a basic part of ensuring the service works as advertised. For example if I were to use Hushmail for personal email, I would not expect deliverability problems. A provider who doesn't deal with these issues appropriately simply should not be offering email services.

G-Suite certainly is a good email solution (and more). However there are also UK hosting providers out there who would value your business and take such issues seriously. I would also recommend FastMail for hosted email, although they're based in the Australia.

Hi Mike,
Thank you for your reply. As ever, it's useful and good to read. The general consensus seems to be ditch webhosted mail, and get 'business class' email. The trouble is, there's a number of providers and a variety of packages. We're trying to keep costs down, and whilst I understand that you get what you pay for, G Suite's entry level package only comes with 30gb or storage per user, unlike Office's Business Essentials, which offers 1tb per user. Fastmail also sounds great, but again, only 25gb storage and not much in the way of additional office software. All three packages are roughly the same price. Am I expecting too much for too little, or is Microsoft's offering the most cost effective solution?

 

[Alan]

Probably. But it is Microsoft. How much email storage do you need. I havent deleted an email in five years and only at 9gb

 

[K0608]

We're currently using Office 365 Home edition between three of us to store our work docs and files, as well as use their desktop apps, hence the appeal of the 1tb storage. I was wondering about using something like Libre Office which would negate the need to use Microsoft's desktop apps, and help keep costs down a bit.

Try using email spam checking tool like: http://emailcopychecker.com/

Also, depends on how clean your email list is, was it purchased or acquired?
