Message Delivery Failure - Anyone else having problems?

[jingars]

The latest mail delivery failure message I have received is dated yesterday at 19:08, but it refers to a mail sent in the hours prior to @RobbieMac's update re a fix being implemented. I have yet to receive an error message for an email initially sent "post-fix", but as we don't know about what we haven't received, difficult to confirm the state of affairs; Roger's update does sow a seed of doubt...

Hi Everyone,

We've had a further update from our email experts and they've noticed that some of you don't have an SPF record added to your domain name. This can cause issues as anti-spam filters may not treat the email as coming from a trusted source. 

There is guidance on the 123-reg support site that explains how you can set this up. I hope that helps?

Thanks

Neil

Hello @NeilO, thanks for the update and will review the SPF links provided - very good of you.

The link you have provided asks; "IP addresses in CIDR format that deliver or relay mail for this domain", "Add any other server hostname that may deliver or relay mail for this domain", and "Any domains that may deliver or relay mail for this domain"

This is whole new world to me; can  you advise what the above entries in the SPF record should be to cover the outbound BT email servers? I don't want to break the facility to send email whilst trying to fix the receipt of it 😉

Thanks for the update.

I've just received a new delivery failure, this one dated Thursday 8:35, so after the fix it would seem.

Thanks for the SPF pointer. I've added the 123-reg mailex.mailcore.me SPF to my domain and will see what happens in the next 24/48 hrs

thanks

All the delivery failure notifications that I have received have been after a delay of around 24 hours.  I don't know how many attempts are made at delivery and it's not so easy to detect emails that have merely been delayed.  What has become clear now is that I have lost some important emails completely, perhaps because the notification wasn't delivered.

The majority of the emails I receive are notifications from my CCTV cameras.  Interestingly, I haven't received failure notifications for any of these.

I'm also annoyed that it doesn't seem possible to disable the Junk filter.  What I have considered for years to be a solid email service is now becoming less so. Disappointed.

Have you tried the 123 email settings as suggested in message 32?

Hi @jingars I'm sorry that's not something I can offer you support with. If you need help setting up the SPF record you'll need to get assistance from your domain provider 123-reg, sorry.

@NeilO, The 123 Reg link details the settings required if you are using 123 Reg for email. 

I am not using 123 Reg for email; I am using BT. I don't think it is unreasonable to ask BT the IP range and domains of their outbound BT email servers in order to comply with a fix that BT has pointed their users towards.

Step 1: Gather IP addresses that are used to send email (for me, that's BT)

@jingarsthe 123-reg guide says:-

Please note: If you are using 123 email, then you should use the following SPF record:

v=spf1 mx a ip4:94.136.40.163 a:mailex.mailcore.me -all

It is 123-reg's mail servers doing the forwarding, and all of the delivery reports are coming from mailex.mailcore.me, Which is 123-reg's So i've taken that as affrimitive that i'm using 123 email. I've put their SPF in my domain and will see what happens.

@sbadger I think our posts crossed; as above I am of the view that SPF record needs to  include the BT mail servers as I send email via BT, not 123 Reg.

For me, 123 Reg acts only as a domain registrar and DNS provider.
