Forwarded emails from fasthosts being rejected

oz2net — Thu, 15 Jan 2026 12:28:23 GMT

My personal domain ( oz2net.co.uk) is hosted at fasthosts.

All emails sent to this domain are automatically forwarded by the fasthosts mail server (mailserver.livemail.co.uk) to my talk talk email account

Recently most of my legitimate emails forwarded via Fasthosts (mailserver.livemail.co.uk) to my TalkTalk address are being rejected.

Hi there @oz2net. I am sorry to hear you are experiencing issues, just to confirm do the emails go to spam or trash?

Hi - No they just disappear I do not receive them at all.

When I send an email to myself from another account this is the type of mail delivery failure report I receive.

Last reason: 421 4.2.1

Yes other people have been having emails sent rejected.

I know of at least 3 others

I have also sent test emails from 2 other email accounts I have (gmail & claranet) and they get rejected.

These rejections only show up after many hours.

If I send email directly to my talktalk account they are received straight away

I need to know what device are you using when accessing your email?

Re: Forwarded emails from fasthosts being rejected

I am using a Linux based laptop with Firefox browser accessing talktalk email through webmail.

I am also using a Windows 11 laptop with Chrome browser - No difference

I can also see my talktalk email on my android based phone through outlook and again no difference.

Philile-TT — Fri, 16 Jan 2026 12:35:52 GMT

Okay thank you. Are you having problems receiving emails from everyone, or just an individual or single domain name (e.g. @gmail.com)?

Re: Forwarded emails from fasthosts being rejected

The problem is related to emails forwarded from fasthosts mail server

To summarize previous posts :-

My personal domain ( oz2net.co.uk) is hosted at fasthosts.

All emails sent to this domain are automatically forwarded by the fasthosts mail server (mailserver.livemail.co.uk) to my talk talk email account

Recently most of my legitimate emails forwarded via Fasthosts (mailserver.livemail.co.uk) to my TalkTalk address are being rejected.

These missing emails do not end up in spam they just disapear

I have sent test emails from 2 other email accounts I have (gmail & claranet) and they get rejected.

These rejections only show up after many hours.

If I send email directly to my talktalk account they are received straight away

When I send an email to myself from another account this is the type of mail delivery failure report I receive.

I want you to speak to the email sender and confirm if they were able to sent the email successfully or are they seeing error message when sending it.
