Forwarded emails from fasthosts being rejected

[oz2net]

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.

[oz2net]

No Fasthost is where my personal domain is registered.

Emails sent to that domain are then automatically forwarded by the fasthosts mailserver to my talktalk email account.

I view these emails and send emails through talktalk webmail.

@oz2net just to confirm fasthost is a mail client that you use to access your TalkTalk emails? 

[oz2net]

I have sent emails from 2 other email accounts I have one with Claranet and one with Gmail. Therefore I am the sender

If they are not correctly forwarded to my talktalk email it will generally be many hours (up to 24) before I receive an error message.

I spoke to one other sender and it was exactly the same 20+hours

Other missing emails are automated emails from people like prudential, dropbox, ticketmaster etc and therefore not possible to speak to sender 

As per shown in example in previous post the error message is always   421 4.2.1   Connection deferred

[Philile-TT]

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.

[oz2net]

yes   -   which is most of the emails I receive

[Philile-TT]

@oz2net to answer the questions it only emails forwarded from fasthosts? 

[oz2net]

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.

Last reason: 421 4.2.1

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

[oz2net]

yes no problem

[Philile-TT]

Are you able to send emails? 

[Philile-TT]

Thank you. 

[oz2net]

yes

[Philile-TT]

I just need to confirm is it the same email address you confirmed privately? I need the first part however please do not confirm it here publicly. 

[oz2net]

talktalk.net

[Philile-TT]

Could you please tell me the last part of your email address? This is the section after the @ symbol.

[Philile-TT]

Thank you for confirming that. Checks are currently underway.

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.

[nambuso-TT]

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

[oz2net]

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
