TalkTalk.net domain SMTP mail server not responsive

KeithFrench — Thu, 17 Jul 2025 14:36:57 GMT

The TT SMTP Outgoing mail server looks like it is down. I am trying to send emails & the SMTP server times out:-

SMTP Mail Server down

Please, can you get this mail server checked out.

Hey there, @KeithFrench. We will have to have more examples of customers experiencing this so that we can let Lorraine submit an incident.

Not sure @kanya-TT, I know of at least one other TT customer in a totally different part of the UK that is affected. It could be the start of a bigger outage.

Hi @kanya-TT

I have just tested webmail & that is fine, it is only SMTP that is affected.

I will have to escalate this with Nic and gather more examples. Kanya

ferguson — Thu, 17 Jul 2025 15:17:14 GMT

But I have literally just tested again and it seems to be working now?

How about you @KeithFrench?

Hi @kanya-TT

Like @ferguson I have just retested it & it does seem to be OK. I wonder what caused it?

I am not sure @KeithFrench, we are of late having challenges with our emails, but we will need to further escalate this.

Hi @kanya-TT

Just tried it again & it is still not working. Additionally, there are a significant number of people complaining about the same issue now. I have listed a few of them below. Could you please raise an incident?

Hi @kanya-TT

It is definitely still down.

Re: TalkTalk.net domain SMTP mail server not responsive

kanya-TT — Fri, 18 Jul 2025 12:30:14 GMT

Noted @KeithFrench. We will have to wait for response. Kanya

Hi @kanya-TT

It is very intermittent. It is still down at the moment.

Hi @kanya-TT

I have been doing more work on this and I am not convinced this is actually a TalkTalk issue. It looks like something has caused the SMTP mail server (outgoing emails) password to be erased in the email client. Putting it back seems to have resolved the issue. Thunderbird is easy, New Outlook for Windows can be more involved.

Thunderbird

When requested, enter the correct password in the screen below & normally tick the "Use Password Manager to remember this password" option. Then click the OK button:-

SMTP password

New Outlook for Windows

This can be more complex, as it may result in a "Username is not recognised" error.

Resolution

Assuming that the username is correct, click the X at the top right of this window:-

Incorrect username

First, try clicking the Troubleshooting button below:-

Troiubleshoot or Advanced setup

If that does not fix the issue, click Advanced Setup above.

Note: this will remove all email accounts from Outlook. So long as the emails etc are held on an IMAP server, they will not be lost. I cannot be held responsible if you lose any data.

Double click IMAP below:-

Select IMAP

It will be seen that the password has been cleared below; replace it with the correct password. In addition, when scrolling down this page, check all other configurations, particularly the SMTP password:-

Enter password

Once done, click Continue. Then add back in all other email accounts & check the configuration.

If this still does not work, I will try to help you individually. In that case, please PM me (to preserve your privacy) a screenshot of your complete IMAP/SMTP configuration, so that I can check it for you.
