I am having trouble with an ntlworld.com account. I can log into webmail and can send and receive but can't connect from Outlook, iphone mail or any other remote devices.
This started happening a few weeks ago. Initially, the device stopped sending email over smtp.virginmedia.com but we could still receive email. Since then we have changed the email password and can still log into the VM portal and email ok. However, now we can't logon for IMAP or SMTP at all on any devices.
Test shows
< 525 5.7.13 Authentication Denied (VM321)
* Closing connection 0
* schannel: shutting down SSL/TLS connection with smtp.virginmedia.com port 465
curl: (67) Login denied
This to me would indicate an issue with the username and password but they seem fine.
We have also looked at Spanhaus and we are not on the list for the IP we are using.
If we switch to login in from our Virgin media internet connection I get
< 235 2.7.0 SMTP350 Authentication successful for user XXXXXXXXX@ntlworld.com ;id=7wP5q7ecZq3uK;sid=7wP5q7ecZq3uK;mta=csmtp6.tb.ukmail.iss.as9143.net;d=20230610;t=130507[CET];ipsrc=[MOD EDIT: Personal info]

Why is Virgin email only authenticating correctly over the Virgin network? We need email to work over mobile and wifi.

@cmarston1500 VM have recently changed the log in requirements for accessing VM Mail via third party apps.
If you change the password for the account in My Virgin Media > Account settings > Account details you will not be able to use the new password to access the account via an email client. Email client access now requires an app specific password which can be generated in the MyVM > Account Settings > Account details > Mailbox App password management
Once generated use the app password in place of the VM webmail password when using an email client.

The error code indicates there have been too many unsuccessful authentication attempts within the last hour resulting in further attempts from same network / IP Address failing. To resolve the issue:
NB Virgin Media recently introduced an App Password that should be generated and used when configuring email client. To do this sign in here My Virgin Media | Virgin Media, select Account settings > Virgin Media Mail settings > Generate new App password and update all email clients with new app password. Already mentioned by Graham_A in previous post.

I had the same issue with the iphone when I tried on the Virgin network IP address. This is a circuit I manually switch over to so nothing else would be trying to access the account.

Perfect that is great and now we have a thread for this that should assist others as well.

Note the App password worked for imap, but SMTP is still rejected. SMTP was the original problem we were trying to fix so I am actually no further forward.
SMTP send using the App generated password

As another test. If I connect my internet connection back to using Virgin SMTP works with the generated App password
curl -v smtps://smtp.virginmedia.com -u {username}@ntlworld.com:{apppassword}
* Trying 212.54.56.51:465...
* Connected to smtp.virginmedia.com (212.54.56.51) port 465 (#0)

If I switch back to a non Virgin internet connection we are back to SMTP authentication failure.

@cmarston1500, as a matter of urgency generate a new App Password as the current one was disclosed in the earlier posted curl outputs; forum moderators have redacted it from posts.

Check if the non-Virgin Media network connection's IP Address is listed by Spamhaus. To do this:

Ok will do. The IP for the other network is not on Spamhaus. I have tried from different VPN IP addresses and mobile sim data.

Virgin Media have their own block list on which the public IP Address appears. I can only suggest than when the issue next occurs run the curl command and post just the VM error code here or error messages shown.
