Any ideas please?
I certainly have some ideas but it would help if you could clarify a few things that would troubleshoot exactly what is stopping you sending from these Ntlworld email accounts:
1) When you say "All other accounts are OK." are these other email account also from Virgin Media domains (such as Virginmedia.com or Blueyonder.co..uk) or are they non VM addresses such as Gmail.com, Outlook.com?
2) When you say "can receive, but not able to send" is that when you are using an email client or app (such as Microsoft Mail or the Apple Mail app) to manage your Ntlworld emails or are you managing your emails using Virgin Mediia's Webmail service on the VM website?
3) If you are seeing this problem when using an email app / client, I would try signing into your VM webmail account for these Ntlworld addresses and seeing if you can send emails successfully from there. If you open the link @Robert_P has already given in their post "We have help here for webmail" it gives you the link to "Sign in to your mail account. You can use that link to access each of your Ntlworld accounts an try sending a test email.
For what it's worth, my initial idea is that if:
- you are able to successfully send emails from other email providers (see point 1)
- you cannot send Ntlworld emails using an email app or client (see point 2)
- but you can send Ntlworld emails when using VM's own webmail service (see point 3)
that all suggests a situation that many people have reported over the years where VM are blocking VM emails coming from your home network IP address because it is on a blocklist (formerly known as blacklists). That is probably because there is evidence that a device on your home network has been infected with malware.
It would be great if you could post back to confirm that my three bulleted statements are all correct and reflect the situation you are seeing. Armed with that information, forum members can then offer you some constructive advice on how to move forward with this.
On the other hand if those three statements don't reflect what you are seeing then my initial idea is likely to be unfounded. However at least that new information will be helpful to determine the real reason you cannot send VM emails.
I hope that all makes (at least some!) sense.
