I've looked through all the associated posts but these does not solve my recent problem, which came about when I reset my password.
Through my client email apps, I can happily receive IMAP emails but cannot send.
VM help desk reset my password (to a very basic type) and it worked. When I came to reset the password to something harder - but within the stated constraints, it failed again. They then put me through to their paid service line who argued that since VM webmail works for me, then it must the fault of my email client.
I informed that both android and Mac mail clients could not send email via the VM SMTP server smtp.virginmedia.com, port 465 , SSL. They would not listen.
That error message is triggered when one or more of your devices attempts to authorise on the SMTP server with an incorrect password. Too many failed attempts in an hour lead to access being locked. Access is restored after a time.
So, you need to work out which device is still using the old password and update it.

I think you have a infected device. Checking the log data (for your Forum-registered email) for the 1st of January I note numerous authentication attempts, approx 2 every minute from 21:58:46 up to 23:59:04. These all indicate invalid credentials. As they originate from your WAN IP I don't think your account is compromised as such.
Please go through the settings of all apps/clients and ensure the username and password is correct.
If that doesn't help, post on here and I'll message you for more details for further investigation.
On all devices in your house - including family members who also use Virgin Media email addresses
Check the Outbox on each device for an unsent mail. On each device with a mail in the Outbox go into the account settings. Delete the password on the Outgoing server Re-enter the password on the outgoing server.
If you need help with a specific device tell us the model and we'll try and give device specific instructions.
P.S. I've never worked for CapGemini.
