We have cleaned up server NC027 after a client’s email account was compromised, resulting in thousands of spams being sent from the mail server. This is having a negative impact on email being sent from the server, as its IP address is now in anti-spam blacklists. This means that outgoing email sent from our clients will be bounced or delayed until the blacklist realise that the spam from our mail server has stopped.
We are working on implementing a workaround through one of our other, clean mail servers, but unfortunately it will be several hours before outgoing email to most domains is delivered normally.
These incidents usually arise after a computer has been infected with a virus. The virus then sends the email password back to the person or organisation controlling the virus, and they then use that information to compromise that email account on the mail server, using it to send thousands of spams from the account. Please ensure that you install, use and update an anti-virus program on your computer to ensure that this doesn’t happen to your email account.
We apologise for this incident. Please contact us if you have any questions. Thank-you.
