‘Mail delivery failure’ emails likely a scam
I’m having email problems. Several times a day I get “mail delivery failure” notices for emails I never sent. I also get emails in foreign languages that I can’t read. Some of these emails don’t contain any message, or the attachments don’t make any sense.
Is someone using my email address to send messages to other people? What should I do?
It’s possible someone has gained access to your email account and is sending messages in your name. But it’s more likely these are bogus emails from disreputable sources. Even the “mail delivery failure” emails are probably fake.
There are three things you should do immediately: Change your email password to lock out anyone who might be using the account. Stop opening suspicious emails and attachments. Run the free version of the Malwarebytes program in case the emails have installed any malicious software on your computer.
If anyone is using your email account, the goal would be to send junk or malicious emails to others using your name. The best defense against that is to create a strong new email password that would be hard for anyone else to guess.
It’s common for unscrupulous people to send fake emails designed to attract attention. The senders hope curiosity will prompt you to open an email or attachment, or to respond because you think it was sent by mistake.
If an email seems fake, don’t open it. Either delete it or send it to your email provider’s “spam” or “junk” folder (that may help the provider block similar messages in the future).
