Someone using my email account address, How can I stop someone else from using my email how to fix this issues
I was shocked when I got over a dozen text messages from my friends and colleagues informing me that pornographic content was sent to them from my email id. I was shocked and petrified and immediately called my friend who is an IT expert and asked him how can I stop someone else from using my email.
I was so naïve and never and did understand the importance of maintaining the integrity of my email account and learnt my lesson the hard way. None the less, I was so surprised to know how simple it was to change my password and security settings and prevent someone using my email account address.
Like me, you can just follow these simple steps and stop someone using my email account address.Just log into your email account and access the settings options. Here you need to do two things. One, click on device activity and security events options and check on which devices has your email being accessed recently. In case you find any device which is suspicious, you can remove them from your access list, and this prevents any attempt of logging into your account from the restricted device.
Also, when I have the slightest doubt that someone using my email account address, I change my email password using these simple steps. Sign into your Gmail account, click on sign-in and security and change password.
Linking my mobile number and an alternative email address was the answer to how can I stop someone else from using my email? In case your email account has been hacked and is being misused, the OTP on your mobile phone, and alternate email address can help retrieve your email account.
Never sharing email passwords, always logging-off my email account when using a public computer and continually changing my passwords is how I prevented someone using my email account address.
How To Prevent Someone Else From Using My Email Address (Spoofing)?
With the way that SMTP works, anyone anywhere can specify any email address as their From address as long as they have a mail server that allows them to do so. From address may be completely false or even non-existent.
Note: There is no way to prevent other people from using your email address. There are no services that can completely prevent spammers from using your email address since they are using a different mail server. Inter media has no control over it. However, you may want to protect your account using the following methods:
Typical spoofing situations
In general, there are two situations that can make you aware that your email address was spoofed:
You receive bounce back emails or replies to messages you didn’t send:
There is no way to prevent the bounce back messages from coming to you. If a message gets returned to the sender, it goes to the actual holder of the From address, regardless of who sent it. Similarly, when someone replies to a message, it always goes to the reply-to address.
You receive messages with your email address in the From field (or in both To and From fields):
Make sure that your domain and/or email address is not whitelisted either in Outlook/OWA.
Remove your domain from:
Email Security Safe Senders List.
Email Protection Safe Senders List.
Personal Safe Senders List
In such situation, it is recommended to create an SPF record for your domain. SPF helps mail servers to distinguish forgeries from real mail by making it possible for a domain owner to specify the IP addresses/servers from which mail can be sent. That way, if any other machines try to send mail from that domain, the recipient mail server knows that the From address is forged.
Failed SPF validation will add supplementary spam score to the spoofed email and this will increase the chances that this email will be delivered to Junk.
Note: SPF is designed to check the domain listed in the Envelope-from address, rather than the From address. Spoofers will exploit this by using a domain without SPF records as the Envelope-from and using the recipient domain in the From address.
Blocking spoofed emails
Email Protection Lite
Email Protection and Email Protection + DLP
With Email Security, you have the following options to block messages with a forged From address which might be, in fact, your own email address or some inexistent email address at your domain.
If you have only Exchange mailboxes on the account you may want to add your own domain to Blocked Senders list. This action won’t affect internal mail flow since mail delivery between internal users isn’t filtered.
If you have Exchange mailboxes and also have SMTP-applications (e.g. printer, web form, etc.) sending mail to the users on the account, you still can add your own domain to Blocked Senders list, but make sure you added From email address or IP address of the application to Safe Senders.
If a part of the users on the account has POP/IMAP mailboxes, blocking your own domain won’t be the best option, because you will need to add all existent mailboxes to Safe senders list. This technique has its drawback: spoofed emails which appear as coming from the existed email address on the account won’t be blocked as such email addresses will be added to Safe Senders list. So this option is useful only if you receive spoofing from an inexistent email address at your domain.
Email Protection Lite
With Email Protection, you have the following options to stop the Header from spoofing:
If you have only Exchange mailboxes on the account, add your own domain to the Blocked Senders list.
Add any external senders that should legitimately be able to send as the domain to the Safe Senders lists. This will override the domain-wise Blocked Senders list. If the external senders are SMTP-applications (e.g. printer, web form, etc.) it is advised to add the sending IP address to the Safe Senders list.
