Are You Receiving Email Bounce Messages For Emails You Did Not Send?
Lately there has been a rash of malware installing itself on computers and stealing email login credentials resulting in mass emails going out using the unsuspecting victim’s email account.
What they do is, crab your email credentials, set up an email account using those credentials and send hundreds of thousands of emails from your mail server.
This means the server IP addresses get blacklisted as spamming machines by other providers, hence blacklisting everyone else using that server. If you are on a shared hosting server cluster, other companies and individuals that are also on the same cluster would be affected too.
It may not be your fault because these idiots are out there but from the server admin’s point of view, the onus is on you to protect your machines and scan them regularly for malware, spyware and viruses.
What we MUST do!!!
The most obvious clue that you have been attacked would be if you start receiving several email bounce notifications for emails that you did not send. This should tip you off that someone is using your credentials but instead of sending the bounce email notifications to your trash and ignoring them or setting a spam rule to filter them out so you no longer see them, YOU MUST TAKE STEPS TO FIX THE PROBLEM.
The server admins are spending a ton of time tracking down offending email addresses and tracking down providers to have the server cluster IP addresses removed from blacklists.
If you do receive several email bounce notifications, the solution is simple, change your email password on the server and scan your machine before you change your email password on your machine. VERY SIMPLE BUT YOU MUST REPORT IT TO YOUR SERVER ADMIN IMMEDIATELY OR FIX THE PROBLEM YOURSELF.
This could happen to you no matter where your domain is hosted. If your computer or network is infected and you ignore it, you could spread it to others on your network and potentially to the email contacts on your machine and to the contact lists on the other machines in the network loop.
PLEASE PROTECT YOURSELF, YOUR NETWORK AND YOUR CONTACTS. SCAN YOUR MACHINE REGULARLY, CLEAN OUT YOUR TEMPORARY FILES AND CACHE BEFORE YOU SCAN. I CAN TELL YOU HOW TO DO THIS AND SEND YOU THE TOOLS TO DO IT.
