My servers default email address sends spams to people. I have a very very strong password. Can somebody help me out about what can i do? I am about to be suspended from my hosting company because of this.
Hi, you may be the victim of email header injection. Check and filter email, messages etc very strictly for user input. Don't allow words like Bcc: Cc: etc, google "email header injection exploit" for more info.
This is what my hosting company said after i mentioned them about the email header exploit "Ed: [5:08:05 AM] Yes, but that is not the case at all. reason we know is because the server tracts emails coming to and fro the server, header exploit will have the same message and affect multiple accounts on the server. As well as cause other issues. [5:08:52 AM] Your account is sending messages to random emails, I just found some: , , , " These all seem to be uk email accounts. Definitely spamming.
similar happened to me many years ago while hosted the cause was: my site was hacked and contained a phising site setup for sending mail and other bad stuff check your entire webspace for files NOT belonging to you my host then gave no clues, just that I was sending too many emails
Check your server security and your script: +) Your SMTP account +) email header injection +) Auto send email script
Check if your script is updated or not. best bet is to take a DB backup of your forum. completely delete all files and folder from your hosting account. delete db , db username. now install freshly the forum script and upload the db again and connect. make you if you have any theme customized , take backup of that as well.
