Anyone can email from my website domain!?

Please help me to make them understand what they have done (or undone) to cause this!

how do you know anybody can send through your domain.

Anybody that sends an email can make it look like it came from wherevever they want.

Spammers use this alot, I even get mail that looks like its come from me. All the spammers do is change the from details in thier email options. The chances are they are not actually sending it from your domain

Anyone can email from my website domain!?

Sending emails is not restricted to your ISP, if I know your domain, I too can set my Outlook to say it is sending from your domain while I am really sending from my own SMTP server via my own ISP services.

Are you sure the email is going out from your own website? Do you have a Webmail service on your site ? Have you tried login in to it yourself with a wrong user name and password ? If you can, simply document your steps in an email and mail it to your support explaining your problem and how to replicate it,

If you can not replicate the problem, I would think it is spammers who has recorded your email address and are flooding others under your name. I get that done to me as well. I simply ask the people to look at the Email headers to see where it really came from (SMTP server).

Hope this helps

Other Replys:The ability to send email (SMTP) via your domain WITHOUT user/password protection depends on several things.

SMTP servers usually allow email to be forwarded if it originated on the same network and contains a correct from address.

The only reason you would need a username and password is if they have setup secure SMTP. They may do this if they are allowing SMTP forwarding from outside their network.

Is you domain hosted with your ISP ?

if it is then when you connect to your ISP you are given an IP address which puts you on their network. The SMTP server will then allow you to forward (send) email without a username and password.

This does not mean anyone can send email via your domain. The way to check for an %26quot;open proxy/smtp%26quot; is to use one of the online port/proxy checkers. Put in the smtp.domain.co.uk address of your smtp server and it will tell you if it is open or not. If it is OPEN then you need to contact your hosting company and tell them to fix it.

If your domain is hosted on your own server (rented), virtual server or even your own computer, then YOU need to plug the hole.
