I am reciving this strange mails in my mailbox as if I am sending some mails to other pessons BUT I AM NOT. What is going on? How can somebody send mails from my account?

Here is one tipical:

Your message to: was blocked by our Spam Firewall. The email you sent with the following subject has NOT BEEN DELIVERED:

Subject: I know, it's a bit of a thin rationalization, but I own the little beastie now, and that's my story.

Here are details:

And headers text:

Can please somebody from PHP Fusion gurus explain to me WTF is going on with this emails please. Does anybody else recives so many of this postmaster emails like this:

The original message was received at Wed, 21 Mar 2007 11:47:34 -0400 from []

----- The following addresses had permanent fatal errors ----- <>
(reason: 550 5.1.1 unknown or illegal alias: )

----- Transcript of session follows ----- ... while talking to
>>> DATA
<<< 550 5.1.1 unknown or illegal alias: 550 5.1.1 <>... User unknown <<< 503 Need RCPT (recipient)

It looks like php fusion is been used to send unsolicited emails to other people. How can that be?

its not that hard to forge the headers of an email message so that they appear to be sent by you, and i supose thats the case.

i'd suggest adding a spf (sender policy framwork) record to your domain's dns settings indicating the servers that are allowed to send email FROM your domain:

Many spam checking engines use SPF to determine if an email is actually comming from where it claims.

Read up on SPF here:
