I received this email from Reseller club

Hello,

Keeping up with our promise of providing you with the safest hosting environment, we have to make a few changes to our PHP installation on our Linux Hosting Servers. We will be disabling a few PHP functions that allow users to execute system commands on the servers that disclose system information in a shared hosting environment. These functions are sparingly required by clients and are more of a security threat to your websites.

The functions that will be deprecated are:

system, shell_exec, exec, passthru, php_uname, popen, posix_kill, posix_mkfifo, posix_setpgid, posix_setsid, posix_setuid, posix_setgid, posix_uname, proc_close, proc_nice, proc_open, proc_terminate

We will be making these changes on Friday, 27th of November, 2009. If you are using these functions in your PHP scripts, you will have to inform your customers accordingly about these changes.

Your co-operation is highly appreciated.

Regards,
Team ResellerClub

Question : Someone is sending spam and using my email address as the return path. I am getting 100′s of 550 error messages returned to my inbox. Any suggestions on how to correct this without deleting my email address?

Answer :

There is effectively nothing you can do about this, except to wait for it to stop.

Forging a return address on email is no more difficult than writing a letter, putting it in an envelope, putting someone else’s return address on the upper left corner, and dropping it in a mailbox.

If you’re using an email client program like Outlook to fetch your messages, you could set up a rule that looks for something in the subject line, for example, that identifies these bounce messages, and moves them all to a junk folder, for easier deletion.

Usually, the spammers don’t keep using the same address for too long – if they did, they’d start getting blocked. So, they switch spoof addresses pretty regularly, and your bulging mailbox should return to normal.

Also, check your website for any security holes, spammer may have used your scripts’ security bug to send spam.
