Consequently, I don’t know just as much as I should about adventures with email.
I designed/coded/manage the website for the small company I generate. Recently, we been given around 70 " made a comeback to sender" postings… considering that all of us don’t send more than 5 to 6 emails a day time I found this particular rather odd.
After i had a run through them, it appears our domain email has become somehow hijacked in order to send penis-enlargement unsolicited mail!! From email balances with our website name that don’t really exist.
Consequently, is there any way I can figure out just what happened, how I can fix it, and how I can prevent it coming from happening again Personally i think it’s my responsibility since I am the one who manages the web-geekery at the job.
If this isn’t the place to ask, can someone you need to point me while in the right direction Thankyou a lot.
There’s nothing can be done to stop this, basically because the odds are that the e-mails didn’t originate from a server at almost all… e-mail is an exceptionally insecure medium… with a several lines of php you could write a system to loop through a listing of e-mail addresses and send everybody a mail having any " from" address you wanted… I’m guessing that is pretty much exactly what happened here…
What you should do, however, is make certain that your SMTP machine is nailed along… make sure who’s requires authentication to ensure folks outside your own organisation can’t utilize your server that will relay messages, as which could lead to ones IP address staying blacklisted… also when you’ve got any formmail scripts in your sites make convinced they’re locked along too, so that people can’t use them as an easy way to relay… ensure they check this domain calling these individuals…
