unauthorized email being sent from my account?

by mkaresh / January 26, 2007 4:28 AM PST

I received this email in my yahoo account (from "Mail Delivery System").

This message was created automatically by mail delivery software.

I never created an email like this. What does this mean? How or why would email be generated from my yahoo account & going to some other country? (that's not my actual addy above- I overtyped, btw) This is the second notice like this that I have received this week.

If I should look somewhere else for help on this, please let me know.
Thanks!

Usually there are several in a cluster. I do not send anything like this and it does not appear in my Sent folder.

spam
by Jiri_AVG AVG Staff / November 19, 2009 6:22 PM PST

a little bit of a technical explanation:

If this has not been sent from your account (just to be sure, you can change your Yahoo mail password), this might be caused by some spammer, who knows your e-mail address and puts it in the "Reply-To" field of the e-mail header. Then, tries to send to various addresses using bots and rogue/flawed SMTP servers and if those SMTP servers don't know the address, they simply get the response "we don't know this address" back to your e-mail account.

Not much to do to avoid this, but removing such messages if you haven't send them.

I have the same thing going on, help!

In reply to: spam

I am assuming they got my email from Craigslist because in the mass emails it has Craigslist somewhere in the subject or writing. I see that they are trying to send things to my contacts. Are my contacts getting any emails? And what would they be if they are?
