In the past few days I have been receiving a lot of "Mail delivery failed: returning message to sender" emails.

How can I tell if I am infected and sending out spam??

Hi spmccord,

Just wanted to give you an update. We've changed your email account password to stop the spam coming from your account. We've done this to be pro-active to keep our systems administrators from temporarily suspending your account.

Hi spmccord,

Thanks for posting your question. I'm more than happy to assist you. I've looked over your account and there's a lot of unusual activity from the steve@ email account.

From looking at the mail logs, it appears your email account has been compromised. We suggest you change your email password immediately. Please be sure to use a strong password that contains letters, numbers, and symbols. Also passwords are case sensitive so use a combination of upper and lower case.

Now, you'll also want to run a malware scan on your local computer to determine if there's a virus that may be harvesting your email password. We've seen a number of these occurances with Mac users in recent days.

Be sure to check that all the software on your computer is up to date as well. Software updates often contain patches for security holes so it's of the utmost importance to make sure all your software is current.

If you need further assistance please feel free to contact us.
