I am running a mail server and suddenly I am receiving emails that are showing up as undeliverable yet no one has sent those emails from our server. I paste the properties of what appear in emails as the source. Have I been hacked or what.

You haven't been hacked

by gene.fellner In reply to Email

Your e-mail address is posted in a thousand places. I'm no techie, but apparently it's pathetically easy for someone who knows what he's doing to send out an e-mail with your return address. Of course another techie can wade through the cryptic code attached to the e-mail and find the true sender's address. But you and I don't know how to do that BECAUSE WE SHOULDN'T HAVE TO. Any more than we should have to be know how to rebuild an internal combustion engine in order to minimize the chances of our cars being stolen.

There's an article right here in today's issue about the fact that most security breaches are due to the fact that software is not well built in the first place. E-mail software should utilize encryption to prevent both impersonation and interception. Too expensive? Too slow? Sorry, the technology should never have been made public in the first place without those features. If they had been part of the original requirements, a way would have been found to satisfy them.

I get them often

by JamesRL In reply to Email

I have used the same email address for 10 years.

I get tons of messages from undeliverable mail, because someone is using my address to spam others.

The real pain is that now some mail servers block me.

it's a spam message to begin with.
( your email provider is based in the us, so a real undeliverable from them would be utf-8 not utf-7 )

save entire message, including attachments to disk, then open each in notepad. ( any executable just delete, it will be a virus )

the full headers will have a originated field, which tells you who is sending the spam.
