For the record: zm.org does not send spam.
If you receive spam saying it's from zm.org,
it was not sent from here.
Spammers don't tell you their real email addresses.
If they did, the authorities could easily catch them.
Since spammers are criminals, they don't want to be caught.
They fake their email return address, either making one up
or listing a real email address they don't own.
It's like writing a fake return address on a letter
sent by postal mail: Anyone can write any address,
whether or not it's really theirs. In the case of spammers
pretending to send from other people's email addresses,
that's fraud, but (at least for now) there's no way to
always prevent it.
Sometimes spammers pretend to use zm.org addresses.
Again: Those messages do not come from zm.org.
We look forward to the day when spam doesn't work anymore
and there are no more spammers. Until then, we're as
inconvenienced by spam as you are.
