I am trying to use the console in Fedora 17 to send an automated email to myself.

I run this:

echo "email content" | mail -s "blah" [email protected]

It works fine, google treats it as a spam email, but when you mark it not spam everything is cool. For Hotmail there are policies to prevent the email from being sent.

I do this:

echo "email content" | mail -s "blah" [email protected]

And the email returns as undeliverable, the email does not even appear in the spam folder and I get this as a response:

... while talking to mx3.hotmail.com.:

So apparently hotmail doesn't like spammers so much, they they are blocking anything with a dynamically assigned IP range. Google does not do this. What is the easiest way to just get around this and send an email to hotmail and end up in their spam folder to be unblocked later by the user?
