Help: E-mails being sent as SPAM

[Mysterio]

Hello guys,

I have a problem on my server (dedicated server): every email I sent through main or other addon domains, is being recognized as SPAM email from GMail, Hotmail, and Yahoo also (I tried those three).
My question is: what may cause it, and how to solve it?

I am sure most of you work on servers and many of you may faced this problem.

Any help is appreciated!
Thank you!

Seems your ip has been blacklisted, you can check here Email Blacklist Check - See if your server is blacklisted
and if its seems blacklist then you can use this service http://sendgrid.tellapal.com

As it seems, it was blacklisted!
Switched to another server actually (hostgator - their support is good).
