For months I have a problem with my outgoing mail server, frequently reaches its destination to the spam folder, usually when sent to domains like gmail and hotmail (most important for me)

I have a VPS administered under Parallels Plesk, I have not misconfigured anything, everything is default and I understand that it creates PLESK DNS templates are appropriate. Reverse DNS is working, I can not think of anything else, if anyone can help, please appreciate it.

You have multiple domains on my VPS, one of them, the principal, is: Moved Permanently

Thanks a lot.
