Most likely the server ip is in a blacklist somewhere that is causing the mail to get dropped into spam.
Thank you Skaero, no it is a dedicated static IP address specific on a commercial level and no blacklist database is not listed at all. I tried all from MXToolbox, Whatismyipaddress but all clean. Even if I run an email diagnostic to mail-tester.com and comers back everything is all good 9/10. Tells me I am not blacklisted, SPF record is valid, SpamAssassin is good, no broken links nor spammy html headers, fully authenticated through sender ID and SPF, successfully associated with my domain, my domain is assigned to a mail server all good. Bloody Microsoft servers and AOL, what the hell is hell on. My dedicated SMTP postfix server does not have issues and all emails route properly into AOL and Hotmail. The postfix or something must be injecting something for AOL and Hotmail not to like incoming emails but if I can change the outgoing mail that will be good.
