I have just setup a VPS with CentOS and Webmin. I am attempting to setup my email server. I can successfully send mail, however it always gets blocked by spam filters. What steps are needed to make sure it does not get blocked?
Domain: HostAxel.com or MafiaStreetWars.com OS: CentOS Setup method: VirtualMin & Webmin Server Type: Postfix
On a seprate note.. I cannot receive email either. I don't know if this is a related issue or not.
I got this as a reply from a hotmail address:
