Based on some googling it seems that a 3rd party SMTP would already have a good sending sore were as a self hosted email server will take some time to build a good sending score (which I'm ok with)
I want use my existing VPS to send mail but after asking my webhost about it they said its better to set up a 2nd server just for mailing, something about IP address, DDoS attack etc... I'm not very technical so I wanted to see if this is true
Is there really a difference in a.) Web server + Mail server VS b.) both web and mail on same server? or are they just trying to sell me a 2nd VPS
What do you think?
