"Super frustrated though that site ground won’t allow me to split my MX in the DNS files. I have a Google workspace account for my personal work email and I’m required to have all of my Website email accounts go through GOOGLE. I can’t split them up so that the admin@ or the no-reply@ for my website to go through site grounds SMTP super disappointing. But the customer service was great honestly it’s always great. Just wish they had this feature."

How Does SMTP Hosting Work?
The operation of SMTP hosting can be understood as a two-step process:- First, SMTP is used to send the email from the sender's email client to their email server.
- Next, the email gets relayed to the recipient's email server.
How to Host an SMTP Server?
Hosting your own SMTP server involves a series of steps:- First, you need a dedicated server or VPS to host your SMTP server.
- Next, you install an SMTP server software like Postfix or Sendmail on your server.
- Then, you configure the SMTP server according to your requirements, setting rules for outgoing mails, authentication methods, and more.
- Finally, you need to ensure your server is secure, as SMTP servers can be a target for spammers.
