I have a couple of domains for all kinds of different projects, some on shared hosting (with a mailbox solution from the provider) and some on a private VPS.
My goal is to move everything to my VPS but the problem I currently have is that I don't know how to setup a mail server solution. Any advice would help me a lot, do you have your own mail server solution or are you using a 3rd party service?
Maybe some requirements that I currently have:
- Supports multiple domains
- SMTP so I can send mails from my backend application
- Can create multiple mailboxes if needed
I understand that there is not 1 perfect solution but any tips are welcome to help me reach my goal.
