I have a dedicated server hosting 2/3 web apps (web-server + SQL server among other things) on Debian.
Now from time to time theses web apps send mails to their respective users using SMTP services like SendGrid.
I'm planning on rebuilding a new server config.
The only thing about email I want this server to do is: letting web apps send email through external SMTPs.
I don't want the server from acting as SMTP server, nor POP or IMAP. To be clear, if I could completely drop email support from the software stack of this server, that would be awesome.
- Is this possible?
- What is mandatory?
- What is irrelevant for my use case?
