I was wondering if it is possible to build your own SMTP-server and if it is, then i would like to know how. I have 2 older pcs which i can use to do it.
I wanna give this a go since i have a mail-account where i can receive mails but can't send them unless its done directly online.
It would be nice if someone could tell me what i need and where i can learn it.
I prefer using ubuntu server so thats why i came here.
