Hi @Elleni,
Even though I dislike answers which suggest to do do it all in a different way myself, can only agree with @filippo_carletti advise from own experience. Being a former small business owner went through the evolution of e-mail:
- from none in the mid 90’ ;
- to one “info” mailbox ;
- to a hosted pop3 account for every employee ;
- to a hosted imap account for every employee ;
- to the “get-mail” fetch pop3 solution ;
- to a full fetched mail-server (at the time M$ smallbusiness with exchange).
The main reason to invest in a ‘real server’ at that time was the cumbersome functioning and maintenance of the fetch pop3 e-mail setup.
There are compelling reasons to use NS as a frontend-mail-server such as a blocked port 25, high availability or a dynamic public IP address to name a few.
For me as home user it is the (theoretically) dynamic IP address. Theoretically because it has never changed, however the ISP has the right to do so. The solution I’m every happy with is the little known service batched smtp also referred to as queued smtp some hosting providers have.
