[CentOS] Which is better? Microsoft Exchange 2016 or Linux-based SMTP Servers?

[Turritopsis Dohrnii Teo En Ming]

Dear Jonathan Billings,


Admittedly, I am a bit confused.


Thank you for enlightening me with more in-depth information.

I think you're a bit confused about what an SMTP server is.  Exchange
typically provides several services, one of which is SMTP.  Comparing
features of Exchange to similar products in the open source world is
going to be difficult, because Microsoft has a vendor lock-in that
makes it difficult to exactly duplicate every feature.

On Linux, an SMTP server can deliver locally to a file (such as
/var/spool/mail/username) and you can read that file with several
MUAs, but it sounds to me like you're asking if there is a way to have
multiple folders.  That's more like something provided by an IMAP
server.  Typically mail arrives in your mailbox via SMTP, and is then
delivered into a mailbox that is read by a completely separate service
that provides the IMAP protocol (or POP3, but I hope not).  IMAP
servers can provide you with many different 'folders' and not just an
INBOX.

There are several IMAP servers for CentOS, for ease of setup I suggest
dovecot.  If you need a webmail client for your mail service, I
suggest RoundCube (package name: roundcubemail).  I prefer postfix for
SMTP although there's also sendmail and exim.
