You obviously do not understand that any open port can be hacked.

Think about it for a moment an you will get it.

On a server which is managing say a few thousand dollars a day, only that, would you run multiple additional unnecessary services if you were competent?  I think not.

and by the way NO THEY ARE NOT MOSTLY MAIL RELATED SERVICES...

Now as far as exactly what each service is, I can detail them as well as you can.

Discovered open port 22/tcp on 111.90.150.219   Secure shell
Discovered open port 993/tcp on 111.90.150.219 IMAP over SSL (hope it was patched for HeartBleed)
Discovered open port 587/tcp on 111.90.150.219 Secure Mail (IMAP)
Discovered open port 110/tcp on 111.90.150.219 POP (mail)
Discovered open port 25/tcp on 111.90.150.219  SMTP (mail)
Discovered open port 80/tcp on 111.90.150.219  HTTP
Discovered open port 995/tcp on 111.90.150.219 MAIL
Discovered open port 143/tcp on 111.90.150.219 IMAP
Discovered open port 443/tcp on 111.90.150.219 HTTPS
Discovered open port 111/tcp on 111.90.150.219 RPC
Discovered open port 21/tcp on 111.90.150.219 FTP
Discovered open port 53/tcp on 111.90.150.219 DNS
Discovered open port 26/tcp on 111.90.150.219 RSFTP
Discovered open port 465/tcp on 111.90.150.219 SMTP SSL (hope it was patched for HeartBleed)

You completely miss the point.  The POINT IS many, many thousands of dollars per day are being handled by a server which has maybe 12 more ports open than it needs to do the SINGLE FUNCTION it should be doing.  That is only one of two things INCOMPETENCE or NEGLIGENCE.  That is it dude.  That is it.

You want email service, do it elsewhere.  You want SQL service, do it elsewhere.  Ok, so you want SQL service... FINE FILTER IT.  This server is offering services to the WORLD facing interface which it SHOULD NEVER OFFER.

I'm just saying.
