SSL is primarily designed to encrypt the data 'on the wire'. Certs and cert 
authorities are designed to try bring some level of trust that you are talking 
to the server you intend to be talking to.

If your network is secure then there's likely little 'need', per se, for SSL - 
but anyone on the network can do a network packet capture and catch the mailbox 
user login and app logins - which is not a good idea.

If you're doing this for work and paying users: encrypt the data on the wire.

If you're just monkeying around at home: shave whatever corners you want, but 
learning SSL is important so take the time.

TL;DR: Use SSL.

Subject: LDAP and SSL

I'm struggling with the need for SSL...

We will use our new LDAP for apps. These servers are all locally housed so each 
app server will talk to the LDAP server over our network. (why) Would we need 
SSL?

What about for mail services? It seems to me that our mail server would also 
talk directly to the LDAP server...what am I missing here that dictates the use 
of SSL with LDAP? I could see if one had their LDAP open to be accessible 
direct access from off-network. Perhaps SSL is used simply as a means to 
authenitcate?
