Setting up mail on iphone

[NenadJovanovic]

My webmail Is working fine when sending and receiving emails, How would I setup the same thing on Iphone.

Here's what I'm trying:

Incoming Mail Server
Host name: Mail.Domain.net
Username: user@domain.net
password: correct password

(Same stuff that logs me into webmail)

Outgoing Mail Server
Host name: Mail.Domain.net (Tried smtp.domain.net)
Username: user@domain.net
password: correct password
Authentication: Password
Server Port: 587 (I don't know how correct this is, This is the port my old website host told me)

No SSL stuff, I'm very new to the whole VPS thing and panels, I appreciate all the support I've gotten so far.
