Hello, you will need a SMTP server like Postfix or OpenSMTPD. You will 
also need to care with DKIM signing and SPF in your DNS. By running your 
own mail server you may also have problems to send mails to big 
companies like gmail, hotmail, yahoo etc... because they tend to 
blacklist large range of IP and it's hard to get removed on this list.

Also, you will have to provide IMAP(S) (+ POP(S) if you want) with 
dovecot.

If you need a webmail, see rainloop which is in PHP and act much like a 
dumb imap client from the web very little code on the server, or 
roundcube but this one needs more configuration and requires server side 
resources (caching, saving data etc..).

Later you may need to fight against spam with greylisting and 
spamassassin.

Running a mail server nowadays isn't very straightforward :(
