Be prepared for a long, long journey.... setting up an email system with SMTP/
IMAP/Webmail using all the goodies SPF/SRS, BATV, DKIM, DNSSEC, TLS certs,
DANE, virusscanning, anti-spam Measures (possibly greylisting, classification,
RBLs, dnswl, ...), virtual domain handling, user auth from a directory,
automatical MUA configuration, backup of the mailstorage, asf. is rather
complex and time consuming. But it can be fun nevertheless... :-)
