As said it depends:
- If you simply want to encrypt between a small number of sites use
enforced TLS with cert checking
- If you need encrypt mail traffic and others between a small number
of sites with trust relationship use some form of VPN
- If you need ad-hoc encryption of e-mail with a number of mail
recipients implement some form of PGP or S/MIME gateway

I can say it is not that hard to setup Djigzo and it provide a poliy
drive way to handle encryption and signing for e-mail.
