A script designed to automate postfix, dovecot instalation and configuration on ArchLinux. The script is aimed at creating a configuration that applies to most users' needs. I've tried to secure postfix and dovecot with the best practices I found online.

If any improvements come to mind please feel free to share.

Features:

-Postfix configured with STARTTLS on port 25 and 587

-Dovecot configured with STARTTLS on port 993 and SSL/TLS on 143

-Generation of self signed SSL certificate

-Protection against #POODLE, #FREAK/Logjam attacks by using 2048 bit DH group for both postfix and dovecot

-Configuration of virtual users, encrypted passwords

-Automatic folder creation and subscription: Sent, Drafts, Junk, Trash; for Dovecot
