Security tuning =============== Dovecot is pretty secure out-of-the box. It uses multiple processes and privilege separation to isolate different parts from each others in case a security hole is found from one part. Some things you can do more: * Allocate each user their own UID and GID (see <UserIds.txt>) * Use a separate /dovecot-auth/ user for authentication process (see <UserIds.txt>) * You can chroot authentication and mail processes (see <Chrooting.txt>) * Compiling Dovecot with garbage collection ('--with-gc' configure option) fixes at least in theory any security holes caused by double free()s. However this hasn't been tested much and there may be problems. * There are some security related SSL settings (see <SSL.DovecotConfiguration.txt>) * Set 'first/last_valid_uid/gid' settings to contain only the range actually used by mail processes (This file was created from the wiki on 2018-02-28 04:42)
