# High-Security mode. Dovecot default setting.
#
# It works by using a new imap-login or pop3-login process for each
# incoming connection. Since the processes run in a highly restricted
# chroot, running each connection in a separate process means that in
# case there is a security hole in Dovecot's pre-authentication code
# or in the SSL library, the attacker can't see other users'
# connections and can't really do anything destructive.

# High-Performance mode.
#
# It works by using a number of long running login processes,
# each handling a number of connections. This loses much of

# in case of a security hole the attacker is now able to see
# other users logging in and steal their passwords.

Tip: Use camelCasing e.g. ProjME to search for ProjectModifiedEvent.java.
Tip: Filter by extension type e.g. /repo .js to search for all .js files in the /repo directory.
Tip: Separate your search with spaces e.g. /ssh pom.xml to search for src/ssh/pom.xml.
Tip: Use ↑ and ↓ arrow keys to navigate and return to view the file.
Tip: You can also navigate files with Ctrl+j (next) and Ctrl+k (previous) and view the file with Ctrl+o.
Tip: You can also navigate files with Alt+j (next) and Alt+k (previous) and view the file with Alt+o.
