# Mailbox format is determined by the 'mbox' and 'maildir'
# system USE flags.
#
# Mailbox path configuration denoted by the system USE
# flags.
#
# USE flag 'maildir' denotes ~/.maildir
# USE flag 'mbox' denotes /var/mail/username
#
# You can overwrite this by setting the POPA3D_HOME_MAILBOX
# environmental variable (see below) before emerge.
#
# Environmental variables.
#
# POPA3D_HOME_MAILBOX
#
# Overwrite the local user mailbox path. For example
# if you want qmail-styled ~/Mailbox you can set it
# to "Mailbox". For the traditional (although not in
# gentoo Maildir) set it to "Maildir".
#
# POPA3D_VIRTUAL_ONLY
#
# Set this field to "YES" if you dont want local users
# to have POP access. Setting this makes the POPA3D_HOME_MAILBOX
# variable effectively useless.
#
# POPA3D_VIRTUAL_HOME_PATH
#
# Set this field to the base virtual home path. For more information
# read the virtual guide here: http://forums.gentoo.org/viewtopic.php?t=82386

# Version 1.0 introduced some increased default values for a number of
# configuration paramaters. These values are way too high for most systems.
MAX_SESSIONS=100 # Default is 500
MAX_SESSIONS_PER_SOURCE=10 # Default is 50

MAX_MAILBOX_MESSAGES=100000 # Default is 2097152
