# Mail counter statusbar item
# for irssi 0.8.1 by Timo Sirainen
#
# Maildir support added by Matti Hiljanen
# Multiple Maildir/mbox and customization support added by Joost Vunderink
# OLD mailtreatment switch added by Bart Matthaei.
# Improved some regexps in maildirmode by Bart Matthaei.
# Maildirmode regexps (hopefully) fixed for good by Matti Hiljanen.
#
# You can add any number of mailboxes or Maildirs to watch for new mail in.
# Give them any name and <name>:<count> will appear in your mail
# statusbar item, where <count> is the number of unread messages.
# If only 1 mailbox/Maildir is defined, the statusbar item will have the
# familiar form [Mail: <count>].
# If you set mail_show_message to ON, irssi will print a message in the
# active window whenever new mail arrives.
#
# Check /mailbox help for help.
