# 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.
