Description:
WindowMaker docklet watching your inbox
wmail is a Window Maker docklet watching your inbox, which is either a ordinary mbox or a directory conforming to qmails Maildir format. It provides a nice little GUI displaying some useful pieces of information about your inbox (as many other nice wm-apps doing nearly the same thing...). Per default it uses the $MAIL environment-variable to locate the inbox you are using, other mailing mechanisms like POP or IMAP are not supported - use a tool like fetchmail to retrieve POP- or IMAP-based mail.
