[monitoring-like] would like to be warned when I have mail (fetchmail -c)

[Thomas Baruchel]

Hi,

I have an IMAP mailbox, but I use "fetchmail -c" in order to know if I have
new mail or not (below is the description for this option). I would like
this command to be run periodically (OK, that can be done through a
background process) and tell screen when I have new mail in order to
be warned (message in the status line would be great). But I couldn't
see in 'man screen' anything like that tough a reference to

which let me think someone may be able to help me...
