Section mail - Debian Package: xfaces

 XFaces is a program that will display an image for each
 piece of mail in your mail box. This lets you know at a
 glance who you have mail from. XFaces starts out (when you
 have no mail) looking like a color xbiff. As you receive
 mail XFaces becomes a column of mail images. Some of XFaces
 features:
 .
 - Both mono and color images.
 .
 - Optional Shaped window support with both xpm and xbm.
 .
 - Sound support using the NetAudio protocol. The NetAudio server
 currently supports Sun's SparcStation (SunOS 4.1.X and Solaris 2.2),
 SGI's Indigo and NCD MCX X terminals running NCDware 3.1 or later.
 .
 - Face images can be "compressed" so that each image will only
 show up once on your display. This way, if you receive 30 messages
 from one user, list or whatever the image will only show up once.
 .
 - You can use regular expressions to search any headers to choose
 images and sounds or ignore that mail message completely. This
 lets you specify an image/sound for mail that comes from a
 mailing list or ignore mail that you have already seen but
 left in your system mailbox.
 .
 - Compatibility support for Rich Burridge's faces program. This
 includes the ability to run user command to generate the image
 list.
 .
 - Support for POP mailboxes.
 .
 - XFaces can kick off shell commands based upon mailbox
 contents.  You could have yourself paged when a high priority
 item needs your attention.
 .
 - XFaces can run external filters to convert images into Xpm
 so that image formats that XFaces does not understand can
 be used.
 .
 - The annotations for mail items include username, hostname,
 count, user@host, the contents of any header.
