fex depends on sendmail binary

[Jim Salter]

No mail-related packages are listed as dependencies, but the fex server fails to produce output to a standard web browser if you don't have a sendmail binary available. Chromium for example says "the connection was interrupted" with no further detail; I only figured out what was going on because I did telnet localhost 8888 - that way, I could see

me@banshee:~$ telnet localhost 8888
Trying 127.0.0.1...
Connected to localhost.
Escape character is '^]'.
/usr/share/fex/bin/fexsrv: found no sendmail

I then did

me@banshee:~$ sudo apt-get install postfix mailutils

and after installing postfix and mailutils, browsing to localhost:8888 in a standard browser worked as expected.

Versions of Ubuntu and Fex installed as follows:

me@banshee:~$ lsb_release -rd
Description: Ubuntu 11.10
Release: 11.10

me@banshee:~$ apt-cache policy fex
