KB: 04112013-001: Mail admin installer because libmail-sender-perl is not found

Symptom

When launched Mail admin installer, it stops and fails reporting that libmail-sender-perl package isn’t found.

Affected releases

Debian Lenny (5.0), Debian Squeeze (6.0), Debian Wheezy (7.0)

Solution

1. Update your /etc/apt/sources.list to include “non-free” declaration to default source of packages. A working example should like like:

   deb http://ftp.es.debian.org/debian/ squeeze main non-free

2. After that, restart the installer again.
