Updated system-switch-mail packages that fix one bug are now available for Red Hat Enterprise Linux 5.
The system-switch-mail utility is the Mail Transport Agent Switcher. It enables users to easily switch between various mail transport agents.
Prior to this update system-switch-mail contained the shebang line, "#!/usr/bin/env python". This made it difficult to install alternative versions of Python on the system. With this update the shebang lines in Python executables have been changed to, "#!/usr/bin/python", to ensure the Python interpreter installed on the system is used.
All users of system-switch-mail are advised to upgrade to these updated packages, which resolve this issue.
