Squirrelmail login failure
Since upgrading to ISPC 184.108.40.206, Squirrelmail has stopped working. As it is only occasionally used, it took some time for the problem to become apparent so this might not be due to the upgrade.
At the login page an error message - "You must be logged in to access this page. " is received after correct username and password.
An incorrect username or password results in "Unknown user or password incorrect."
Another post suggested that a reinstall of Postfix would be a cure but it didn't work for me.
