According to squirrelmail.org the problem is the lack of a trailing / in the config file but a symlink also fixes the problem (thats what I always did)
I've had that problem with SM 1.2.10 with Mandrake 9.0. (the ../data/default_pref unavailable). Well the problem is in the config ... Run conf.pl in the config dir In the "General Options" be sure to have a directory that end with a / ex: /var/lib/squirrelmail/prefs/ ( The default dir in my RPM (Mandrake) was "/var/lib/squirrelmail/prefs") quote from: http://www.squirrelmail.org/wiki/en_US/DataPermission tjfontaine
