You could use the octal mode: chmod 1777 /var/spool/mail. The leading
'1' turns on the sticky bit.

Use either "chmod +t" or "chmod 1xxx" where xxx is the normal
absolute permissions (eg, 755 for rwxr-xr-x).


As seen in the absolute mode, the sticky bit isn't part of the others permissions, but rather a part of a triple which includes setuid and setgid. Each of these bits affects the entire file, not a specific set of permissions. They are shown within the permissions for user, group, and others in an 'ls -l' merely as shorthand. That's why "chmod o+t" doesn't work.
