I was temporarilly using pine to retrieve my email, and upon exiting the

What are the implications of this, and won't 1777 make the folder more
vulnerable? My understanding was that if the SUID bit is turned
on for either U, G or O, that security is more at risk. Please
let me know what I should do...

Read the man page for chmod.

The suid and sgid bits mean something different on directories than on
files.  When set, they force all files created in that directory to be
owned by the owner of the directory.  Again ... see the man page for more
detail, as well as (I believe) a description of how this helps security.
