This is rather an interesting problem I encountered with a buddy of mine's computer.
It's not an urgent problem but I would like advice/solutions for it.
Yesterday his email was working fine, but today when he sends an email to a client it sends it, but its also placed in the junk email folder.
I told zone alarm that the items in the junk folder that he sent isnt junk so it then sent it to the inbox.
He has zone alarm firewall and avg free installed, he is very computer illiterate so I doubt it that he messed around with any settings on any of these products including outlook. Hopefully someone has a solution for it.

Also no email rules have been changed or modified.
