If I use pop3/imap to read my gmail via a desktop client can I also set it to show emails that google automatically puts into the spam folder?
If you need to access spam messages using pop3, you can create a filter to never place e-mail in the spam folder. According to http://aaron-kelley.net/blog/2008/08/disable-gmail-spam-filter-include-spam-in-pop3-download/
- Go to gmail.com
- Create a new filter
- Type * in the From field
- In the next screen, select "Never send it to spam"
- POP3 now downloads spam too
