For the "security warning at the top of the email", I think using your registrar SMTP with SSL (in general port 465), username and password should be good.

Hi, I have a little problem with the wiki.
The cache break the code colorization, so when I empty cache and reload page, it's work. But when a re-reload page there is no color on code and a bad spacing between lines appear for 7 days.
