I am connected to the network of the mail server using a vpn, so connexion can be a little bit longer.

When I post a new comment on a blog post, there is no visual information telling me to wait, and in my last test, it lasted 2 minutes.

There sould be a wait message, and emails should be added in a queue so the result will be send to the visitor quickly.

This is also a problem when validating comments (no visual info about "something is working" and the request can be very long for each validation)
