I've been using the Contact Form 7, but I had one problem:
When I sent a message to my default "from e-mail" (email@example.com), I hadn't recieve anything, but If I sent the message manually, I did recieve it.
Also if I change "firstname.lastname@example.org" to "email@example.com" (my personal mail)
It seems It doesn't work with my domain mail.
I've talked with the Hosting but everything is OK..
Anyone knows something like this?
