lordshak3r on "[Plugin: Contact Form 7] Mail sent but not received"

Hi,

First of all, sorry for my English (I'm French)
I've got an issue with Contact Form 7, all mails are sent but I do not receive any of its.
I've already checked if my email was ok and it is.
I wonder if I neded to set registrar_global with on or off ? or anything else ?

Thanks for you help
