Sender address is wrong

Hello,

I builded a CF7 form. I receive the mails but the sender is always me (= my personal email address) and not the [email protected]. While I’m making tests with dummy informations and a different email address than my personal one.

• Is there something that I missed while configurating?
• Do you think there may be a relation with the host?

The form:

<label>Prénom <span class="required">*</span>
[text* firstname]</label>

<label>Nom <span class="required">*</span>
[text* lastname]</label>

<label>E-mail <span class="required">*</span>
[email* mail]</label>

<label>Message <span class="required">*</span>
[textarea* msg placeholder "Tapez votre message ici"]</label>

[submit "Envoyer"]

Also, in the “To” field I can only put a gmail/hotmail/… address. The redirection like [email protected] doesn’t work. The mails are never send in this case.
And I can’t put [firstname] [lastname] <[mail]> in the “From” field either 🙁

• How to solved this too?

Thanks !
