SMTP problem ( same as codeigniter 3)

The Email class in CodeIgniter 4 is a barely-changed port from version 3. There is a complete rewrite in the works but for now it is likely any problems you had using the CI3 version will persist in CI4.
That said I use the Email class daily without trouble, so you might just need to give it some more effort.

I found the problem , It s a server problem about sender if i use a link as name the class ( or the server) dont send the mail
