With php mail if that works for us, but we want to configure a specific account, do not send with php mail. Thank you for your response ---

@idgl for that you need to configure very well… since configuration is still not done that is why you get some error. ---

Hello I think the problem is that the mail server encrypts in 64base and the mail configuration for mautic does not accept it. It’s possible?
