I have a problem when trying to send an email through php using the function: mail ();
The problem is that more than 30 minutes have passed and no email has arrived, I have searched for information about it and I have noticed that a server is used for sending emails (eg SMTP). Therefore I do not know if in IBM Cloud it is managed that same (omitting the "SendGrid" service).
To this comes my doubt, should configure said server to be able to use the mail function (); ?
Thanks for your comments ...
