iPhone and iPad are not sending emails
My iPhone and my iPad do not send emails. I've searched the web and followed some suggestions, including deleting and adding back the email account and nothing fixed the problem
iPhone 15 Pro, iOS 26
Question marked as
What company is the provider of your email? For example, what domain is on the right side of the @ symbol (e.g. @yahoo.com, @icloud.com, @aol.com, @google.com, ...).
If you can receive but not send email on both devices, the my first guess is that the server configuration information that you are using is very old and includes unencrypted SMTP (over port 25 without SSL/TLS). Modern security best practices intended to prevent spamming mean that email server communications such as that are typically blocked by any sane ISP or network administrator.
If you let us know what your email domain name is then someone here can likely look up the correct modern server settings that will work for you (please don't post your actual email address).
