using one.com email address for wp mail smtp

To use a One.com email address with WP Mail SMTP, select the “Other SMTP” mailer, enter mailout.one.com for the SMTP Host, 587 for the port with TLS encryption (or 465 with SSL), use your full One.com email address as the username, and your email password as the password. Ensure that the “From Email” address in WP Mail SMTP matches your One.com email address and that authentication is enabled.
