wp_mail contact forms taking 7 hours

The tried and tested Contact Form 7 plugin, on the tried and tested 2014 theme of a new WP installation takes7+ hours to get the email into my hosting providers inbox (godaddy hosting)

email address in question is user@domain.com. WP general settings have been changed so email reads that same addy. WP forgot password test at login does not email me with password.

I think on this installation the way wp_mail is trying to take information and pass it to the email server is causing an error.

Why would wp_mail email take 7 hours when mailing user@domain.com ?From an outlook.com addy or a hosting addy takes 2 seconds to send or recieve email to/from user@domain.com

I’m unsure whether the delay is related to why I’m not getting the wordpress change password email ‘at all’ or if I’m simply conflating and confusing the 7+ hour delay issue.

I’ve read a lot of info over the past 2 days and spent many hours.

A php wp_mail test script suggests wp_mail sends and gives no error. But WHAT it is sending may well be the issue.

The WP email (settings > general) was not user@domain.com when i opened the WP account.. could this be confusing WP mail to send email that cant be authenticated due to conflating the data?

The delay just seems bizarre. Any thoughts?
