Sending emails on iPhone going to outbox

Mainmanxx — Thu, 11 Jun 2026 20:29:28 GMT

All my Sendi emails on iPhone go to outbox.

I’ve gone through the app with Apple and BT chat service, deleted and added the email account, but still no success.

IMAP and STMP settings appear to be correct.

The problem only started about 2 months ago.

Many thanks

What happens if you send an email using webmail instead of your email app?

Are the emails stuck in the outbox or do the actually send?

When you log onto webmail have you checked in the settings which you will find by clicking on your username at the righthand side that the box to save sent emails is ticked.

Have you tried a different email app?

Emails do send from browser and BT Mail app.

When I send from iPhone Mail they go straight to outbox when on WiFi - if I turn off WiFi and use mobile data the email sends

Try a factory reset of your BT hub by pressing the recessed button on the rear for about 30 seconds.

I’ve reset the router, Fibrus Nokia, but email still going to outbox.

Message:

Cannot Send Mail

The sender address was invalid.

Welcome to the Community, @Mainmanxx

Are you noticing the same issues if you try sending using a different WiFi connection, or use mobile data?

If these are fine, it's worth leaving your router unplugged for around 30 minutes so a new dynamic IP can be assigned to your connection.

Are you presently a BT Broadband customer or are you paying for your email through a BT Premium email account.

I suspect that your Fibrus Nokia router is blocking the port or you are using the wrong settings.
