Since updating to iOS 9.2.1, I am unable to send emails when I want to.

Yesterday I updated to ios9.9.2.1. Since then, any emails I try to send fail, saying that my email address is invalid. Since I've been using it for about 20 years, I find this highly unlikely. Some emails go after a period, but that is no help when I want to send an urgent one. Does anyone else have this problem,? Anyone know why it is happening? I'd rather address the question to Apple directly, but can't find any route to do this - all they do is dump th new update on us and leave us to sort out the problems.

Not sure what email account you're using as you didn't state it.

1. would be make sure the account is set up correctly.

2. remove and reinstall the email account.

3. ask the email provider what the issue is.

Then I would double check that the setting for your outgoing mail server is correct.

Or contact Tesco.

The mail info is correct. Further checking has shown that emails without attachments go without problems, but those with attachments fail. This confirms email outgoing data is OK. I had sent a lot of emails with attachments immediately before updating the iOS, and all emails with attachments failed immediately afterwards. The only change was the update. The attachment size is within the limits of my provider, and similar emails work fine when sent from the laptop. I will contact my provider tomorrow, but still feel the iOS is faulty.

Close out of the mail app and double tap the home button and completely close out of the app. Then do a reset, no data loss. Hold down the home/sleep button together until you see the apple logo and then release, then wait for the device to boot back up. Then try sending an attachment again.

Is there an error message with the failure? Is that where you see "email address is invalid"?

That sounds absolutely like a credential issue with your outgoing mail server. Is it an IMAP account? Tesco's website doesn't really say if they use POP or IMAP.

If IMAP, your danger of losing email be removing and adding the account back should be nil.

The iOS merely provides data to Tesco's outgoing server. If the answers aren't what the server expect to hear, your outgoing mail might be refused or delayed. It sounds like that is the issue.

It's easy to blame the iOS. It's rarely accurate on email issues.

Your message proves it was a Tesco issue all along.

The iOS does not validate emails, so could not have possibly generated the error message. Tesco's servers validate email addresses and would be responsible for the error message "email address does not exist"

I'm not even going to comment on your theory that someone connected with writing the iOS read your message on the 8th and downloaded a secret fix to your device by the 10th.

I just upgraded to 9.2.1

I have six different accounts with different email providers using IMAP.

NEVER had a problem until now,

Different accounts will randomly fail to send mail. They get stuck in the outbox and will never send. All settings are correct. Sometimes it sends mail, and sometimes it doesn't.

Like getting new tires that can't hold air.

Doesnt make any sense to have a problem for something so basic and fundamental.
