Email problems sending messages with IPhone 6

Delete the email accounts off the phone. Then re-input them.

You are correct in that it is related to the SMTP server. That is the side of email that sends messages. If this is happening regularly, what email provider are you using? Have you attempted to remove the mail account from the phone and entering it again? This may fix the issue where the password is failing.

I have the same problem.

I have setup a new iPhone 6 using the restore from iTunes to import all the settings from my old iPhone 5.

Note that the iPhone 5 was running iOS6 and the iPhone 6 was on iOS8.00

Now on the new iPhone 6 all the emails arrive fine but I can't send anything from any of my accounts. For each one (and each one was set up to use a different SMTP) I get the same error "cannot send mail - the username or password for SMTP:username@mail.domain.com is incorrect" (I have not reprinted here my username and domain, but the error message shows the correct ones).

Note that I still have the iPhone 5 and this can still send mail without any problem. I have checked the settings and they are exactly the same.

My mail server is IMAP, it uses the name mail.domain.com instead of the classic smtp.domain.com, it's on port 25, there is no SSL but it is password protected with the same password used for receiving mail. I have checked all these settings and they are exactly the same for iPhone 5 and iPhone 6.

I am currently having to go back to use the iPhone 5 and leave the new one home for watching videos with wi-fi !!

It makes for a great laugh from anyone that asks me about the new phone.

P.S. the phone is now running iOS 8.02 - I can't say if the issue was already there with 8.00, I have had it for just a couple of days on 8.00 and I don't remember trying to send an email from that, but I can't be sure.

Generally, restoring from a backup and/or syncing with iTunes does not bring over the password, that is a safety measure. Go back into the account and verify that you have the username and password entered in all sections. If you are not sure, take the time to remove the account and add it back again, ensuring that you have all of the correct settings to enter before beginning. After entering the account it should verify, and if it does then it should work.

Solved.

It is correct that the restore doesn't copy the password, so I had already re-entered the password. But restore had also switched back the SSL to the default value on.

My server is not on SSL so I had to switch it off.

What was confusing is that now, having the correct password already entered, and then switching off SSL on SMTP (there is also a separate SSL setting for receiving mail) it kept giving the error message about username or password incorrect.

Apparently it was necessary to enter the password again - even though it appeared to be already there - and this time it worked.

The same sequence had to be repeated for the other accounts.

If I had to do it again, the sequence is: go to SMTP settings, switch off SSL, then enter the correct password, then click on DONE.

Entering the password first, clicking on DONE, then switching SSL off, and clicking on DONE would not work.

OK I have changed from the iPhone 5S to iPhone 6+ and restored from iCloud and all my email accounts would receive but not send. I checked and all my SMTP servers were set to "Off" as a result of the restore.

So what just worked for me was to go to: settings/mail,contacts,calendars and select the email account you are having problems with the tap the user name or account name then select "outgoing mail server" (again tap user name or email name") and you will see a list of all SMTP servers you have set up, if you have more than one. Select the server(s) you want to use and change to "on".

As a result all my emails stuck in the outbox sent!

Hi,

I just spent hours putting in the smtp server settings on my new iPhone 6. Your suggestion fixed the problem immediately, i.e. the order of turning SSL on and off and then putting in the pw. It's utterly a bizarre requirement. Thanks

Interesting that you responded to me, but I was not asking a question. And, in addition, no where in this post did anyone state they were using Cox mail accounts. I can appreciate your taking the time to post this information, however settings for Cox email would not be relevant for anyone no using that system. Each SMTP server for individual email providers is different.

Unbelieveable! This actually seems to have corrected my issue. How on earth would a normal "Joe" even begin to figure this out???!!!! Fingers crossed this stays fixed!

Thank you... I was going in circles with this and my email host. This worked like a charm. Following the sequence as you've listed is vital to the success of this. Thanks again!

Thanks for taking the time to write this out - this is exactly the problem I am experiencing with my wife's iPhone 6 (and yes I have Cox email) - will give this a shot and hopefully my life will go back to normal!

Thank you so much, after spending hours on SMTP and various screens, talking to an IT guy who did not know, your post solved my issue in 3 minutes. Thanks again.
