TS3899 iPhone 4s IO6; Emails won't send from any account when they have images attached..

Question

Since upgrading to IO6, my phone has been struggling to send emails.. The problem is at its worst when I attach images.  I have three accounts (aol, gmail and ME) on the phone and the issue affects all of them.  I have rebooted the phone / deleted and re-installed the accounts and the problem persits..
After much presistance most emails will go through, but it can take hours to get them to send..
The issue was not present with the previous software..
Any help would be much appreciated as I need to send photos on a daily basis !!

Answer 1

You may want to delete the email account and try setting it up again. Once you have deleted it, re-start your phone.
Set it up manually and do not use the wizard.
It is best to go through settings >mail contacts, calendars > add account… > don’t choose the BT or BTYahoo option, tap the ‘other’ option from the bottom of the list > Add Mail Account and enter the following details:
Name – it can be anything you want, but usually your real name is preferable
Address – your full BT Internet email address
Password – your email account password
Description – this can be used if you have more than one email account on the device but put something like ‘work’ or  ‘BT Internet
Press “Next” and allow the verification (this may take a few minutes)
On the next screen it will want you to input incoming and outgoing mail server details:
Tap ‘IMAP’ at the top,
Incoming mail server settings:
Host name: mail.btinternet.com
Username: your full  BT Internet email address
Password: your email account password
Outgoing mail server settings:
Host name: mail.btinternet.com
Username: your full BT Internet email address
Password: your email account password
Press ‘next’
Slide the notes and mail to be ‘on’ and press ‘save’ in the top-right
Check your email on the device and see if it is working. Try sending yourself a message and see if it arrives. If messages are not able to send do the following:
Additional setting changes
Go to Settings > Mail, Contacts, Calendars > tap your BT email account > a window will appear, tap on your email address > scroll down to the bottom of the window and tap where it says ‘SMTP’ > tap the primary server (which should be mail.btinternet.com) >make sure the following is on or enabled:
‘Use SSL’ should be ‘ON’
Authentication should be ‘password’
Server port should be ‘465’
Press ‘done’ in the top-right
Now do back to your emails and see if you can send
