Iphone mail uses smtp server that doesn't exist
My iphone SE mail persistently uses an smtp server that isn't listed anywhere, but was used 2 iphones ago.
I've deleted the account and smtp servers multiple times.
There's just one main smtp server....no extras
everytime i try to send an email i get: username and password for smtp:mail06xxxxxxxx@authsmtp.Vodafone.nl is incorrect.
and vodafone isn't my provider anymore nor do i use vodafone's smtp server.
Anyone have any idea on how to tackle this ??
iPhone SE, iOS 9.3.1, null
