how to delete an unlisted smtp server
I am using a new iPhone 6 running 8.3, which insists in using an smtp server which does not even appear in the smtp server list; this ghost smtp server was used two iPhones ago, and it somehow found its way onto the new iPhone.
I have seen the same question asked in several forums but never saw an answer to it.
I will appreciate any help regarding this.
iPhone 6, iOS 8.3
