Delete SMTP Servers on iOS 13.2.3

Hi HRLaughed,

Thank you for using the Apple Support Communities! I understand you would like more information on deleting the SMTP server within iOS. I can provide you information that can help address this question.

If you are having an issue sending or receiving emails with an additional email account set up on your iPhone, check out these steps: If you can’t send or receive emails on your iPhone, iPad, or iPod touch - Apple Support. Within this article, the section titled, 'Check your Mail settings' leads you to how to check the SMTP (Outgoing Mail Server). You may have access to manipulate the SMTP when you tap on it, however it may vary from one email provider to another. Apple recommends using the Mail Settings Lookup tool to ensure you have accurate settings entered for your account: Mail Settings Lookup.

Best regards.
