Cannot Send Email after Updating to iOS 7. Help!

Ever since I updated to iOS 7, I get an error when sending mail from my iphone.  The error is:

Cannot Send Mail - The Connection to the outgoing server "smpt.zoho.com" failed.  Additional Outgoing Mail Servers can be configured in Settings > Mail, Contacts, Calendars


I am able to receive mail, this worked fine before updating to the new iOS, and I have followed Zoho's directions for setting up email on iphone.  Everything is set up correctly.

Can anyone help with this?????
