 * Our enterprise environment does not use authentication for SMTP. I can’t add 
   the provider without it. Any suggestions, other than tell IT to do something 
   different.

 * Hello [@toddmckee](https://wordpress.org/support/users/toddmckee/) 
   _Thanks for
   reporting this. Right now our “Other SMTP” setup requires SMTP authentication(
   username/password), so unauthenticated corporate relays are not supported yet.
   We’re considering adding an optional “No authentication” mode for trusted internal
   SMTP relays._Best Regards.Pro Mail SMTP team
