 * Hello, I have a problem, I cannot authenticate email since some mail servers 
   need the email name in punycodeo to authenticate when I try to put a letter ñ
   in punycode in From Email Address the plugin automatically translates that is,
   if I try to put [info@xn--castaa-0wa.com](https://wordpress.org/support/topic/punycode-problem/info@xn--castaa-0wa.com?output_format=md)
   in the email the plugin automatically leaves it as info@castaña.com and that 
   gives me problems with external email servers. Is there any way to fix it? Thank
   you.

 * Hi there [@powebdesign](https://wordpress.org/support/users/powebdesign/),
 * Thanks for the response. I checked in with our development team about this. We
   are passing a punycode-encoded value to the SendGrid API. This issue may be on
   their side of things. Try reaching out to SendGrid’s support team about the issue
   so they can take a look.
 * I hope that helps! Have a great day! 🙂
