I am having issues with email addresses that include a foreign country. As an example, opening a ticket with the country address on the end: plage@xxxxx.com.br, results in the error message below. The ticket is still entered into the system, but the end user does not receive any confirmation messages and when you post a reply or close the ticket, the same error occurs.
Mailer Error: Language string failed to load: recipients_failedplage@credigy.com.br
Any help is appreciated.
