Q: I try to apply demo license by our own domain, but always get error 550 5.5.1 Protocol error
A: When requesting a demo license with automatic forms in our website, please check that you spell the email address The basic reason for SMTP error RCPT TO 550 5.1.1 is a typo in the recipient’s email address, such as a missed or duplicated character.
Try another email, maybe in another domain. Or contact us through online chat to get a demo license.
