Hello

I have this error :
ERROR Send Email 3:58 Execute failed: Error while communicating with the smtp server: javax.mail.SendFailedException: Invalid Addresses;

nested exception is:

com.sun.mail.smtp.SMTPAddressFailedException: 454 4.7.1 email…]: Relay access denied

How can i fix this?
Thank you

You mail server does not allow relaying mails to a different domain. This can happen if you try to send mails without authentication.

Does your credential email address match the “From” email address? A mismatch between them could probably lead to an error like this as well.
