Good day (in Paraguay), in my bad English but I'll try to explain. I installed zimbra sends and receives mail internally, but also receives external mail from certain domains only in the case of gmail says this "Delivery to the following recipient failed permanently", and traversed various forums and have not found the answer my limitation is the language I am using a translator
from already thank you very much for the help
Zimbra is configured and works internally but I can not receive external mail from some domains, in the case of gmail is the error Technical details of permanent failure:
Google tried to deliver your message, but it was rejected by the recipient domain. We recommend contacting the other email provider for further information about the cause of this error. The error that the other server returned was: 550 550-mail-yx0-f201.google.com [188.8.131.52] is currently not permitted to
550-relay through this server. Perhaps you have not logged into the pop/imap
550-server in the last 30 minutes or do not have SMTP Authentication turned on
550 in your email client. (state 14).
muchas gracias por su ayuda
