relaying access denied - proper SMTP authentication required
- Q: When trying to send email, I get relaying access denied (relay denied, unable to relay) error message.
- A: For security reasons many SMTP servers, especially outside internal network, reject all unrecognized connections and display relaying denied message.
To get access user has to authenticate with SMTP, otherwise one of the following error messages will be displayed:
Couldn't send message, Server Response: 550 Relaying is prohibited.Couldn't send message, Server Response: 550 5.7.1 Unable to relay.Couldn't send message, Server Response: 550 Relaying denied.Couldn't send message, Server Response: 554 Relay access denied.
Relaying access denied error message text may differ among SMTP server software. However, the solution is to authenticate with SMTP server, using -AUTH parameter of Febooti Command line email.
When proper SMTP authentication is required, try using -AUTH AUTO switch for automatic authentication method detection. Also, user name and password has to be provided, using -USER and -PASS parameters (if NTLM authentication is used, no username and password is necessary).
C:\>febootimail -SERVER smtp.server.com -FROM john@sender.com -TO jack@recipient.com -MSG DOS prompt SMTP authentication -AUTH AUTO -USERNAME ******** -PASSWORD ********This should solve the issue with SMTP relaying access denied error.
