If I send something from http://www.inmotionhosting.com/support/community-support/email-client-setup/503-error-and-rejected-email web based email, it goes through fine. If I send it from my Outlook 2013, I get a system administrator email that says it's undeliverable "503 Valid RCPT command must precede DATA". I am pretty sure I have my Outlook settings correct. Any ideas? Thank you You must login before you can ask a follow up question. You must login before you can submit an answer. OTHER ANSWERS 0 scott Staff 39,903 Points 2015-01-19 1:28 pm EST Hello, Thank you for your 503 error question today. This is a common error when the outgoing email is not set up for authentication. You can check our article on Outlook 2013 email setup and look to about Step 7. There you will see the setting. Ensure that is enabled on your Outlook, regardless of version, and it should help.

The server returns the message: 503 This mail server requires authentication when attempting to send to a non-local e-mail address. Please check your mail 503 valid client settings or contact your administrator to verify that the domain or address is defined for this server. CAUSE Possible causes: Email client is not configured for SMTP authentication and the server is Firewall or email proxy software is preventing SMTP authentication from occurring Email client has incorrect credentials configured or does 503 valid rcpt not match server settings RESOLUTION Relay settings are defined under the properties of the SMTP connector in the MailEnable Administration program. The default setting is to only allow relay for authenticated senders. This requires that email clients have SMTP authentication enabled. This is done in Microsoft Outlook by the enabling the 'My server requires authentication' option for the account. Other email clients may have this worded differently. You can also add the connecting IP address to the list of addresses which are allowed to relay in the SMTP Relay options.

reply codesSometimes your SMTP server may return a particular error message. The problem is that it will generally be very cryptic, like "550 Requested action not taken: mailbox unavailable" or "421 Try again later". What does these numbers mean?First of all: not any reply code is an error. Sometimes it's just a response containing a detail about the server or an answer to a command. Secondly: any code consist of three digits, and each conveys a particular information. The first one defines whether the server has accepted the command, fulfilled an action, run into a temporary issue, encountered an error etc; the second and the third one refine the description further, stating if there's been a syntactic problem, or a connection trouble etc.Unfortunately, different servers sometimes use these codes in a different way, making the whole thing even more complicated... Anyhow, the most critical series of error messages is the 5xx one, and especially the ones from 550 to 559. In particular, you will probably get a lot of 550 SMTP error codes – that is, a problem that concerns the recipient's email address.Finally, remember that it's much easier to deal with these error codes if you choose to rely on a professional SMTP server that will help you solve any issue. turboSMTP, for instance, comes with a 24/7 customer support: you can try it free and forget once for all these issues.And here's a list of the main SMTP error or reply messages, with an explanation and a tip about what to do. CODEMEANINGHOW TO SOLVE IT / WHAT TO DO101The server is unable to connect.Try to change the server's name (maybe it was spelt incorrectly) or the connection port.111Connection refused or inability to open an SMTP stream.This error normally refers to a connection issue with the remote SMTP server, depending on firewalls or misspelled domains. Double-check all the configurations and in case ask your provider.211System status message or help reply.It comes with more information about the server.214A response to the HELP command.It contains information about your particular server, normally pointing to a FAQ page.220The server is ready.It's just a welcome message. Just read it and be happy that everything is working (so far)!221The server is closing its transmission channel. It can come with side messages like "Goodbye" or "Closing c
