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 error 421 4.3.2 service not available 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 error 421 service not available 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, http://www.inmotionhosting.com/support/email/bounceback-errors/email-error-421 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 http://www.serversmtp.com/en/smtp-error 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.

not send your message. Error 421." - Meaning of the Numbers Have you ever tried wondering what the codes actually mean? Or have you thought, if these numbers do make some http://msexchangeguru.com/2011/08/18/errors/ sense? Or if they might mean something which could help you identify with http://productforums.google.com/d/topic/gmail/2Zk4wBymJ04 the issue. Very often you encounter this in your mailbox. I intend just giving a small heads-up in understanding the meaning or interpreting the error codes which might help in making sense as to where the trouble could be. Primarily you will get the error code with three numbers as I showed error 421 above Error 421. First Number: This lets you know whether the server has accepted the command and was capable to handle it or not. Let me address you the possible meanings of the first number in the error now. 1: The server has taken the command, but it's not executing it. Here you need a confirmation message. 2: The server was able to complete service not available the task. 3: The server was able to understand the request but feels it needs more information to complete it. 4: The server faces a temporary failure here. If you try executing the command again, it may complete. At times, mail servers use such temporary failures to keep security higher. 5: The server actually has the error and you should attempt it. Second Number: This gives a little more information. Let me address you the possible meanings of the second number in the error now: 0: This indicates that a syntax error has taken place. 1: This indicates an informational reply, for example to a HELP request. 2: This indicates your connection status. 3 and 4 are unspecified. 5: This indicates your status of the mail system as a whole and the mail server in particular. Third Number: The last number is the key. It pertains more to mail transfer status. This actually relates to the detailed list of ESMTP server response codes, as laid down in RFC 821 and later extensions. 211 - This indicates a system status message. 214 - This indicates that a help message for a human reader follows. 220 - This indicates t
