Outlook Error 421 Too Many Messages
error mentioned in the subject line - cannot connect to SMTP / error 421 / 0x8004219. I could still receive mail without a problem. I had made no changes to the set up at all (same setup I've had for years, through multiple ISP changes), but I have changed my ISP in the last month. I hadn't sent any mail since changing broadband provider until last week. My Mail Provider settings 421 cannot connect to smtp outlook 2007 are: mail.freenetname.co.uk smtpmail.freenetname.co.uk Outgoing mail requires authentication Incoming server - port 110 Outgoing server - port 25 I am still able to use these settings on my mobile, as long as I'm not using my home wireless / broadband to connect. If I use wireless, mail will not send. I had run a repair on the PST file, and had played with settings in Avast - 2 potential solutions, which didn't make a difference, so I contacted my ISP today. After a bit of investigation, she made a change to my outgoing mail server, which is now: smtp.orangehome.co.uk untick outgoing mail requires authentication and now mail works. and I don't understand why! Surely my mail settings are governed by my mail provider, not my ISP? Otherwise they wouldn't still work on my phone? Is my mail now being sent via Orange / EE, rather than via my mail provider?? Will my mail still work on my mobile phone if I change the outgoing server to Orange? I'm confused!!!!!! Can anyone help??

These should usually be resolved automatically, and you should receive a final bounce-back message if the message completely fails. You usually would not receive a bounce-back message for this type of error. If your message is going to be delayed more than 24 hours, then sometimes a "delivery has been delayed" soft bounce will be returned to you, to let you know that the delivery has ye
A colleague of mine has encounters errors like: An unknown error has occurred. Account: ‘mail.different.bg', Server: ‘mail.different.bg', Protocol: SMTP, Server Response: ‘421 Cannot connect to SMTP server 212.70.124.241 (212.70.124.241:25), http://www.pc-freak.net/blog/what-causes-the-421-cannot-connect-to-smtp-server-error-and-a-quick-work-around/ connect error 10060', Port: 25, Secure(SSL): No, Server Error: 421, Error Number: 0x800CCC67 while http://www.serversmtp.com/en/smtp-error he was trying to send some emails with his Outlook Express mail client on his desktop computer running Windows XP, since he is not too much computer literate he contacted me for help on what is causing the error and how he can get through the issue and send the prepared emails to the destinations ASAP. error 421 After I have asked him a few questions necessary to better understand the status of the problem and where does it originated I have come to the conclusion that it's very likely that his outgoing SMTP port (25) outgoing TCP/IP traffic passing through the Internet Service Provider is filtered. When the 421 Cannot connect to SMTP server problem occured, he was actually in his parents house provided with an internet connection 421 cannot connect through a BTC ADSL see BTC (Vivacom)'s ADSL page for reference I have instructed my friend to try connecting to the SMTP (25) port of the questionable email server using window's telnet client i order to check if my assumption that the outoging SMTP 25 port traffic is filtered. I instructed him to issue a command like which is so common this days and it's not news to the Sysadmins out there: cmd> telnet mail.server.net 25 This prooved my theory that the 421 Cannot connect to SMTP server was caused by a filtered traffic on the outgoing network STMP port (25). Some Internet Providers out there has that annoying practice of filtering the outgoing SMTP connections, because they couldn't deal with infected Windows computers who start acting as a SPAM networks in another more clever way, however I should admit this is pretty dumb, since it creates numerous problems to the end user like in this particular case. The temporary work around for him that I suggested was to use the mail server Webmail Interface before he moves back with his notebook back to his ISP at home which doesn't include such a foolish way to filter spammers.

Tweet If you're new here, you mareply 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 connection".The mailing session is going to end, which simply means that all messages have been processed.250Its typical side message is "Requested mail action okay completed": meaning that the server has transmit
