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), connect outlook cannot connect to outgoing smtp server comcast error 10060', Port: 25, Secure(SSL): No, Server Error: 421, Error Number: 0x800CCC67 while he was outlook cannot connect to outgoing smtp server godaddy trying to send some emails with his Outlook Express mail client on his desktop computer running Windows XP, since he is not thunderbird cannot connect smtp server 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. After I have asked http://answers.microsoft.com/en-us/msoffice/forum/msoffice_outlook-mso_other/error-10060-cannot-connect-to-outgoing-smtp-server/34708df1-ab69-49df-9bd8-bb21025fe657 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 through a BTC ADSL see http://www.pc-freak.net/blog/what-causes-the-421-cannot-connect-to-smtp-server-error-and-a-quick-work-around/ 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.

I don't use Outlook but suggest that you try the following:Open Outlook click on File > Account Settings > Email > ‘More Settings > Outgoing Server and check the option which reads ‘My outgoing server requires authentication’.Apply the settings and restart Outlook.

For receiving email there is nothing wrong.This is the error message:Code: Select allAn error occurred sending mail: The mail server sent an incorrect greeting: Cannot connect to SMTP server x.x.x.x (x.x.x.x:25), Connect error 10060First of all I thought the anti virus is the culprit. But after disabling it for a moment, the email still cannot be sent.The setting of the SMTP server (in Thunderbird) is as such:- Server name: mail.mydomain.com- Port: 25- Connection security: noneI wonder if this is related to Mail Enable. If yes, how to solve it?(I try changing the SMTP server using the one from the ISP (using port 587), and the email then delivered)I believe the change above is temporarily solved the problem, that's why I asked on this forum to make sure.Please advise.Regards.
