Old settings were port 110 to receive, port 25 to send. New port settings might be 995 SSL to receive, 587 (or 465) SSL or TLS to send. You need to get these settings from your email supplier. Also look at Outgoing Authentication (also in Advanced Settings). You may need to provide an email address to authenticate the send. ....

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 error 10060', Port: 25, Secure(SSL): No, Server Error: 421, Error Number: 0x800CCC67 while 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. 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 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.

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
