cannot receive mail in my live mail account

I had to establish a new email address as Optimum was bought by Charter. I can receive emails but cannot send mail.  I get error ID 0x800CCCoE with socket error 10060. I have used the following specs to fill in the blanks for new account. These were received from Charter. 1) Server type:  IMAP

2) IMAP Incoming mail server: IMAP.charter.net   Port 143  3) Outgoing server information:  smtp.charter.net port 25.  I checked 'remember this password' and 'manually configure server settings'. Please help.
