Network unreachable error when sending mail from mutt

Hi all, I'm getting a "SMTP server problem Network is unreachable" "Error sending message, child exited 69 (Service unavailable.). " when trying to send a mail using mutt. When I used telnet smtp.gmail.com 587 or change the port to 465 I get Unable to connect to remote host: Network is unreachable. On trying openssl s_client -starttls smtp -crlf -connect smtp.gmail.com:587 I get --> connect: Connection timed out connect:errno=110 How do I solve this? Is there a problem with the firewall?
