My e-mail client can't connect to your SMTP server.

If your e-mail client gives you an error that says, it can't connect to the mail server, your ISP/network may be implementing port 25 blocking.

Many ISPs have begun blocking access to third-party SMTP (outgoing mail) servers. Please consult with your ISP. Or you can try with port no. 26 instead of port 25.
