Mail uses two different network paths for its processing.
Receiving mail uses POP or IMAP, with its server specification and credentials, while sending mail uses SMTP or a variant port and a (potentially different) server specification and credentials.
Here, your specification of the SMTP (sending) server - username, password, server host address, port, whether SSL is used or not - is likely incorrect.
Less likely but possible, you're using port 25 for sending, and a firewall is blocking that access. Most ISPs now allow what's called an SMTP submission port, TCP port 587, and you'll want to use that if it's available.
The Connection Doctor (Mail.app > Window > Connection Doctor) will likely confirm the configuration error.
Verify the necessary SMTP send-related settings with your mail ISP provider's support pages, or directly with the support organization.
