说明
msmtp is a lightweight SMTP client for sending email from the command line. It works as a sendmail replacement, enabling scripts and applications to send mail through external SMTP servers. Configuration in ~/.msmtprc defines accounts with server settings, authentication, and TLS options. Multiple accounts can be configured for different mail servers or identities. Password handling supports several methods: plaintext (not recommended), passwordeval to run a command (e.g., password manager), or system keyring integration. TLS is supported via STARTTLS or direct TLS connection. Certificate verification can be configured to use system CA certificates or specific files. As a sendmail replacement, msmtp can be symlinked to /usr/sbin/sendmail, making it the default mail transport for the system. Many applications use sendmail for outgoing mail. Integration with mutt, git, and other tools is straightforward - they just need to know the sendmail path or can use msmtp directly.
