	-s "With attachment" \
	-t "Please see attachment" \

    update / upgrade

    update only checks whether a newer Release of unimails/unimail-client is available; it does not install anything:

    unimail-client update

    upgrade checks the latest Release, downloads the asset matching the current operating system and CPU architecture, and replaces the currently running executable:

    unimail-client upgrade

    Auto upgrade is only available for direct Release downloads or locally built binaries. Package-manager installations, such as APT/PPA, Winget, or Homebrew builds, disable upgrade and should be upgraded through the same package manager; update remains available for checking releases.

    Examples

    Send plain text email

    unimail-client -r a@example.com -s "Test" -t "Hello"

    Send HTML email

    unimail-client --receiver a@example.com --subject "Test" --html "<h1>Hello</h1>"

    Send email with attachments

    unimail-client \
	-r a@example.com \
	-s "Report" \
	-t "Please check the attachment" \
	--file "report.pdf;./report.pdf"
