type SendOption func(*mailSendOpt)
SendOption is a function to set option for Mail.Send
func WithEmailRequireTLS ¶ added in v6.3.0
func WithEmailRequireTLS(tlsConfig ...*tls.Config) SendOption
WithEmailRequireTLS enforces an encrypted SMTP connection and refuses to fall back to plaintext.
Security: by default delivery uses gomail's opportunistic STARTTLS. A network attacker can defeat that by stripping the STARTTLS capability from the server's EHLO response, causing credentials and message content to be transmitted in cleartext (a STARTTLS-stripping downgrade attack). With this option set, Send requires encryption: for the conventional implicit-TLS port 465 it dials directly over TLS, and for any other port it requires the server to advertise STARTTLS and aborts WITHOUT sending if it does not.
An optional *tls.Config may be supplied; when nil a config using the SMTP host as ServerName and a TLS 1.2 minimum is used.
If WithMailSendDialer is also provided, the explicitly supplied dialer takes precedence and this option has no effect.
func WithMailSendDialer ¶
func WithMailSendDialer(dialerFact func(host string, port int, username, passwd string) Sender) SendOption
WithMailSendDialer set gomail.Dialer
