Overview ¶
Package smtp implements the Simple Mail Transfer Protocol as defined in RFC 5321. It also implements the following extensions:
8BITMIME RFC 1652 AUTH RFC 2554 STARTTLS RFC 3207
Additional extensions may be handled by clients.
The smtp package is frozen and is not accepting new features. Some external packages provide more functionality. See:
https://godoc.org/?q=smtp

Functions ¶
Types ¶
type Client ¶
type Client struct {
// Text is the textproto.Conn used by the Client. It is exported to allow for
// clients to add extensions.
Text *textproto.Conn
// contains filtered or unexported fields
}
A Client represents a client connection to an SMTP server.
func NewClient ¶
NewClient returns a new Client using an existing connection and host as a server name to be used when authenticating.
func (*Client) Data ¶
func (c *Client) Data() (io.WriteCloser, error)
Data issues a DATA command to the server and returns a writer that can be used to write the mail headers and body. The caller should close the writer before calling any more methods on c. A call to Data must be preceded by one or more calls to Rcpt.
func (*Client) Extension ¶
Extension reports whether an extension is support by the server. The extension name is case-insensitive. If the extension is supported, Extension also returns a string that contains any parameters the server specifies for the extension.
func (*Client) Hello ¶
Hello sends a HELO or EHLO to the server as the given host name. Calling this method is only necessary if the client needs control over the host name used. The client will introduce itself as "localhost" automatically otherwise. If Hello is called, it must be called before any of the other methods.
func (*Client) Mail ¶
Mail issues a MAIL command to the server using the provided email address. If the server supports the 8BITMIME extension, Mail adds the BODY=8BITMIME parameter. If the server supports the SMTPUTF8 extension, Mail adds the SMTPUTF8 parameter. This initiates a mail transaction and is followed by one or more Rcpt calls.
func (*Client) Noop ¶
Noop sends the NOOP command to the server. It does nothing but check that the connection to the server is okay.
func (*Client) Rcpt ¶
Rcpt issues a RCPT command to the server using the provided email address. A call to Rcpt must be preceded by a call to Mail and may be followed by a Data call or another Rcpt call.
func (*Client) Reset ¶
Reset sends the RSET command to the server, aborting the current mail transaction.
func (*Client) StartTLS ¶
StartTLS sends the STARTTLS command and encrypts all further communication. Only servers that advertise the STARTTLS extension support this function.
func (*Client) TLSConnectionState ¶
func (c *Client) TLSConnectionState() (state tls.ConnectionState, ok bool)
TLSConnectionState returns the client's TLS connection state. The return values are their zero values if StartTLS did not succeed.
