Class Netsmtp.client

class client : Netchannels.in_obj_channel -> Netchannels.out_obj_channel -> object .. end

method helo : ?host:string -> unit -> string list

Sends an EHLO command to the server. The optional argument ?host defaults to the default hostname of the machine. This function returns the ESMTP lines returned by the server.

If EHLO is not supported, the method automatically falls back to HELO.

EHLO is specified in RFC 1869.

method helo_response : string list

The response from the last HELO or EHLO

method auth : Netsys_sasl.sasl_mechanism ->
string ->
string -> Netsys_sasl.credentials -> (string * string * bool) list -> unit

auth mech user authz creds params: Performs a SASL authentication using the AUTH command. See Netsys_sasl.Client.create_session for details.


client # auth
  (module Netmech_digest_sasl.DIGEST_MD5)
  [ "password", "sEcReT", [] ]
method authenticated : bool

Whether the auth command ran successfully

method mail : string -> unit

Performs a MAIL FROM command. The string argument is the mail address (without < >) of the sender.

method rcpt : string -> unit

Performs a RCPT TO command. the string argument is one of the mail address the mail has to be sent to. You have to use that function for each recipient of the mail.

If the server returns a 551 error (user relocated, see RFC 2821, section 3.4), the relocated adress is silently used, and the error is not raised

method data : Netchannels.in_obj_channel -> unit

This method really send the mail. Do not issue that command without having used mail once, and at least rcpt once too

method starttls : peer_name:string option -> Netsys_crypto_types.tls_config -> unit

Sends STARTTLS, and negotiates a secure connection. This should only be done after EHLO, and only if "STARTTLS" is among the returned strings.

STARTTLS is specified in RFC 3207.

Note that it is meaningful to submit EHLO again after STARTTLS, as the server may now enable more options.

method command : string -> int * string list

Sends this command, and returns the status code and the status texts.

method tls_endpoint : Netsys_crypto_types.tls_endpoint option
