Arguments: mail-server from to message &key subject reply-to cc bcc headers login password attachments
This function requests that a SMTP server send a message. The return value of this function is undefined. If this function returns rather than signaling an error, then it has "succeeded", where "success" means the SMTP server claimed that it received the message.
mail-server specifies the mail server and also additional information. It can specify the port number, details of an SSL connection, and whether to initiate STARTTLS negotiations. The value of the argument can be a string or an IP address (to specify just a server or a server and a port number), a cons (to specify a server and a port number) or a list (to provide value for all options). See below for details.
The mail-server is contacted and asked to send a message (a string) from the email address specified by from to the email address or list of addresses specified by to. The email addresses must be of the form "foo" or "[email protected]". You can not use addresses like "Joe <[email protected]>" or "(Joe) [email protected]".
message can be a string or a stream or a mime-part-constructed
(see MIME support in
imap.htm). If it is a stream, the stream is read
until an EOF is reached, but the stream is not closed nor is the file
pointer reset.
A mail header is built and prepended to the
message before it is sent. The mail header
includes a From line and a To line
and will optionally include a Subject and
Reply-To line if those are given (as values of the
subject and reply-to keyword
arguments) in the call to send-letter. The value of the
headers keyword argument should be a string or
list of strings (or nil
). These are raw header
lines added to the header sent out with the letter.
cc and bcc can be either a string or a list of strings naming recipients. All cc's and bcc's are sent the message but the bcc's are not included in the header.
attachments, if non-nil
,
should be a list of filenames or streams (or a combination). Here is
an example using attachments:
(send-letter "localhost" "[email protected]" "user1" "Here is the image you requested" :attachments "home/user1/src/sample/OTHER/jupiter.jpg")
The text of the message should be lines separated by #\newline's. The smtp interface will automatically insert the necessary #\returns's when it transmits the message to the mail server.
The login and user keyword arguments can be used if the smtp server (specified by the mail-server argument) requires authentication.
The mail-server argument serves several functions. It can also specify a port number. And it can specify SSL and STARTTLS details. We discuss each use in turn.
The value can be a string naming a machine, or an IP address (in dotted form, as an integer for IPv4 addresses, or an IPv6 address structure).
By default, this function makes a connection to port 25 on mail-server.
If you need to connect to a port other than the default (port 25), you can specify the mail-server argument in one of the following two ways to specify the alternate port number (and, as described below, an alternate port can be specified along with SSL and STARTTLS information):
'("smtp.example.com" . 99)
and port 99 will
be used.
"smtp.example.com:99"
. Note that this form is not
suitable if the mail server is specified as an IPv6 dotted address
(because the dotted address uses colons as separators).
The most general form of the mail-server argument is a list of the form:
(server-name &key (port 25) (ssl nil) (starttls nil) ...ssl-client-keywords...)
where
nil
, the
default port is 465.
nil
, make-ssl-client-stream will be called
after establishing a connection to the smtp server. All
ssl-client-keywords are passed to make-ssl-client-stream as well.
nil
, it allows for negotiation of a
secure connection (TLSv1) if the server supports it. If the server
supports both auth and starttls, starttls will be negotiated before
attempting authentication.
nil
.
No error is signalled if both ssl
and starttls are
non-nil
. The SSL connection is established
before any starttls negotiation would begin.
