smtp(n) 1.3.3 "smtp client"

NAME

smtp - Client-side tcl implementation of the smtp protocol

SYNOPSIS

package require Tcl
package require mime ?1.3.3?
package require smtp ?1.3.3?

DESCRIPTION

The smtp library package provides the client side of the smtp protocol.

::smtp::sendmessage token option...

This command sends the MIME part (see package mime) represented by token to an SMTP server. options is a list of options and their associated values. The recognized options are:

-servers

A list of SMTP servers. The default is localhost.

-ports

A list of SMTP ports. The default is 25.

-queue

Indicates that the SMTP server should be asked to queue the message for later processing. A boolean value.

-atleastone

Indicates that the SMTP server must find at least one recipient acceptable for the message to be sent. A boolean value.

-originator

A string containing an 822-style address specification. If present the header isn't examined for an originator address.

-recipients

A string containing one or more 822-style address specifications. If present the header isn't examined for recipient addresses). If the string contains more than one address they will be separated by commas.

-header

A list of keywords and their values (may occur zero or more times).

If the -originator option is not present, the originator address is taken from From (or Resent-From); similarly, if the -recipients option is not present, recipient addresses are taken from To, cc, and Bcc (or Resent-To, and so on). Note that the header key/values supplied by the -header option (not those present in the MIME part) are consulted. Regardless, header key/values are added to the outgoing message as necessary to ensure that a valid 822-style message is sent.

The command returns a list indicating which recipients were unacceptable to the SMTP server. Each element of the list is another list, containing the address, an SMTP error code, and a textual diagnostic. Depending on the -atleastone option and the intended recipients, a non-empty list may still indicate that the message was accepted by the server.

EXAMPLE

proc send_simple_message {recipient email_server subject body} {
    package require smtp
    package require mime

    set token [mime::initialize -canonical text/plain \\
    -string $body]
    mime::setheader $token Subject $subject
    smtp::sendmessage $token \\
    -recipients $recipient -servers $email_server
    mime::finalize $token
}

send_simple_message someone@somewhere.com localhost \\
    "This is the subject." "This is the message."
