saslfinger - A utility to collect SMTP AUTH relevant configuration for Postfix
SYNOPSIS
saslfinger [-chs]
DESCRIPTION
saslfinger is a utility to collect SMTP AUTH relevant configuration for Postfix. Depending on how you run it, it will search for informa-
tion on server-side or client-side SMTP AUTH configuration settings in Postfix and Cyrus SASL.
OPTIONS -c If you run saslfinger with the option -c it will collect data required for client-side SMTP AUTH. Client-side SMTP AUTH is when
Postfix smtp daemon uses SMTP AUTH to authenticate itself with a remote mail server that offers SMTP AUTH.
saslfinger will try to telnet to all hosts listed in smtp_sasl_password_maps, if it may read smtp_sasl_password_maps
The telnet test verifies your host is able to reach the remote servers and shows what AUTH mechanisms they offer - in some cases
this is required to debug client-side SMTP AUTH.
Important: By default smtp_sasl_password_maps must be read-only to root, since these maps contain the usernames and passwords to
authenticate. If you run saslfinger as root access will be no problem, but saslfinger will fail if you lack the permissions to
access smtp_sasl_password_maps.
If you want to run the telnet test, but don't want to run saslfinger as root change permissions of smtp_sasl_password_maps so that
the user running saslfinger may access smtp_sasl_password_maps while you debug.
*note: You don't need to worry about saslfinger doing anything with the username or password stored next to the remote hosts in your
smtp_sasl_password_maps; saslfinger completely ignores these informations!
-h If you run saslfinger with the option -h it will print a little help message that tells you about the options you can use.
-s If you run saslfinger with the option -s it will collect data required for server-side SMTP AUTH. Server-side SMTP AUTH is when
Postfix smtpd daemon offers SMTP AUTH to mail clients.

NAME
smtp - Client-side tcl implementation of the smtp protocol
SYNOPSIS
package require Tcl
package require mime ?1.3.2?
package require smtp ?1.3.2?
::smtp::sendmessage token option...
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, con-
taining 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.
