saslfinger - A utility to collect SMTP AUTH relevant configuration for Postfix
saslfinger is a utility to collect SMTP AUTH relevant configuration for Postfix. Depending on how you run it, it will search for information on server-side or client-side SMTP AUTH configuration settings in Postfix and Cyrus SASL.
-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.
