How to make smtp-auth a must in sendmail

[sendmailserver]

hi all,
I am using sendmail with sasl support . I am using saslauthd mechanism as "pam" . When I enable the option "Server requires authentication" then my server checks for smtp authentication for mail sending . But I want it to be a must for sending mails .Without enabling the option nobody should be able to send mails .Is there any possibility or facility available in sendmail . Where and how to enable this option . If anybody knows kindly assist me . Your earliest answer will be very much appreciatable.

Thanks in advance.

Hi,

you must write in your access file:
Srv_Features l

After this makemap and then everyone must authentificate to send a mail.

You need these two lines in sendmail.mc:

TRUST_AUTH_MECH(`EXTERNAL DIGEST-MD5 CRAM-MD5 LOGIN PLAIN')dnl
define(`confAUTH_MECHANISMS', `EXTERNAL GSSAPI DIGEST-MD5 CRAM-MD5 LOGIN PLAIN')dnl

Don't forget to rebuild sendmail.cf and restart sendmail.
