Salve!
Mandei uma d�vida um tempo atr�s e n�o obtive resposta. Serei o mais claro
poss�vel.
Quero que meus usu�rios de e-mail se autentiquem para envio de correio.
Tenho o sendmail configurado com smtp-auth e isto est� funcionando. O
problema � que o sendmail n�o est� exigindo autentica��o.
Assim, se um usu�rio configura o seu MUA sem autentica��o, meu servidor
envia o e-mail.
Observando no "Sendmail Installation and Operation Guide", observei que
tenho uma forma de requerer autentica��o. Vejam o trecho extra�do de l�,
abaixo.
A quest�o �: qual � a vari�vel no MC ou no sendmail.cf para colocar o tal
'l'?
N�o adianta oferecer autentica��o e n�o requer�-la, certo?
Obrigado!
5.1.4.14. srv_features
The srv_features ruleset is called with the connecting client's host
name when a client connects to sendmail. This rule set should return $#
followed by a list of options (single characters delimited by white
space). If the return value starts w ith anything else it is silently
ignored. Generally upper case characters turn off a feature while lower
case characters turn it on. Option `S' causes the server not to offer
STARTTLS, which is useful to interact with MTAs/MUAs that have broken
START TLS implementations by simply not offering it. `V' turns off the
request for a client certificate during the TLS handshake. Options `A' and
`P' suppress SMTP AUTH and PIPELINING, respectively. `c' is the equivalent
to AuthOptions=p, i.e., it doesn 't permit mechanisms susceptible to
simple passive attack (e.g., PLAIN, LOGIN), unless a security layer is
active. Option `l' requires SMTP AUTH for a connection. Options 'B', 'D',
'E', and 'X' suppress SMTP VERB, DSN, ETRN, and EXPN, respectively.
A Do not offer AUTH
a Offer AUTH (default)
C Do not require security layer for
plaintext AUTH (default)
c Require security layer for plaintext AUTH
L Do not require AUTH (default)
l Require AUTH
