Hello,
I have tried to restrict users only to be able to send mail with their own
e-mail addresses.
(I am aware of difference between envelope from: and header From: but I have
to start somewhere).
after reading smtpd_sender_login_maps and reject_sender_login_mismatch I
thought I need to map all protected
I have set up:
smtpd_sender_restrictions =
reject_non_fqdn_sender,
reject_unknown_sender_domain,
reject_sender_login_mismatch
what I see in logs:
May 1 02:04:15 fantomas postfix/smtpd[31415]: warning: restriction
`reject_authenticated_sender_login_mismatch' ignored: no SASL support
May 1 02:04:15 fantomas postfix/smtpd[31415]: warning: restriction
`reject_unauthenticated_sender_login_mismatch' ignored: no SASL support
1.
- do I need to explicitly enable SASL on port 25 in order to be able to
regulate the sender addresses for users?
isn't this what reject_unauthenticated_sender_login_mismatch does?
2. reject_sender_login_mismatch
Reject the request when $smtpd_sender_login_maps specifies an owner for
the MAIL FROM address, but the client is not (SASL) logged in as that
MAIL FROM address owner; or when the client is (SASL) logged in, but the
client login name doesn't own the MAIL FROM address according to
$smtpd_sender_login_maps.
- do I understand this correctly as two alternative ways of explaining
"you can send mail from x...@example.com only if it's in
smtpd_sender_login_maps and lists your username"?
3. reject_known_sender_login_mismatch
Apply the reject_sender_login_mismatch restriction only to MAIL FROM
addresses that are known in $smtpd_sender_login_maps. This feature is
available in Postfix version 2.11 and later.
- how is this different from other reject_*sender_login_mismatch?
