Hello everyone,
I would like to replace / accompany the “MTA configuration-> My networks” IP list
(The list of “trusted” SMTP clients that have more privileges than “strangers”. In particular, “trusted” SMTP clients are allowed to relay mail through the MTA)
with User/Password credentials. Hence a user, that needs to sign and then relay an email, doesn’t need to be in a known and trusted IP range. Also it would gave me a better feeling if not only the IP decides if a mail is relayed or not.
Is there something build-in that I missed?
Otherwise I need to modify the mta config, right?
smtpd_sasl_auth_enable = yes
smtpd_sasl_security_options = noanonymous
smtpd_relay_restrictions = permit_sasl_authenticated
Thanks!
best wishes
David
