Hi,
i want to use RBL Blocking with postfix. but i've got a small i've many
users that work with mobile internet (UMTS Modem from T-Mobile) and
often they are listed and users are complaining that they cannot send
emails out.
my question is now. can i restrict rbl only to incoming mails or is
there a list that will not list mobile users form t-Mobile?
use SASL to make users authenticate to your server (SMTP authentication)
and give sasl authenticated connections precendece like this:
smtpd_client_restrictions =
permit_mynetworks,
permit_sasl_authenticated,
reject_rbl_client your.rbl.list,
[...]
see http://www.postfix.org/SASL_README.html
