Hello,
I am using postfix version 2.5.6.
For years I have been using the settings:
smtpd_recipient_restrictions =
permit_mynetworks,
reject_unauth_destination,
permit
smtpd_client_restrictions =
permit_sasl_authenticated,
reject_unknown_address,
reject_unknown_client,
reject_unknown_reverse_client_hostname,
check_client_access hash:/etc/postfix/access,
reject_rbl_client sbl-xbl.spamhaus.org
And that has been useful to fight some of the spam.
Now I need to connect from different places, from outside "mynetworks", from
hotels etc... and some of them can't be reverse looked up. So I setup TLS and
sasl, I get prompted for a password and it only accept the right password, so
it is basically working (and I can see the TLS connection in the log). But,
when I do that from outside mynetworks, and from an ip that cannot be reverse
looked up, the only way I can get it working is by commenting out the three
"*unknown*", otherwise I get a "450 4.7.1 Client host rejected: cannot find
your reverse hostname":
smtpd_recipient_restrictions =
permit_sasl_authenticated,
permit_mynetworks,
reject_unauth_destination,
permit
smtpd_client_restrictions =
permit_sasl_authenticated,
# reject_unknown_address,
# reject_unknown_client,
# reject_unknown_reverse_client_hostname,
check_client_access hash:/etc/postfix/access,
reject_rbl_client sbl-xbl.spamhaus.org
Is there anyway to tell postfix to accept to relay mail from an authenticated
host, even if it is on an ip that cannot be reverse looked up, but yet, reject
non-authenticated connections from hosts with this type of address.
I realise this is the wrong mailing list for this, but just in case, is there
a way to tell thunderbird to use the same password for the smtp connection as
it used for the imap connection ?
Thanks.
