Hi,
I'm an Austrian Linux user living and working in South France.
I've just setup a basic - and working - mail server on Debian Squeeze,
using Postfix and Dovecot.
I've installed policyd-weight for basic spam filtering. Since the
defaults are quite restrictive, I thought I'd try with a bit of
additional whitelisting.
I tried a first rejected mail, read the logs and edited
/etc/postfix/whitelist accordingly:
# /etc/postfix/whitelist
smtp-152-tuesday.nerim.net OK
194.79.134.152 OK
And then:
# postmap whitelist
The relevant stanza in main.cf looks like this:
smtpd_recipient_restrictions = permit_mynetworks,
permit_sasl_authenticated,
reject_unauth_destination,
check_client_access hash:/etc/postfix/whitelist,
check_policy_service inet:127.0.0.1:12525
smtpd_helo_required = yes
This first problem resolved fine, and the initially refused mail can go
through now.
But I'm facing another problem with a message from Hotmail, which gets
rejected over and over.
Here's what the log looks like:
# grep policyd /var/log/mail.log
...

Now I tried to add this to /etc/postfix/whitelist:
# /etc/postfix/whitelist
smtp-152-tuesday.nerim.net OK
194.79.134.152 OK
hotmail.com OK
... but messages from Hotmail still get rejected.
Which leaves me clueless. Any suggestions?
Cheers from South France,
