Ispconfig and spam

[edge]

I've been using it that way (with the #), for a long time, and did not have a problem with it.

i use this option

smtpd_recipient_restrictions =
reject_invalid_hostname,
reject_unknown_recipient_domain,
reject_unauth_pipelining,
permit_mynetworks,
permit_sasl_authenticated,
reject_unauth_destination,
reject_rbl_client dsn.rfc-ignorant.org,
reject_rbl_client dul.dnsbl.sorbs.net,
reject_rbl_client list.dsbl.org,
reject_rbl_client sbl-xbl.spamhaus.org,
reject_rbl_client bl.spamcop.net,
reject_rbl_client cbl.abuseat.org,
permit

but if someone email from @geldermalsen.rabobank.nl
then i get no mail
what can i do this adres is not in the spam lists!

That's because this domain is not valid:

:~$ dig geldermalsen.rabobank.nl

; <<>> DiG 9.3.2 <<>> geldermalsen.rabobank.nl

See? No ANSWER section. One of you reject statements is triggered by this. Don't know for sure, but I'd suspect reject_unknown_recipient_domain, or dsn.rfc-ignorant.org. Or better, ask your contact at the bank to use a valid from/return address.

Personally, i do not have good experience with the blacklists as mentioned within /etc/postfix/main.cf. It causes to much problems for clients.

Right now i am using Postgrey, an easy to install software package for the Postfix MTA. I have good experience with it and it works very well on an ISPConfig server.

Here you can read how to setup Postgrey for Postfix:
