Disable spamfilter

Post by pb81 »

Hi!
If i disable the spamfilter on a user account, does this means that the server accept everything it gets?

We have a sender address that gets rejected all the time. This is probably because the DNS not having the correct SPF to allow an external mail server. But I have to accept these emails anyway.

reject: RCPT from unknown[xxx]: 450 4.7.25 Client host rejected: cannot find your hostname, [xxx]

Hello,

this error message indicates that the sending server did not configure a proper rDNS for its IP. These kind of messages will be rejected also when disabling spamfilter, as this is a technical error on the sender side (not a spam score issue).

You may disabling this check manually in /etc/postfix/main.cf, but it should be fixed on the senders side.
Viele Grüße,
Martin

Hi!
Suppose this is the right way to add a domain to the whitelist?
1. Activate check_helo_access in /etc/postfix/main.cf
2. Add domain/ip with regexp in /etc/postfix/helo_access with REJECT
