Postfix - Mailflood Protection?

[Holger Gebhard]

Thanks for help...

The IPBlock-Feature only partly works with postfix :-(

When I enable the feature the Files IPBlock.db and IPBlock.lock will
createt an filled with information (seems to work).
When a IP-Adress listed in IPBlock.conf goes over the limit MailScanner try
to "update" the access.db file...

Here is the Problem.

The Logs always shows something like the following:

IPBlock: Could not open access database ....

I tried the following:

1. create a empty "normal" file access.db (same error in Logfile)
2. change systemrights from "normal" access.db (same error in Logfile)
3. create a "Postfix" access.db file with postmap (same error in Logfile)
4. change systemrights from "Postfix" access.db (same error in Logfile)

Anybody knows whether Postfix use another Databaseformat than Sendmail?
Is there a chance to get this feature work with postfix?


Thank you in advance

Holger
