since a fews days, I'm getting tons of spam to our postmaster@mydomain.net address.
Antispam is configured to use RBLs and RDNS checks and is working fine for all other addresses, but not for the postmaster address.
Here is the header of most recent spam mail:
Received: from [190.232.106.214] (port=23186) by mailoutkae1.dbrs.de with

The IP 190.232.106.214 is listed in CBL RBL, which we are using, but it did not block => RBL check seems not to work for postmaster
The IP 190.232.106.214 has no RDNS set, so the mail should have been bounced with "Rejected: RDNS/HELO (RDNS missing)" => RDNS check seem not to work for postmaster
Any Ideas?
