Sorry this was wrong. Disabling DNS-based tests changed nothing. CPU was used by Xwall running on the same server. Xwall is acceppting messages on both servers on port 25 does external recipient verification and from today on (after I've noticed the problems in subject!) it does also block durring SMTP-Envelope messages comming from hosts listed in XBL-SBL. Without this enabled the proc folder would already be filled up with more then 30k messages. Both servers process usually >100k messages each day and they have this done with declude v1.81 until 2005-12-31 and afterwards with declude v.3 Only today it seems they wouldn't work anymore with full speed... :-/ Markus --- [This E-mail was scanned for viruses by Declude EVA www.declude.com] --- This E-mail came from the Declude.JunkMail mailing list.
