The problem is with dspam-3.10.2, when retraining and attempting to redeliver a false-positive from quarantine. Retrain appears to succeed, but redelivery fails, with the DSpam web interface reporting only that an unknown fatal error occurred. Postfix logs the following: ==> mail.log <== Oct 3 14:48:23 epsilon3 postfix/smtpd[7639]: connect from localhost[127.0.0.1] Oct 3 14:48:23 epsilon3 dspam[7638]: Got error 500 in response to RCPT TO: 500 5.5.2 Error: bad UTF-8 syntax^M Oct 3 14:48:23 epsilon3 postfix/smtpd[7639]: disconnect from localhost[127.0.0.1] helo=1 mail=1 quit=1 commands=3 Failure consumes the message, so a limited supply of false positives badly limits ability to test and troubleshoot the problem. -- Phil Stracchino Babylon Communications ph...@caerllewys.net p...@co.ordinate.org Landline: 603.293.8485
