Yesterday night we try lowering all defence and we leave in tcp.smtp only : 127.:allow,RELAYCLIENT="" :allow Regarding RBL we think Is all OK because the mail pass the rbl check and chkuser see them and accept them. _____ Da: Jake Vickers [mailto:j...@qmailtoaster.com] Inviato: venerdì 17 aprile 2009 12.42 A: qmailtoaster-list@qmailtoaster.com Oggetto: Re: [qmailtoaster] SMTP Reject mail random Del Rosso Massimo wrote: Hi to all, It s one day and one night we are working o a server that seem to reject mail random. In detail we are an ISP and we notice that some mail of customer are not delivered to Maildir. The problem is that if the message reach the queue all will gone but a lot of good mail do not. We stop simscan and with it calm and SA. We delete the rule of badmailto and badmailfrom. We have only rbl and chkuser. Any Idea ? We need more details than that. What shows in the logs? What does your tcp.smtp file look like? Are they being blocked by your RBL?
