just to clear things up, the post-RCPT filter is executed during the SMTP phase after each RCPT_TO transaction, before XMail sends the SMTP response back to th client. You have no message data available when the filter runs. Only client IP:PORT info, and sender return path (and, of course, current recipient address). That is how I thought it would be, which is perfect, as this would be the hook for people to have filters for outright rejection of senders and/or domains/IPs. This would enable to create user filters for *.hinet.net etc... Currently this only happens on a global base in pre-data, which is not ideal... I have also noted that the reject message from a pre-data filter only gets issued once the data gets sent, which causes some MTA's to go bonk, and ignore the failure return, only to keep resending until everything goes up in flames. I have basically firewalled out two servers that did that. One was fixed, the other is still firewalled... :) -- Best regards, Jornmailto:[EMAIL PROTECTED] - To unsubscribe from this list: send the line unsubscribe xmail in the body of a message to [EMAIL PROTECTED] For general help: send the line help in the body of a message to [EMAIL PROTECTED]

Hello Davide, How many would appreciate per-RCPT SMTP filter capabilities? This would be a very nice to have, as each user can then control their own settings etc. I was actually looking at making this a filter code decision. By default filter runs, but if user chooses to not have this filter, or have different levels for i.e. spamassasin, they can then select so accordingly. The in filter code would also allow this to be done on a per domain base. -- Best regards, Jornmailto:[EMAIL PROTECTED] - To unsubscribe from this list: send the line unsubscribe xmail in the body of a message to [EMAIL PROTECTED] For general help: send the line help in the body of a message to [EMAIL PROTECTED]

The big advantage is that we'd have control about filter execution (and not only global filters anymore).

The big advantage is that we'd have control about filter execution (and not only global filters anymore). Thanks. It should be possible, based on return code to make only the recipient fail. For example, let's say the filter returns 4 (to reject this recipient). The SMTP fail code could be 471, which means only this recipient failed. However, if the filter returns 4 + 16, then the SMTP fail code could be a 5xx code, meaning that the entire transaction fails. My own thought was to allow the filter writer to specify any SMTP error code and message (perhaps in a .REJ file or some similiar method), and simply indicate to XMail by the filter return code whether to terminate mail processing for the message, or simply dump this recipient. But I suppose it will be up to Davide how he wants to handle this...
