I think you're on the wrong track here - I've thought about this for years and have never done it.
As Qmail-Scanner has to receive the *entire* message before it can virus/spam scan, then there's no bandwidth saving to be had by causing a SMTP error to occur. Also, as we can't get control of the error string qmail-smtpd produces without rewriting qmail-smtpd, then again, the poor end-user (let's forget about them being a spammer for a moment - they may be a false positive) simply gets a bounce saying that "an error occurred" - not exactly helpful.
Well, you're absolutely right as always. There is no bandwith saving at all, I knew that. And the message that the "hypotheticaly" innocent user will recieve is not very helpful.
No, the current system of sending a separate e-mail is still the best IMO - given the structure qmail-smtpd forces us to work under.
I think that your point of view is solid like a rock.
In the other hand, I want to 'stop' spam messages to my users, and I only stop messages with a high score (quarantine - 8 ; delete/reject - 10).
When I've started to quarantine spam messages notifying the sender I got a lot of messages in the mailserver queue, so I decided to not notify the sender.
Now I'm trying that the server in the other side will deal with the messages I reject, better they than me... Maybe I will change the source of qmail, is only a little change in the file qmail.c, just change the text of the message that qmail-smtpd returns when it receives and exit code 31 from qmail-scanner.
If qmail-smtpd actually piped the error code from qmail-queue/qmail-scanner-queue.pl back out to the SMTP client, then doing such things at the SMTP level would be best - but it doesn't....
Well, I don't understad this. Could you explain it?
Cheers
