Hello, licenses for commercial virus scans are expensive, so in our mailserver setup we cannot not provide a virus scan for everyone, but just for customers paying for this extension.
In the acl_check_data we do a conditional virus scan: If one of the recipients given in this smtp-session has paid for the virus scan and a virus is found, then the mail is refused directly after the DATA-command. But there is a second case that may occur: Someone sends a virus to a mailforwarder on our server (e.g. [EMAIL PROTECTED]) that forwards to a mailbox (e.g. [EMAIL PROTECTED]) that requires a virus scan. In that case the virus wouldn't have been refused by the acl_check_data, because [EMAIL PROTECTED] hasn't paid for virus scan so our mailserver would accept the email. But the virus still shall not reach the mailbox of [EMAIL PROTECTED] and I don't know how to configure that in exim. As forwarders can have more than one recipient and these recipients might be handled internally or by external mailservers, it is impossible to check if the recipient of a forwarder requires a virus scan. Forwarders could also have multiple forwarders until they reach the mailbox (e.g. [EMAIL PROTECTED] -> [EMAIL PROTECTED] -> [EMAIL PROTECTED]). My goal is that no virus reaches a mailbox and that the sender of the mail gets a usual bounce message (as it would get by the refusal after the DATA-command). But since the mail has already been accepted by the mailserver at this point I don't know how to prevent the virus from reaching the mailbox and how to generate a bounce message then.
