Hi!
I think the transport_filter option (which version has that option
been first implemented?) could be suitable for implementing a virus
scanner. However, such a filter must have an opportunity to suppress
message delivery at all.
May I suggest that exim takes a look at the transport_filter's return
value?
0 = continue delivery as plannd
1 = discard message
2 = bounce message
Possibly the transport_filter should have some control over the
subsequent delivery process, but that is beyond my scope.
For the virus scanner project, does the transport_filter have a means
to change the destination address? It would be fine to re-route
infected messages to a special address or even /dev/null.
Is it possibly better to do this in a pipe transport? This has several
disadvantages, including the need to re-submit the mail for final
delivery which causes a second set of log entries to be made for this
message.
Any comments on this?
Greetings
Marc
