How strange. Normally this information would just be put into a
Received: header.
Reading the HOWTO, where it speaks about "Internet->MTA1->filter->MTA2
style content filter applications", it sounds like this is just a hack
to work around the kind of problem we had with older versions of Exim --
that a message would need to pass through Exim _twice_, because the
first would pass it to an external filter, which then passed it back
into Exim for actual delivery.
That problem is fixed in Exim -- I don't really see much need for
anything like XFORWARD.
What exactly does amavisd use this for? It sounds like there should be a
better answer.
