Subject: Re: [Exim] "message filter" address
This follows from my earlier messages with the same subject.

It appears that $original_local_part expands to "message filter" when a message has
been generated by a "deliver" command in a system filter. In practice this means
that it may not be possible to use $original_local_part when using a system filter
which uses "deliver".

I can see two alternatives:

1) When using $original_local_part, make it conditional:

  ${if eq {$original_local_part}{message filter}\
    {$local_part}{$original_local_part}}


so that a legal result is always obtained.

2) Make Exim evaluate $original_local_part in this way automatically.

In the first case the documentation for $original_local_part should point out this
potential problem.

(I presume the same can be said for $parent_local_part too.)
