Q0505

Question

My problem is that Exim replaces $local_part with an empty string in the system filtering. What's wrong or what did I miss?

Answer

A message may have many recipients. The system filter is run just once at the start of a delivery attempt. Consequently, it does not make sense to set $local_part. Which recipient should it be set to? However, you can access all the recipients from a system filter via the variable called $recipients.
