The mailing list for listmasters using Sympa

[Marco Gaiarin <address@concealed>]

I've in exim configuration:

 sympa_bounce:
   debug_print = "R: sympa bounce for $local_part$domain"
   driver = redirect
   domains = LOCAL_SYMPA_DOMAINS
   local_part_suffix = -owner
   require_files = /var/lib/sympa/list_data/${local_part}
   retry_use_local_part
   data = | /usr/lib/sympa/bin/bouncequeue ${local_part}@${domain}
   pipe_transport = sympa_transport

but looking at logs, i got bounces in the form of:
