Hello all. I have my exim install setup such that I have a seperate domain file for each domain, where I store all my aliases.

What I want to know how to do is get it so that a specific e-mail address bounces. Here is my config (relavent)

##########################
domain_aliases:
  debug_print   = "domain_aliases for $local_part@$domain"
  driver        = aliasfile
  optional      = yes
  file          = /etc/exim/domain_aliases/$domain
  search_type   = lsearch*
##########################

Example alias file
##########################
/etc/exim/domain_aliases/here.com

*:              me@???
##########################

How do I add an entry so that bounce@??? bounces back the user?

Thanks,

Darren
