題目: [Exim] Sender address check for authenticated users
Hello,

I want to check the domain of the (envelope) sender address if a user is
authenticated. Authenticated users are allowed to relay through
our mailgate but only if they use a local sender address. I'am at a loss
at the moment. The acl_smtp_auth ACL would be a nice place for doing
this, but the AUTH command could happend before the MAIL FROM command
appears, I think. Also I can't restrict everybody to local sender
adresses, cause I want receive mail from the internet from everyone for
our local users.

At the moment I got this acl:

------------

acl_check_rcpt:

  deny    local_parts   = ^.*[@%!/|] : ^\\.


  accept  local_parts   = postmaster
          domains       = +local_domains


  require verify        = sender/callout
  require verify        = recipient


  accept  domains         = +relay_to_domains
  accept  authenticated = *


  deny    message       = relay not permitted


---------


This seems to work fine but authenticated users can use every address
they like. How can I restrict them to local addresses (domains) ??
Every hint would be appreciated.

regards
