[exim] message sizes per host

Hello,

I'm struggling to get messages sizes at helo/ehlo-time working in a way
that some hosts may use larger sizes.

Following ideas I have followed till now:
- message_size_limit = ${if eq {$sender_host_address}{...}{..}{..}}
This works well with one or two hosts, but not with a bunch of it.

- message_size_limit = ${if domain_on_list {sender_host_address}{+large_messages}...}
That's on the wishlist.

- in connect_acl:
  warn
    hosts = ....
    set acl_c0 = big
  But connect ACL is executed after setting of the sizes, so doesn't
  work.

- Another idea would be to have something like message_size_limit_large
with a list of hosts that can use the large one (like the
connections_reserved etc).


So, what's the best way to continue here?



Cheers,
Andi
