In order to reduce the daily quantity of trash in our system, we'd like to

with dynamic IPs! Not normal communication between a customer Mail-program and
our Servers!).
Has anyone already done it? How can I do it with Exim?
You put a deny in your rcpt acl based on a dnsbl lookup,
using a dnsbl which specialises in listing dynamic and
generic IP addresses.
Additional question: how can I manage an "exception list" (for example of
Servers with dynamic IP but registered in DynDNS)?
You maintain a file of such IP addresses, and lookup in there
to avoid doing the above dnsbl test. Quite how you "manage"
the file is up to you - I'm not entirely sure what you're
asking. "vi filename" would suffice for me, but perhaps
you have too many addresses for that to be viable.
