Hello,
You can use NarpaxPOP (http://www.narpax.com.br/projects/narpaxpop.jsp)
to insert the IP/user/time on a database (Mysql or Postgresql) so Exim
can perform
checks on the IP, the time and the From (from who has authenticade
though pop3).
NarpaxPOP is a high-performance POP3 wich fully implements RFC 1939
and uses MySQL or PostgreSQL for authentication and supports only
Maildir.
Regards,
Lists
