[Exim] pop before smtp and exim

It may have been more accurate for me to ask does Exim support the reading of hash files?

I.E. most of the software I have seen for pop before smtp exports it's IP lists to a hash file which you then ask the MTA
to read.


for example sendmail or postfix are compiled with hash table support so that you can go something like

smtp_relay = hash:/etc/mail/popauthd.db


they aren't just clear text files.
