[exim] Exim big plans

Good day all,

I have a couple of ideas for my own home built exim mail cluster, I wonder
if the people of the list can't comment on the ideas:

1.) Exim will save all mails to a SNAP server over the net using NFS.
2.) Exim is going to use a SQL server for authetication.
3.) Qpopper works with the SQL server for auth and will be hosted on a
different server. (problem is no imap support :(


Thanks,
Michael
