Re: [Exim] Newbie question - Roaming Users, SMTP Auth and My…

Here is a naïve and completely untested solution which will require
tweaking.. (you've got 1œ days left :)

Early in your RCPT ACL say "accept authenticated = *"

Your authenticators should look a little like this:

cram_md5:
driver = cram_md5
public_name = CRAM-MD5
server_secret = ${lookup mysql{select password from bigtable where username='${quote_mysql{$1}}'}{$value}fail}
server_set_id = $1

(I may have my syntax wrong.)
