I'm quite new at Exim, and I'm having a bit of trouble getting SMTP
authentication to work.
Here are the relevant bits of exim.conf:
host_auth_accept_relay = *
plain:
driver = plaintext
public_name = PLAIN
server_condition = "${if
crypteq{$2}{${extract{1}{:}{${lookup{$1}lsearch{/etc/exim/passwd}{$value}{*:*}}}}}{1}{0}}"
server_set_id = $1
I want it to work with most clients. I haven't done SMTP authentication
before so I don't really know which are the most common mechanisms..
My /etc/exim/passwd contains but a single line:
sha:foo
I'm not sure how to interpret that server_condition (as I said, I'm
quite new to exim). I can hardly even break it into parts. This is my
guess:
${lookup{$1}lsearch{/etc/exim/passwd}{$value}{*:*}}
lsearch can look through text files. lookup calls lsearch and tells it
to search for a key $1. My guess is that $1 expands to the username
supplied in the SMTP AUTH string by the client, correct?
If so, the password "foo" is returned to extract. Extract returns the
first field seperated by ":"'s, which in this case is "foo", right?
Now this is crypteq'ed to $2, which I'm guessing is the password from
SMTP AUTH. So far so good.. What is /etc/exim/passwd supposed to look
like to make this work? I can't seem to figure it out.
