Hi, folks,
I have iain's patch configured on my qmail server for mysql entry
query and I want to migrate to Exim, using the same sql tables.
Anyone of you know this patch (http://iain.cx/qmail/mysql/) ? I'm still
trying to figure out how it works, I have just an idea right now, that
looks just like this:
alias table:
+----------+-------+----------------+------------+
| username | alias | alias_username | alias_host |
+----------+-------+----------------+------------+
How I *think* it works:
If username = alias
seek next column
alias = x;
where it points to? x@host redirects mails to alias_username@host
Ok, looks like it's correct.
Now lets move to something a bit more complicated:
- What if... we have x as alias_username?
the patch seems to do recursive lookups
,---------------------------------------------------------------------------------------
v
^ |
username? alias --->> alias_username
|
(other)
|
| alias_host = /Maildir/? -->> Houston, we've got a real
user. |
v
|
v
|
seek_next_column ->> alias
------------------------------------------------------
I'll try to translate now this awful ascii art(?!@#$&*^@):
if username = alias seek for alias_username and check if it's a
valid login in username column, how do I know it's a real login?
alias_host appears to be /Maildir/*/*/*/* or something like that, at
least every time I see a valid login that's what a I got.
Now we have to lookup next column: alias, check if its a real
user again.. and loop lewp loopz...
else check alias_host for /Maildir/*/*/*...
I'll appreciate if someone could at least give me a hint about the
configuration files and lines for something like that (the queries I mean)
Cheers,
