Pkg exim4 users - Mar 2006 - From sendmail to exim - full name from gecos field of passwd?

Hello all,

I try to replace an old mail server running sendmail with Exim4 on Sarge.
My idea was to run a simple configuration with the same behaviour like 
the old machine and expand it, when I better understand Exim''s 
configuration.
I made an experimental installation (smarthost, local delivery in 
Maildir) and all seems to work, except that the old sendmail server uses 
the full names from the gecos field of the passwd file to accept SMTP 
mails. For example for my address it reads the first and last name and 
accepts mails to ralf.gruner@...

Can I use such a mechanism in Exim too? I have found no hint in the docs.
Or what would be a solution to replace this in a first step? My first 
idea is an alias file, but I am not sure.

Ralf

Yes. I have, however, never seen this actually done, so it looks like
you''re on your own. spec.txt chapter 11 will show you what you need
for the query. You''ll probably need a specially parametrized redirect
router, so chapter 22 is a good idea as well.

Start with the system_aliases router.

Greetings
Marc

That''s the way I would do it, too.

Create yourself a tiny perl or whatever script that creates
corresponding entries for your aliases file from aour passwd file.

Christian

I strongly assume that the indirection with a script is not necessary
and that it is directly possible to do the lookup with the user
database.

But what if there are 2 users with identical names? The
"create_aliases" script could handle this, bit what about the direct
lookup?

At least in my case this is not a problem, because the old configuration
would have not worked for identical names.
At the moment I am reading the docs to learn how the lookups work...
