Exim4 wildcard addresses as Postfix does

[Chris Knadle <Chris.Knadle@coredump.us>]

Greetings.

   I'm trying to find out if it is possible to support email addresses with 
wildcards after the local_part and before the @ in the address.  I.E. 
<local*@domain>.  I've been able to do <*local@domain> using an nwildlsearch.  
The spec for Exim4 under section 9.2 for wildlsearch and nwildlsearch seem to 
specifically spell out that <local*@domain> addresses are not supported.  
Section 9.5 on partial matching in single-key lookups seems to indicate the 
same thing.

   I've also been looking into the possibility of moving over to email routing 
with LDAP lookups using the misc.schma in OpenLDAP (inetLocalMailRecipient, 
using the mailLocalAddress and mailRoutingAddress attributes), but here again 
the wildcards would seemingly be difficult.  In the case of LDAP the 
wildcards would exist in people's email addresses in the mailLocalAddress or 
'mail' attributes and I have not figured out a way to get a LDAP query that 
will match that way.

   So -- I'm looking to see if someone on this list has perhaps run into this 
and found a way to handle it.  And no, I don't want to switch to Postfix at 
this time.  :-)  Before even vaguely considering doing that I still want to 
get to the bottom of whether this is possible to do with Exim4 by some means.

   Thoughts, comments, and questions are all welcome.  Thanks in advance for 
any input.

	- Chris
