postfix is configured to transport mail to maildrop (by either a postfix
transports file or a mysql lookup).

It's a nightmare to implement quotas with some of the mailboxes at this
stage (there are a few larger ones than just that user).

For the present (holidays and so forth) I'm content with the backlogged
mail delivery problem resolved for now.


Thanks for the help.

or, someone form FreeBSD to help you with installing libtool and courier
packages the FreeBSD way (ports), not manually from sources.

Dear Sam:

Thank you for replying. I tried to keep my original message brief, and must  
have tried too hard. I also had thought that I should use a preconfigured  
installation. I originally installed the FreeBSD libtool package, then  
installed the port, and finally installed from source as a last resort. The  
courier-auth configure script never could find any of the three installed  
ltdl.h files. All ltdl.h files are still installed, and are identical. I  
tried copying the original ltdl.h file from /user/local/include to  
/usr/include, which does include other header files, but the courier-authlib  
configure script still fails with the same error: Unable to find ltdl.h.


Randomly copying files around is unlikely to have productive results.

You mentioned that I could “pass CPPFLAGS to configure.” Unless you have a  
better suggestion about what to try next, please point me toward any  
documentation available about how to appropriately pass CPPFLAGS to the  
configure script.


./configure "CPPFLAGS=-I"

You do not appear to have a tecnical background. This isn't very  
complicated, but some technical knowledge is needed to build software from  
source. Perhaps you should ask someone else in your organization for  
assistance, here.
