Email Quota set in DA is too large for exim

If you set a large email quota value in DA and you get and error similar to the following in your /var/log/exim/mainlog:

2010-12-11 12:43:25 1ABCDU-00087I-B0 == user@email.com R=virtual_user T=virtual_localdelivery defer (-1): quota value 1.048576e+10 is too large

Then it means your exim binary needs to be compiled with large file support.

The CLAGS option in the exim Local/Makefile should look something like

CFLAGS=-O -I/usr/local/include -D_FILE_OFFSET_BITS=64 -D_LARGEFILE_SOURCE

followed by an exim recompile, to enable large file support.
