In case anybody wants to use a MySql database to store aliases this is
how I managed to get my site working.
1. I added this line to the main section of
/usr/local/exim/conf/configure (where <password> is the mysql password
for the exim user)
mysql_servers = localhost/school/exim/<password>
2. I then added these lines to the Directors section after the
system_aliases director.
mysql_system_aliases:
driver = aliasfile
file_transport = address_file
pipe_transport = address_pipe
search_type = mysql
query = "select userid from user where aliasid='$local_part'"
user = exim
3. Later on I plan on using Cyrus with pwcheck_mysql to remove the need
for local accounts. As soon as I convert the mbox files to Cyrus format
I will post the rest of the Exim configuration.
