With Postfix +3.0 and later, the old AUXLIBS variable still supports building a statically- +loaded SQLite database client, but only the new AUXLIBS_SQLITE variable +supports building a dynamically-loaded or statically-loaded SQLite database +client. + + Failure to use the AUXLIBS_SQLITE variable will defeat the purpose of + dynamic database client loading. Every Postfix executable file will have + SQLITE database library dependencies. And that was exactly what dynamic + database client loading was meant to avoid. + +Then, just run 'make'. + +UUssiinngg SSQQLLiittee ttaabblleess + +Once Postfix is built with sqlite support, you can specify a map type in +main.cf like this: + + alias_maps = sqlite:/etc/postfix/sqlite-aliases.cf + +The file /etc/postfix/sqlite-aliases.cf specifies lots of information telling +Postfix how to reference the sqlite database.
