Since postfix-2.9. 20100617, sqlite3 support feature was added. Now, in postfix-2.9.20110501 rpm source, i’ve included sqlite3 feature after some tweaking on Simon J. Mudd’s postfix source. Adding sqlite3 support howto can be read officially from here:
Before getting any further, i must warn you that i’m not test sqlite feature yet, since i don’t use sqlite as sql storage backend. it was compiled againts sqlite library in my system. but not tested.
rpm source can be obtain here:postfix-2.9.20110501.src.rpm (509)
After download the source install the source
