I use the code which Jonas posted at frukt.org against MySQL, with a few
minor mods. Yes, it is complex, but that's life. If you don't understand
what the code is doing and why, why would you be happy to include it in your
filter, and potentially lose mail?
One issue which I've seen is on low-usage systems (such as my home server),
the MySQL connection times out, meaning that the slaves crash when the next
message comes in to them. I tried lots of things to stop this happening,
including cached connections and checking the connection status and
reconnecting if it wasn't live, but basically I couldn't avoid the slave
dying. However, this is no real problem - the multiplexor starts a new one,
the sender tries again, and all is well, since this only happens on very
lightly loaded systems, and I have 2 slaves in total at quiet periods.
