I received the following logged errors
postfix/smtpd[126515]: connect from mx1.testo.tel[52.39.45.118]
postfix/proxymap[126516]: warning:

Can i trust postfix protects against SQL injections? I can't see what
the query ended up looking like but the query error makes me concerned.
I assumed if they can't escape the string quotes there shouldn't be a
query error. Or is this error harmless to security and nothing more than
just a failed lookup?
