I have some difficulties to understand how lookup tables are used in
postfix.

A) Single column.
You query with a parameter. If the parameter is found in the table you get a
non null value ( index value for example ). Depending of your usage you

After many tests I found that this is working :
in main.cf :

inside quotes.
By default, the Postfix address resolver does not quote the address
localpart as per RFC 822, so that
Human guru perhaps not, but programs , spammers, or others may.

email-address :: local-p...@example.com

Now the lookup table
local-p...@example.comOK
