I have virtual alias maps configured to lookup from a MySQL database:
virtual_alias_maps = mysql:/etc/postfix/mysql_virtual_alias_maps.cf

# cat mysql_virtual_alias_maps.cf
user = *******
password = ******************
hosts = ******** ********
dbname = *****
query = SELECT destination FROM aliases WHERE address='%s'

I would like to do something like:

query = SELECT destination FROM aliases WHERE address='%s' AND
somefield NOT LIKE '%value%'

But when I try, I get an error:

postfix/smtpd[12151]: fatal: db_common_parse:
/etc/postfix/mysql_virtual_alias_maps.cf: Invalid query template: SELECT
destination FROM aliases WHERE address='%s' AND destination NOT LIKE '%value%'

I have tried escaping the % signs in the LIKE clause with \, \\ and \\\ but it
doesn't make a difference.

Any ideas how I can accomplish this?

TIA,
Chris

$ man mysql_table
...
query The SQL query template used to search the database, where %s is
a substitute for the address Postfix is trying to resolve, e.g.
query = SELECT replacement FROM aliases WHERE mailbox = '%s'

This parameter supports the following '%' expansions:

%% THIS IS REPLACED BY A LITERAL '%' CHARACTER.
