Hello,
I've configured check_sasl_access to be a sql map, like so:
proxy:mysql:/etc/postfix/checks/check_sasl_access.sql
and that check_sasl_access.sql file has the regular database DBI bits,
and then the following query:
query = SELECT CONCAT("PREPEND X-User-ID: ",
encrypt_user_id(mailboxes.user_id)) FROM mailboxes WHERE mailboxes.address =
'%s';
this encrypt_user_id(mailboxes.user_id) is a stored procedure in the
database which allows me to create a hash of the sasl authenticated
user_id, with a secret, and returns a header value that helps us
identify users (esp. for spamming) from headers, without revealing
information to others.
This all works fine. The only problem is, if I CC or BCC someone, I get
one of these X-User-ID: headers for each additional address that is
included. It is the header for the sasl authenticated user, as expected,
repeated multiple times, once for each address included.
How can I make this only occur once in the header and now repeat it for
every address CC/BCC'd?
thanks!
micah
