Hi all,
Just a little question.
I have configured Postfix (3.5.8 from Alpine Linux) with
"recipient_canonical_classes = envelope_recipient" &
"recipient_canonical_maps = ldap:/etc/postfix/recipient_canonical" to
rewrite envelope recepient by an OpenLDAP attribute
(preferredRFC822recipient)
I also set "local_header_rewrite_clients = static:all"
When i inspect my OpenLDAP Logs, i see that there is two nested LDAP
Search Queries coming from Postfix during the cleanup service.
The first use "%s" as value of LDAP filter.
The second use the value of preferedRFC822recipient :
5ff75ca0 conn=1002 fd=24 ACCEPT from IP=172.17.157.2:33452 (IP=0.0.0.0:389)

5ff75ca0 conn=1002 op=2 SRCH attr=preferredRFC822recipient
5ff75ca0 conn=1002 op=2 SEARCH RESULT tag=101 err=0 nentries=1 text=
I have enabled debug_peer_list, and verbose mode on smtpd, cleanup and
trivial-rewrite.
Here is the partial cleaning output corresponding of both :

I don't understand why Postix does the second LDAP Query with
(mail=bob-recipi...@guirriec.fr) filter .
Can someone explain me ?
Best regards.
