Hi Everyone, I thought I'd try asking here before joining the postfix mail list since I'm running postfix on a CentOS 7 box. I want to look up accounts via LDAP (an IPA server also on CentOS 7). I created an "ldap_aliases" file and successfully tested it with the postmap command: I can get the email address for an arbitrary user. But, when I add the very same file to main.cf, I don't see anything in the normal or debug logs for postfix that would indicate postfix is even trying to do a ldap lookup.
Can you please provide the "postmap -q ranbir@xxxxxxxxxxxxxxxxxx ldap:/etc/postfix/ldap_aliases" call output? I guess "ranbir@xxxxxxxxxxxxxxxxxx" (from log below) is the alias and not the result of the alias.
Here are the relevant configs: # Virtual domains virtual_mailbox_base = /var/spool/mail virtual_mailbox_maps = hash:/etc/postfix/virtual_mailbox virtual_mailbox_domains = thesandhufamily.ca virtual_alias_maps = hash:/etc/postfix/virtual, hash:/etc/mailman/virtual-mailman, ldap:/etc/postfix/ldap_aliases
Plain main.cf excerpts are not useful to debug a failure situation. At least run yourself "postconf -n" to make sure that what you intend to configure is really set for Postfix. In case this thread goes on, paste it here.
What cannot be concluded from your config is how you achieve LMTP delivery. virtual_transport being used?
NB: I believe I don't need to use ldap for virtual_mailbox_maps and virtual_mailbox_domains, but I could be wrong.
Correct, you can mix different map types.
All I get is errors like this: Dec 14 09:53:35 mailman01 postfix/lmtp[31011]: A968CC2516D: to=<ranbir@xxxxxxxxxxxxxxxxxx>, relay=10.200.5.24[10.200.5.24]:24, delay=1.1, delays=0.78/0/0.01/0.27, dsn=5.1.1, status=bounced (host 10.200.5.24[10.200.5.24] said: 550 5.1.1 <ranbir@xxxxxxxxxxxxxxxxxx> User doesn't exist: ranbir@xxxxxxxxxxxxxxxxxx (in reply to RCPT TO command))
Not your Postfix refuses the mail but the host on IP address 10.200.5.24 does that on the LMTP listener. That system, the mail storage server does not know the mailbox "ranbir@xxxxxxxxxxxxxxxxxx". So, should "ranbir@xxxxxxxxxxxxxxxxxx" exist there or should that address have been translated by the virtual_alias_maps?
Am I supposed to enable something else in postfix to make ldap work? What I've read about this seems to indicate I'm doing it correctly.
If the manual postmap lookup succeeds, then the map type is supported. You can query the possible map types with "postconf -m". Postfix on CentOS 7 is compiled agains LDAP, thus the ldap map type is supported.
