[SOLVED] Sendmail Relay Question (address check against Zimbra)

[Robert Mortimer]

I have set up a Sendmail SMTP machine as our fail-over mail server. When our ADSL is down it now collects email for our domain and delivers it forward when the ADSL is up again.

I can replicate the Zimbra ldap to the sendmail machine. Anyone got a good HOW to for checking valid addresses against LDAP on a sendmail relay?

SendMail and the LDAP Protocol

[Robert Mortimer]

Mere mortals edit the /etc/mail/sendmail.mc and let the macro rebuild sendmail.cf. Editing sendmail.cf is "Hard Core".

At the moment I am looking at FEATURE(`ldap_routing')

The feature can be used to route mail on an individual basis based on LDAP lookup. The example lookup is as follows.

ldap -1 -T<TMPF> -v mailRoutingAddress
-k (&(objectClass=inetLocalMailRecipient)
(mailLocalAddress=%0))

This returns the destination mail server based on a match in mailLocalAddress to return mailRoutingAddress . Obviously this will have to be amended to match the Zimbra shema:-

Maybe

ldap -1 -T<TMPF> -v zimbraMailHost
-k (&(objectClass=organizationalPerson)
(mail=%0))

Will keep list informed of progeress

I'm about there but I need to get an LDAP V2 bind to Zimbra in order to allow sendmail to connect. I have tried adding "allow bind_v2" to slapd.conf in /opt/zimbra/openldap/etc/openldap but no joy so far. Any ideas?

How did you restart LDAP ? Just ensure that your modification is persistent across restarts as most of the configuration gets re-written.

[Robert Mortimer]

Re-written from where?
Where is the template file?
is there a zmconfig option to add the parameter?

[uxbod]

try

zmlocalconfig | grep -i ldap
zmlocalconfig | grep -i slapd

it may be that it has not been over-written so just check your slapd.conf after a restart to ensure your mods are still present.

[Robert Mortimer]

Nothing of use in

zmlocalconfig | grep -i ldap
zmlocalconfig | grep -i slapd

It upsets my users when I re-start the server during the day so I will try a restart tonight.

Is there an easy way to just re-start the LDAP server

Zimbra CLI Command List - Zimbra :: Wiki

I have "allow bind_v2" in /opt/zimbra/openldap/etc/openldap/slapd.conf
After a re-start of the LDAP it is still there but I can not do a LDAP version 2 bind.
