*) Please make sure your Debian upgrade was successfully completed: http://www.iredmail.org/forum/post25079.html#p25079
*) Show us "postconf -n" please. But i think it's related to Dovecot config because Postfix uses Dovecot as SASL auth server.

Zhang,

Could you please reply?

Thanks.

dovecot -n follows. Thanks for your help.

When I send an email from gmail.com to mydomain, dovecot.log says:

Yes, they are correct.

Could you please tell me where to change that ?

I fixed dovecot-ldap error. Now dovecot.log shows the following error:
Oct 20 15:14:51 auth: Fatal: LDAP: No uris or hosts set
Oct 20 15:14:51 master: Error: service(auth): command startup failed, throttling for 60 secs

I checked the old and the new dovecot-ldap.conf file. The 'hosts' line is commented in both. What I should add there ?

Yes it was working perfectly before upgrading. But don't know which configs it was using.

I have the snapshot image of the old system (before upgrading). I have checked the entire system for dovecot-ldap.conf.

There is one in /etc/dovecot/dovecot-ldap.conf and another one in /usr/share/dovecot/dovecot-ldap.conf

Everyline inside both files are commented except the line 'base='.

I also checked the new system after upgrading. These files exist, but everything inside is commented except 'base='.

Also these files look totally different from the sample file in iRedmail package: /root/iRedMail-0.8.4/samples/dovecot/dovecot-ldap.conf. This particular file contains the following:

hosts           = PH_LDAP_SERVER_HOST:PH_LDAP_SERVER_PORT
ldap_version    = PH_LDAP_BIND_VERSION
auth_bind       = yes
dn              = PH_LDAP_BINDDN
dnpass          = PH_LDAP_BINDPW
base            = PH_LDAP_BASEDN
scope           = subtree
deref           = never

But all these parameters are commented in /etc/dovecot/dovecot-ldap.conf and  /usr/share/dovecot/dovecot-ldap.conf

I have tried using the file /root/iRedMail-0.8.4/samples/dovecot/dovecot-ldap.conf and it says that:

Error in configuration file /etc/dovecot/dovecot-ldap.conf line 2: Invalid number: PH_LDAP_BIND_VERSION
LDAP: ldap_init() failed with hosts: PH_LDAP_SERVER_HOST:PH_LDAP_SERVER_PORT

By the way, I remember during the first time installation of iRedmail in my server, I selected MySQL instead of OpenLDAP. (In the screen "Choose your preferred backend used to store mail accounts").  So why configuring LDAP now ?

Zhang,

I got the new dovecot.conf from this url.

http://www.iredmail.org/forum/topic4493 … tos-5.html
https://bitbucket.org/zhb/iredmail/raw/ … ecot2.conf

I have made changes as you specified in the url and then upgraded Dovecot. I chose the dovecot2.conf because apt-get dist-upgrade was complaining about the old dovecot.conf settings. (pop3s, imaps, managesieve etc). Thus the ldap problems started coming.

Now what do you suggest to fix this ? I can revert the dovecot.conf file, but need to manually update it to the latest syntax and settings.

Thanks.

Do you have package 'dovecot-mysql' installed?

Zhang,

Could you please reply ?

thanks.
