<strong>Answer:</strong>
 
I am not sure *why* the prior versions are still around after an upgrade. The answer I received was, we (Zimbra), shouldn't remove things during an upgrade. My impression was this was a policy decision. I'd say move those older versions out of the way into another directory. And if there are no problems, I'd say you are good to go. To be honest, I am paranoid - I never suggest remove anything on a system. :)

==SOAP API==
 
The relevant docs are in /opt/zimbra/doc. The /opt/zimbra/doc directory has most (if not all) our docs for soap.<br>
 
Regarding the URL using the admin soap stuff you need to talk to the admin server (by default port 7071).<br>
 
Example for the admin url for soap:
 
<code><pre>https://myhost:7071/service/admin/soap/</pre></code>
 
Another point of interest:  /opt/zimbra/conf/attrs/zimbra-attrs.xml

KeyTool Commands

keytool -list -keystore /opt/zimbra/mailboxd/etc/keystore -storepass `zmlocalconfig -s -m nokey mailboxd_keystore_password`

keytool -delete -alias jetty or tomcat -keystore /opt/zimbra/mailboxd/etc/keystore -storepass `zmlocalconfig -s -m nokey mailboxd_keystore_password`

Columns are MisMatch in the GAL using ZCO

1) Remove ZCO profile(s) from Outlook - Start ==> Control Panel ==> Mail

2) Once the ZCO profile is removed, go into the following directories and remove everything in the specified directories:
c:\documents and settings\<user>\local settings\application data\microsoft\outlook
&
c:\documents and settings\<user>\application data\microsoft\outlook

3) Recreate ZCO profile for Outlook - Start ==> Control Panel ==> Mail

Once you have recreated the zco profile, open Outlook, then have a look again at the GAL.

Upper Case Letters in the hostname in /etc/hosts will prevent the install from continuing

Make sure the hostname in the /etc/hosts do not contain upper case letters. Or else the install will not continue.

External Authentication with LDAP

Requires one of the following:
1) set
Set domain attribute zimbraAuthMech to ldap.
zimbraAuthLdapSearchBindPassword => bind DN of the admin user of the external directory
zimbraAuthLdapSearchBindDn => password of the admin user of the external directory
zimbraAuthLdapSearchFilter
zimbraAuthLdapSearchBase (optional, if not set "" will be used).
Three things are needed for auth to the external LDAP server:
- URL of the LDAP server: zimbraAuthLdapURL
- password entered by user
- the bind DN for the user, this can be setup using one of the following 3 ways. (A) is preferred over (B) because (C) does an extra LDAP search.

(A) zimbraAuthLdapBindDn
This is the bind DN template

(B) zimbraAuthLdapSearchFilter
If set, then zimbraAuthLdapSearchBindPassword, zimbraAuthLdapSearchBindDn, and zimbraAuthLdapSearchBase also need to be set.
Server uses the four attrs to get the bind DN for the user.
Server first does a LDAP search using the zimbraAuthLdapSearchBindDn/zimbraAuthLdapSearchBindPassword credential by zimbraAuthLdapSearchFilter under zimbraAuthLdapSearchBase. The search would return the bind DN for the user, if found.
example for zimbraAuthLdapSearchFilter: (&(mail=%u@%d)(objectclass=person)) (whatever object class they are using)

(C) Account attribute zimbraAuthLdapExternalDn
Unlike (A) and (B), which are domain settings, this is an account level setting. This overrides the bind template and/or search setting, and directly contains the DN for the user in the external ldap server.

OR

2) set
Set domain attribute zimbraAuthMech to ldap.
zimbraAuthLdapBindDn to the template filter for the user in the external directory.
For example, if the user exists at uid=jsmith,cn=users,dc=zimbra,dc=com , set zimbraAuthLdapBindDn on the domain to: uid=%u,cn=users,dc=zimbra,dc=com
Another example uid=%u,ou=people,%D (whatever LDAP DIT structure they are using)

zimbraAuthLdapBindDn and zimbraAuthLdapSearchFilter can contain expansion variables that are to be substituted by components in the account name:
%n = username with @ (or without, if no @ was specified)
%u = username with @ removed
%d = domain as foo.com
%D = domain as dc=foo,dc=com

e.g. for user rking@zimbra.com
%n => rking@zimbra.com
%u => rking
%d => zimbra.com
%D => dc=zimbra,dc=com

example for zimbraAuthLdapBindDn: uid=%u,ou=people,%D (whatever LDAP DIT structure they are using)

Mix external authentication users with local users

Lets say, you are using external authentication; however, you would like to create a few users locally on the Zimbra system without provisioning users on the external authentication system (openldap, AD etc etc).

This should be possible with setting the following domain attribute.

zmprov md yourdomain.com zimbraAuthFallbackToLocal TRUE

Sending Attachments

If you are having trouble sending attachments, and you *think* you've set the zimbraFileUploadMaxSize & zimbraMtaMaxMessageSize, correctly, then find out how much larger a MIME version of a file will be after base-64 encode.

If you want to find out just how much larger a MIME version of a given file will be, run the file through UUDeview (windows app) - try 'base 64' in the encode settings. Won't wreck your current file, it creates a converted duplicate. This should give you an idea of what values to use if you don't want to use an arbitrary value. http://www.miken.com/uud/

Removing older version inside /opt/zimbra

Question:
Can I delete older versions of software that is in the /opt/zimbra directory? I have older version of amavisd, clamav, cyrus-sasl, etc.

Answer: I am not sure *why* the prior versions are still around after an upgrade. The answer I received was, we (Zimbra), shouldn't remove things during an upgrade. My impression was this was a policy decision. I'd say move those older versions out of the way into another directory. And if there are no problems, I'd say you are good to go. To be honest, I am paranoid - I never suggest remove anything on a system. :)

Hardware Support

Question
In the server, one of the hard disks is showing a red light. It is Raid 5 configured. Not sure where to look.

Answer
Zimbra Support can't help very much here. We support the Zimbra software, not the server hardware or the OS RAID infrastructure. If it's a standard Linux RAID, you can remove it from the RAID group with mdadm, replace the device, and add a new device to replace it. If it's a separate array or something, you'll have to go to the manufacturer instructions to find the procedure for replacing the device. You'll probably find more information with a web search than you can get from us on this topic.

Zimbra Mobile and BIS

Customers using utilizing AT&T and Verizon for their Blackberry Internet Services (BIS) will need to make sure port 993 is accessible. Apparently, BIS services will authenticate using port 993. I had a case where the admin was using AT&T to setup an account; however, he was getting the "connection timed out" message, or "cannot authenticate" from the AT&T app. On a hunch I suggested opening port 993 through his firewall (because it wasn't accessible to the outside world) . After that was done, AT&T was able to authenticate.

Distribution Lists and Duplicates

The scenario is that you are a member of a distribution list, and also was CC'd separately, and you have noticed you have received two messages instead of one; send to: you@someZimbraList.com, you@domain.com.

Have a look at the following global setting:

zmprov gacf | grep zimbraMessageIdDedupeCacheSize

If this setting was set to zero, that would probably explain the duplicates you may see.

If you need to suppress the duplicates, run this command:

zmprov mcf zimbraMessageIdDedupeCacheSize 3000
**3000 is the default**

This would require to restart Jetty services.

zmmailboxdctl restart
**be advised this would be a slight disruption of services. you may need to restart jetty during low-peak times, or after business hours.**
