Zimbra 5 install on CentOS 5 / MX Record

[MrBryce2000]

To begin, I apologize if this answer is in another post. If it is, then I didn't find it.

I am working to install Zimbra 5.02 on a 64-bit CentOS 5 Linux server. The current email setup for this organization is a simple POP3 email service to its hosting service, so I can't afford to redirect the MX record in order to setup Zimbra. Here are my questions / issues:

1. Can Zimbra be successfully installed and setup without resolving a MX record during setup?
2. If so, will it be easy for Zimbra to pick up the email traffic once the MX record is redirected?
3. Is anyone else having trouble with the SQL databases not populating during setup? Setup for Zimbra-store can not connect to the MySQL server via its socket.

I know that these are detailed questions, but any help would be greatly appreciated!

Thanks!

1. Can Zimbra be successfully installed and setup without resolving a MX record during setup?

>yes

1. If so, will it be easy for Zimbra to pick up the email traffic once the MX record is redirected?

>Depending on your TTL for you MX records. I would decrease it to abou 30 min about 2 days before the actual move.

>Can you post your zmsetup.log and install.log?

For testing purposes, I setup a second MX record and A record for my machine while testing ZCS. Then when I was ready to go online, I changed everything to the new server. If you're hosting your own DNS this is rather simple. If your ISP is hosting your DNS they may get a little perturbed if you ask them to make too many changes. Setting up the second set of records put to rest the question of no MX record while testing.

Zimbra works without MX record.

For MTA outgoing email use your providers smtp server (relayMTA for external delivery).

For incoming email, uncheck dns reverse lookup for MTA

Use fetchmail to get external pop3 mail

[Bill Brock]

Unchecking DNS checks will open up the mail server to a lot more spam. DNS checking blocks 80% of the spam trying to come into my mail server.

It's best to follow the RFC's for setting up a mail server and its DNS. Then everybody wins.

I apologize for the delay in replying (life happens).

Where is the Zimbra setup log? Is it in the /tmp or /opt/zimbra folder?

Thanks for your help!

Oddly enough it's not there. I'll see what happens on my test server.

[MrBryce2000]

Hooray! All is well with my test server (CentOS5 32bit). Zimbra 5.04GA installed perfectly! Now it's time to install it on my production server (CentOS5 64bit).

I'll report how everything turned out once I'm finished.

Thanks for your help!

I am now receiving an error during installation with ldap. Please help! LDAP is installed but not running. Are there any other packages that need to be installed? This is CentOS5 64-bit.
