<center><u>'''Sandhar Technologies Mail Server Architecture'''</u></center>

Cluster : 2 Nodes (node1.sandhar.in, node2.sandhar.in )

Commonly named as node.sandhar.in and working with name mail.sandhar.in

Archiving : 1 Server (archive.sandhar.in)

Node2.sandhar.in

172.17.16.98Archive.sandhar.in

172.17.16.99 Node1.sandhar.in

172.17.16.97Node.sandhar.in

172.17.16.22

Only MD's Mails were forwared to the remote MS exchange server for the mobile syncronization facility, It's done by adding an additional domain in the server name msexc.sandhar.in and create the user and then provide the remote mail box information in mail transport.

You have the option of notifying Zimbra of your installation.

This helps us to track the uptake of the Zimbra Collaboration Server.

The only information that will be transmitted is:

The VERSION of zcs installed (8.5.1_GA_3056_CentOS6_64)

The ADMIN EMAIL ADDRESS created (admin@sandhar.in)

Notify Zimbra of your installation? [Yes]

'''2) Avoiding conflicts: what are the default port configurations when Zimbra is installed?'''

Some Important open port there is may more ports zimbra use internally, but below wer important and need to take care.

587 Subbmission smtp port143 Imap port

465 secure smtp port

22 ssh port

25 smtp port

443 secure http port

7071 zimbra admin port

993 secure imap

995 secure pop

389 ldap port

'''3) How do I make sure that DNS is configured correctly?'''

1<sup>st</sup> login to the server and check with below commands

<nowiki># host sandhar.in</nowiki>

<nowiki># host -t mx sandhar.in </nowiki>

or we can test with dig command

<nowiki>#dig sandhar.in</nowiki>

<nowiki># dig sandhar.in -t mx</nowiki>

DNS is working internally in the server.

'''4) What are the top issues affecting performance?'''

1: Hardware performance

2: Disk Size (/opt partition )

3: Network performance

4: Server Memory ( RAM )

'''5) How do I change the Zimbra server's hostname, IP address and credentials?'''

1: Changing Zimbra server hostname is not adviseable cause everything intenally works with name, if needed and very important then have to analyse the effect at that moment have proper downtime and then can be done only by Us cause it might affect all the services and a very risky thing to do.

2: IP address and credentials

As the server is behind the firewall the credentials were simple but not adviseable that can be changed after informing us

node1: 172.17.16.97 : [mailto:root@4321 root@4321]

node2: 172.17.16.98 : root123

archive: 172.17.16.99 : root123

node: 172.17.16.22: its a floating IP between node1 and node2

'''6) How to restore mails from archive server?'''

1<sup>st</sup> login to the archive server switch user to zimbra

let take the example for the amit.sharma1

hit the below commands

$ zmprov gmi [mailto:amit.sharma1@archive.sandhar.in amit.sharma1@archive.sandhar.in]

above command will give the mailbox id suppose it give 33 then go to directory

$ cd /opt/zimbra/store/0/

$ rsync -aP 33 [mailto:root@192.168.1.22 root@172.17.16.22]:/tmp/ # it will prompt for the password of machine 22 provide it then the directory will transfer to the server

Now login to 172.17.16.22 and check the directory was there or not by below command.

<nowiki># ls /tmp/</nowiki>

above will show a directory maned 33, now change the permission of the directory so hat zimbra can work on it as with below command.

<nowiki># chown zimbra.zimbra /tmp/33 -R</nowiki>

<nowiki># su – zimbra</nowiki>

$ zmmailbox -zadmin

mbox> selectMailbox [mailto:amit.sharma1@sandhar.in amit.sharma1@sandhar.in]

mbox [mailto:amit.sharma1@sandhar.in amit.sharma1@sandhar.in]> creatFolder /Recovery

mbox [mailto:amit.sharma1@sandhar.in amit.sharma1@sandhar.in]> addMessage /Recovery /tmp/33/

<nowiki>#/tmp/33 is the path of the folder in which acrive mails were there.</nowiki>

Note: Please do not do the above without under our observation till you haven't have a good experince with cli and understanding of the process.

'''7) Since there is no password restriction on mailing group, what would be best practice for restricting users from sending mails to " everyone "'''

There is a process on group restricting that only who can delever the mail on that particular group, which can be done at backend via CLI only.

'''8) How can we increase or decrease mail size quota?'''

There is no Such option of mail size quota, its a users mailbox quota which can be maintain via GUI admin panel

login to Admin Panel and hit below

Manage -->> [mailto:user@sandhar.in user@sandhar.in] -->>double click on user, go to advance in the left pane, and set the quota accordingly, 0 stands for unlimited quota.

'''9) How to create a mail ID?'''

Login to Admin Panel hit the below.

Manage -->> click on the right corner most setting tab, click on New and follow the instruction accordingly.

'''10) How to create diff groups?'''

Login to Admin Panel hit below

Manage -->> click on distribution list, and follow the instruction accordingly.

'''11) Is there any daily checklist of the best practice which can be reviewed on daily basis to check whether the Zimbra mailing server and its all services ar functioning properly'''

For this nagios client can be implemented on the server as you were having the nagios server.

'''12) How to configure archive server ? SOP for the same.'''

== Introduction ==
This document shows how to create a simple archiving server. If you have a user 'keyur@example.com', all mails sent to and from this email ID will be forwarded to 'keyur@archive.example.com'. We will need two servers for this. Both will be installed with Zimbra, one being the live mail server 'example.com', and the other the archiving server, 'archive.example.com'. The archiving server should have a much larger HDD drive than the mail server, preferably formatted using LVM, to allow for expansion later.

The installation on each server will be independent, ie, this isn't a multi-server setup. Each server will be a single-server, with the only difference being the domain names.

In this example, let's assume the live server's domain is 'example.com', with IP 192.168.1.5, and the archiving server is 'archive.example.com', with IP 192.168.1.18. Install Zimbra on both as usual.

== DNS ==
The servers will require a local DNS, as we use this to forward the mails. In this example, I will assume that we have set up a caching name server using bind on the live server. Typical entries would be something like this:

example.com. IN A 192.0.43.10

mail.example.com. IN A 192.168.1.5

example.com. IN MX 10 mail.example.com.

Along with this, we need to add an A and MX record for archive.example.com as well.

archive.example.com. IN A 192.168.1.18

archive.example.com. IN MX 10 archive.example.com.

Now all mails addressed to 'archive.example.com' will be forwarded to the archive server.

== Postfix ==
In postfix, we can specify an email address to which all incoming and outgoing mails from a particular email ID will be forwarded to. This is done using 'sender_bcc_maps' and 'recipient_bcc_maps'. All these changes are done only on the main server. We make the following entries at the end of /opt/zimbra/postfix/conf/main.cf

sender_bcc_maps = hash:/opt/zimbra/postfix/conf/archivelist

recipient_bcc_maps = hash:/opt/zimbra/postfix/conf/archivelist

The file '/opt/zimbra/postfix/conf/archivelist' will have users in the following format: keyur@example.com keyur@archive.example.com All mails to and from keyur@example.com will be forwarded to keyur@archive.example.com.

== Manual addition ==
Create a user on the main server, and then the corresponding user on the archive server. Then add the users in the format as show above to the file '/opt/zimbra/postfix/conf/archivelist', and then run the postmap command as the zimbra user:

$ postmap /opt/zimbra/postfix/conf/archivelist

$ postfix reload
