| − | '''Please note:''' this tutorial only covers the specifics of archiving an email server based on the mail transfer agent Exim. It is assumed that you already have a MailStore Server installation or [http://www.mailstore.com/en/lp/sendlicense.aspx test installation] and are familiar with the fundamentals of MailStore Server. Please refer to the [[Manual]] or the [http://www.mailstore.com/en/doc/server4-quickstart-en.pdf Quick Start Guide] for more information.

| − | | |
| − | MailStore Server offers several ways to archive emails from Exim, which are described below. If you are not sure which archiving method best suits your company, please refer to chapter [[Choosing the Right Archiving Strategy]].

| − | | |
| − | Alternatively to local file-based user databases, an email server based on the mail transfer agent Exim may use SQL databases or LDAP directory services to manage and authenticate users. As MailStore Server also supports Active Directory and other LDAP directory services (e.g. OpenLDAP) you can find additional information on synchronizing users in the corresponding chapters of the MailStore Server manual:

| |
| − | | |
| − | '''Note:''' When [[Batch-archiving IMAP Mailboxes|batch-archiving IMAP mailboxes]] MailStore Server automatically creates non-existing users. The authentication type of those users will be ''MailStore-integrated''.

| − | Mail transfer agents such as Exim are only responsible for transporting emails and, when acting as mail delivery agent, for the delivery to local mailboxes. For accessing the emails in the mailboxes with MailStore, an IMAP- or POP3 service (called mail retrieval agent) must be installed and started on the email server. If access to the email server via the IMAP and/or POP3 protocol is possible, please refer to the corresponding chapter [[Archiving Server Mailboxes]] in the MailStore Server manual to set up the archiving process.

| − | | |
| − | In addition to delivering the messages to their respective user mailboxes, it is recommended to have Postfix send a copy of all emails to an archiving mailbox when archiving incoming and outgoing emails. This requires a new router as well as a new transport to be added in the Exim configuration.
| |
| − | | |
| − | == Step 1: Adding an Exim Router ==
| |
| − | | |
| − | The configuration of the new Exim router should look like this:
| |
| − | | |
| − | mailstore_router:
| |
| − | no_expn
| |
| − | no_verify
| |
| − | transport = mailstore_transport
| |
| − | driver = accept
| |
| − | unseen
| |
| − | | |
| − | Please make sure that the ''mailstore_router'' is passed through before the router responsible for delivering the messages to the actual user mailboxes.
| |
| − | It is strongly recommended to enter it first in the Exim router configuration. Depending on your anti-spam or anti-virus protection it may also be suitable to put it right after the routers handling those actions.
| |
| − | | |
| − | == Step 2: Adding an Exim Transport ==
| |
| − | The above router calls a transport called ''mailstore_transport'' which has to be set up next. A new transport can be put anywhere in the Exim transport configuration. The following example shows the configuration of an Exim transport storing all emails in ''Maildir'' format in the directory ''/var/mailstore/Maildir''. To store messages in a different location, please refer to the Exim manual.
| |
| − | | |
| − | mailstore_transport:
| |
| − | driver = appendfile
| |
| − | delivery_date_add
| |
| − | envelope_to_add
| |
| − | return_path_add
| |
| − | maildir_format = true
| |
| − | create_directory = true
| |
| − | directory = /var/mailstore/Maildir
| |
| − | | |
| − | To retrieve emails from the mailbox there must exist a system user whose mail home directory points to ''/var/mailstore/Maildir''. In most cases, e.g. if using a Dovecot IMAP server, it is sufficient to have a system user whose home directory points to ''/var/mailstore''.
| |
| − | | |
| − | == Step 3: Configuration of MailStore Server ==
| |
| − | Configure MailStore Server to archive the newly created mailbox in regular intervals (e.g. daily at 11pm) using an archiving task of type [[Archiving IMAP and POP3 Multidrop Mailboxes]].
| |
| − | | |
| − | After archiving, emails can and should be deleted from the MDaemon mailbox automatically by MailStore Server. The MailStore archiving task can be configured accordingly.
