With the SMTP connector, e-mails can be delivered to the archive via the standardised SMTP protocol.
Various mail servers (e.g. Postfix under Linux) can automatically create a copy of an e-mail when it arrives and forward it via SMTP to another mail server. In this case, the SMTP connector must be specified as the mail server.
The following steps are necessary to configure the SMTP connector:
Click on "Start Service".
Click on Activate in the General tab
Select the network interface and the corresponding port under which the SMTP connector is to be accessible (if port 25 is to be selected here, the eth0:MDcon interface must be activated).
In cluster mode, the interface "ANY" should be used here; eth0:MDcon cannot be used for clusters.
Set the host name with which the STMP service should report to Helo and select a connection timeout (default 30 seconds).
Activate TLS in the TLS Settings tab, if desired, and select the certificate to be used (this must be created in advance in the Admin Web Interface -> Configuration -> SSL Certificates) as well as the desired TLS mode and permitted protocols.
In the Authentication tab you can create an IP address restriction line by line in IPv4 format and store access data that should be necessary for a login.
In the tab extended you can determine which addresses from the e-mail are to be used for the creation of the access authorisation.
SMTP envelope, mail header and static addresses are possible.
In addition, you can set message tags (Use Custom message type tag) to give each e-mail a tag that can later be queried via the Advanced Search in Expert Mode.
The tag must be a number greater than or equal to 10000.
The maximum mail size for archiving is set to 100 MB by default. You can adjust this up to a maximum of 999 MB, but please note that the working memory must be dimensioned accordingly.
Save the settings using the "Save Settings" button.
Overview of the ACL options in step 7:
SMTP Envelope only
For the assignment of the e-mail to the respective user, the recipient address is taken from the transmission protocol.
This method is not suitable for journal-based e-mail archiving, but rather for delivering mail systems (including specially created scripts) that specify the recipient addresses individually in the SMTP dialogue using "RCPT TO:".
Mail header only
For the assignment of the e-mail to the respective user, the recipient address is taken from the header of the e-mail (To:).
SMTP Envelope and Mail Header
For the assignment of the e-mail to the respective user, the recipient address is taken from the transmission protocol as well as from the header.
In the archive, therefore, those e-mails are displayed which contain one of the two addresses for which the user is responsible.
Additional Static Addresses
Additional static e-mail addresses that receive access to these e-mails archived via the SMTP connector. Wildcards or group-forming characters (Regular Expressions) such as "*" are not allowed. Only use unique addresses.
In the POP3 connector, mailboxes can be configured which are regularly read out via the POP3 protocol.
E-mails in the mailbox are transferred to the connector's spooler and then deleted.
The retrieved e-mails are then transferred to the central archive spooler, where they are archived in the standard container.
The following steps are necessary to configure the POP3 connector:
Click on Add
Activate the POP3 profile with "Activated"
Enter the connection parameters to the POP3 server (host name, port, connection security, user name, password, pick-up interval, timeout).
In the Advanced tab, you can configure additional static e-mail addresses for access authorisation (additional e-mail addresses that are to have access to these e-mails, only regular addresses, no wildcards) as well as optionally set a Custom message type (message tag so that this tag can later be searched for in the Advanced Search in Expert Mode).
The custom message type tag must be a number greater than or equal to 10000.
The maximum mail size for archiving is set to 100 MB by default. You can adjust this up to a maximum of 999 MB, but please note that the RAM must be dimensioned accordingly.
Save the settings with "Save"
If the retrieval of a POP3 mailbox fails with the error "An error occurred while attempting to establish an SSL or TLS connection", the target server does not support current SSL algorithms.
In this case either the target server must be updated, or a retrieval without TLS must be configured.
With the directory watcher, e-mails that have been stored as a file in the specified directory can be retrieved and stored directly in the central archive spooler.
The e-mail file is then deleted from the monitored directory.
The following steps are necessary to configure the directory monitoring:
Click on Add and select "Enabled".
Select the path to be monitored and whether subfolders should also be searched.
Configure the search parameter (e.g. *.eml)
Set the interval for checking the directory
In the Advanced tab, you can configure additional static e-mail addresses for access authorisation (additional e-mail addresses that should have access to these e-mails, only regular addresses, no wildcards) as well as optionally set a Custom message type (message tag, so that later in the Advanced Search in Expert Mode this tag can be searched for).
The custom message type tag must be a number greater than or equal to 10000.
The maximum mail size for archiving is set to 100 MB by default. You can adjust this up to a maximum of 999 MB, but please note that the working memory must be dimensioned accordingly.
Save the settings with "Save"
You can grant further access rights via an ACL file, both at directory level and on an e-mail file basis.
Directory-wise
Create a text file called rdxmaildepot.rdxacl in the desired subdirectory.
Enter the desired email addresses for which the additional permission is to be granted, line by line.
The addresses must be unique, wildcards etc. are not allowed and will not be considered.
