Mail Server Settings

FossLook installation includes a standalone mail server, which enables you to run the mail services in your domain. FossLook server also allows users to connect external mailboxes from other email providers (yahoo.com, gmail.com, etc.). This article describes in detail all mail server settings, as well as gives basic instructions on how to setup and configfure your personal mailboxes. Instructions on how to create and work with external mailboxes are described in a separate.

If you already have an email account and you simply want to add it in FossLook client, you can find more information on how to do it in our article: Configuring Additional Mailbox.

"Network" Tab

To configure the server, start FossLook Administrator and select "Network" tab. This is the main page of the mail server settings. Here you can setup different server parameters such as "Internet mail account settings", "Mail server settings", "External accounts settings", "Channels".

Channels

Channels, is the most important dialog of this section. After configuring basic parameters here, you will be able to create and work with internal email addresses that use your custom domain name.

The following list shows the dialog sections, with a description of the purpose of each:

"SMTP Settings" Section

• Use – enables or disables the SMTP-protocol.
• Port – port number to use via SMTP-protocol.
• Certificate – information about the certificate used for encryption
• SSL Port – port number for the encrypted exchange.

"POP3 Settings" Section

• Use – enables or disables the ability to exchange between the FossLook server and external e-mail clients other than MS Outlook.
• Port – port number for the POP3 protocol messaging.
• Certificate – information about the certificate used for encryption.
• SSL Port – port number for the encrypted exchange.

"Routing" Section

• Domain name – domain name of the computer on which the FossLook server is installed.
• FQDN – full domain name of the computer on which the FossLook server is installed.
• Network interface –IP-address of the network adapter on the FossLook server, which has connection to the Internet.
• Do not receive more than – maximum size limit of the incoming messages.
• Frame relay – domain name or IP-address of an intermediate server, which will receive all the correspondence, from which it will be sent to the addressees later.

"Additional Connection to Server" Section

• Enable – enables or disables the ability to connect to the mail server using an email client Microsoft Outlook.
• Network interface – IP-address of the network adapter on the FossLook server, through which the server is connected to the LAN (if the host has a separate gateway to the Internet), or IP-address of the network adapter on the gateway through which the connection to the Internet is organized (if the FossLook server is installed on this gateway computer).
• Port – port to connect to the FossLook server with Internet.
• External FQDN – qualified domain name or IP-address of the gateway computer connected to the Internet (if the FossLook server is installed on another computer on the LAN, not on the gateway computer).

Internet Mail Transport General Settings

Here you can configure general internet mail transport settings:

The following list contains the dialog description:

• Enabled option – module status, ON or OFF (i.e. Mail Server is ON or OFF).
• Server service folder path – an alternative path to store log files and other service files of the mail server. If it's empty, the default path is used.
• Allow delegating message sending option – allows users to send messages "on behalf of" other user. In other words, a message will be sent from the delegated user.
• Download only unread messages - if enabled, after initial mailbox setup, user receives only unread messages from the server.
• Logging of SMTP, POP3 – logging protocol type. You can specify few options here: disabled, logging to a single file, logging to multiple files (each session is logged in a separate file), you can also additionally include the message body.

Mail Server Settings

Here you can configure basic mail server settings:

The following list contains the dialog description:

• Address translation list – recipient address replacement list; replaces addresses like so: "address to which the letter is sent", "address to which the letter comes".
• Local addresses exception list – list of local addresses that can send emails without requiring authorization.
• "From" addresses exception list – this option works similarly to the "black list" of email addresses, forbidding their reception on the server.
• Messages per session count – maximum possible number of messages that the server can accept via SMTP at once. Messages can be retrieved from both the email clients and other mail servers.
• Maximum message size, Megabytes – maximum message size for sending/receiving on server, MB.
• Allow delete messages by POP3 – permission to delete e-mails when downloading them via POP3 from the mail server.
• Time to resend messages from queue – specifies the period (h:m:s), after which messages will be resent from the queue (if the previous attempt failed).
• Messages resend from queue count – determines the number of retries to send the message from the queue (in the case of unsuccessful previous attempts). If the message was not sent after a predetermined count of attempts, it is transferred to the "Bad Messages" folder.

External Accounts Settings

Here you can configure external email account settings:

The following list contains the dialog description:

• Error reporting period, in minutes – if the problem still occurs after the passage of this period of time, the user will be notified about it.
• Mail checking period – new messages checking interval.
• Download only unread messages – if enabled, after initial mailbox setup, user receives only unread messages from the server. A similar option was described higher, only for internal email accounts

Setting Up Internal Mailbox

To create an internal mailbox for the user on your server, first start FossLook Administrator, then open user properties and click on the "Accounts" tab:

Check the option "Enable internal email". The server will automatically create user mailbox with the same name as the user's login. You can change the mailbox name and other settings by clicking on "Advanced..." button, and then changing necessary parameters for the selected mailbox:

Next, select an appropriate item from the "POP3 Settings" list, - here you can specify server connection settings for the mailbox.

• Use the current server configuration – in this case the option "Allow delete messages on POP3" of "Mail Server settings" dialog will be used.
• Remove copies of the messages on server – after receiving emails their copies will be deleted from server.
• Leave a copy of the messages on server – after receiving emails their copies will remain on server.
