Xmail server lite installation




















The contents of your Inbox folder will be displayed upon log in. The Mailbox Listing shows the contents of each message header message status, date sent, sender, subject, and size.

Each column has a heading. Clicking on the heading will cause the listing to be sorted by that column. To view the contents of a message, double click on the message subject. You'll be taken to the Message screen. From here, you can browse message attachments, reply to the current message, delete the current message, or advance to the next message in your current mailbox.

Plain Text messages are displayed by default. To view an attachment click on the hyper-linked name, or open it by clicking on the download image located at the right side of the screen. Then click on "Submit" you will be brought to the log-in page and just log in with the details you just set. Once in you can start to create your mail users or configure other settings as needed. To uninstall Xmail: Simply delete the entire chroot environment. So does it really work? As for details regarding the server config and how to use Xmail, I guess I'll leave that to you with the information and resources below.

Suppose a filter modified the message and hence needs to return 7 as return code. Suppose also that a filter wants to block the filter selection list processing by specifying a flags value of 16 , the value to be returned will be :. The "sender" and the "recipient" are resolved to the real account when possible. TAB ' lists filters that have to be applied to outbound messages delivered remotely.

The syntax of the filter file is:. Each file may contain multiple commands, that will be executed in strictly sequential order. The first command that will trigger a rejection code will make the filtering process to end. The ' flags ' parameter is a comma-separated list of flags that drives the filter execution. Currently supported flags are:. TAB file. This flag works only for SMTP filters. Here ' command ' is the name of an external program that processes the message and returns its processing result.

If it returns ' 6 ' the message is rejected and a notification message is sent to the sender. By returning ' 5 ' the message is rejected without notification.

While returning ' 4 ' the message is rejected without notification and without being frozen a ' 5 ' response could lead to a frozen message if the SERVER. TAB configuration enables this. If all filters return values different from ' 6, 5 and 4 ' the message continues its trip. The filter command may also modify the file AV scanning, content filter, message rewriting, etc by returning ' 7 '. The filter ' MUST ' return ' 7 ' in case it modifies the message.

The message is composed of a headers section and, after the first empty line, the message body. The format of the "Info Data" line is:.

Besides having the ability to perform off-line message filtering, XMail gives the user the power to run filters during the SMTP session. Using such filters, the user can tell XMail if or if not accept the following transaction and, in case of rejection, the user is also allowed to specify a custom message to be sent to the remote SMTP client. TAB ' contains zero or more lines with the following format:.

For post-rcpt filters, this will be used as to-validate recipient. Filter commands have the ability to inspect and modify the content of the message or info file. The exit code of commands executed by XMail are used to tell XMail the action that has to be performed as a consequence of the filter.

The exit code is composed by a raw exit code and additional flags. Currently defined flags are:. Such file will be automatically removed by XMail. The format of the RCPT line is:.

Otherwise it holds the same value of "address". In case one or more SMTP filter operations are not needed, avoid to create zero sized files altogether, since this will result in faster processing. This variable should be set to avoid delivery error notifications to reach the original message senders. Set to '1' if the account can receive email, '0' if you want to disable the account from receiving messages. Set the maximum message size in Kb that the user is able to send through the server.

TAB variable. Valid values are '0' or '1', default is '0' emission enabled. TAB one when present. In case of Maildir mailbox structure, scan the "cur" directory during POP3 message list build.

Set to "0" to disable "cur" directory scanning, or to "1" to enable it. The new spool filesystem tree format has been designed to enable XMail to handle very large queues. Instead of having a single spool directory like versions older than 0.

When XMail needs to create a new spool file a spool path is chosen in a random way and a new file with the format:. When the spool file is ready to be committed, it's moved into the ' mess ' subdirectory that holds newer spool files. If XMail fails sending a new message the ones in mess subdirectory it creates a log file with the same name of the message file inside the ' slog ' subdirectory and move the file from ' mess ' to ' rsnd '.

During the message sending the message itself is locked by creating a file inside the ' lock ' subdirectory with the same name of the message file. TAB ' file is off, the message file is moved into the ' froz ' subdirectory. Currently defined options are:. XMail uses to identify itself during SSL negotiations, by the mean of the two files ' server. For Unix ports, this is available as a package, whose name varies depending on the distribution.

For Windows, pre-built versions of theOpenSSL libraries and binary are supplied inside the "win32ssl" directory of the XMail source package.

For example, to create a self-signed certificate, you first have to create a private key with:. After you have created the private key, you can create you own copy of the self-signed certificate with:. If you want to have a certificate signed by an authority, you need to generate a certificate request file:.

The ' openssl. The ' cert. TAB ' variables:. Tells the SSL link negotiation code to verify the remote peer certificate. You can also add your own certificates in the set, in order to provide access to your servers by clients using certificates signed by you. Most of XMail configuration settings are command line tunables. These are command line switches organized by server. Set the queue split level.

The value you set here is rounded to the lower prime number higher or equal than the value you've set. Set POP3 session timeout seconds after which the server closes. Set the delay timeout in response to a bad POP3 login. Such time is doubled at the next bad login. Set SMTP session timeout seconds after which the server closes the connection if no commands are received.

Set the increment ratio of the reschedule time in sending a messages. Set external POP3 accounts sync interval. Default Set CTRL session timeout seconds after which the server closes the connection if no commands are received. The XMail admin server 'speaks' a given protocol that can be used by external GUI utilities written with the more disparate scripting languages, to remote administer the mail server.

The protocol is based on sending formatted command and waiting for formatted server responses and error codes. The " character is not included in responses. As the first action immediately after the connection the client must send an authentication string with this format:. Clear text authentication should not be used due server security. If the user does not receive a positive authentication response, the connection is closed by the server.

It is possible to establish an SSL session with the server by issuing the "! TLS" string as login string.
