<h2><a name="oct_12__2005_v_1_22">Oct 12, 2005 v 1.22</a></h2>
<ul>
<li></li>
The POP3 before SMTP authentication is now correctly interpreted as real SMTP authentication,
by the mean of @@USERAUTH.
<p></p>
<li></li>
'<strong>ATTENTION</strong>': Fixed a possible cause of buffer overflow in the XMail's sendmail binary.
<p></p>
<li></li>
Changed the DNS MX resolution to allow better handling of partially broken DNS servers
configuations.
<p></p></ul>
<p>
</p>
<h2><a name="jan_9__2005_v_1_21">Jan 9, 2005 v 1.21</a></h2>
<ul>
<li></li>
Added a fix for 64 bits porting compatibility.
<p></p>
<li></li>
Added the ability to exclude filters from execution in case of authenticated user.
By pre-pending the filter command token with a token containing ``!aex'', the filters
won't be run if the user authenticated himself.
<p></p>
<li></li>
Added @@USERAUTH macro even to standard in/out filters (before it was only defined
for SMTP ones).
<p></p>
<li></li>
Added a new ``NoSenderBounce'' variable inside the SERVER.TAB file, to enable
XMail generated bounce messages to have the empty SMTP sender ('MAIL FROM:<>').
<p></p>
<li></li>
Added a new ``SMTP-MaxErrors'' variable inside the SERVER.TAB file to set the maximum
errors allowed in a single SMTP session (default zero, unlimited).
<p></p>
<li></li>
Added a ``LastLoginTimeDate'' variable to the ``userstat'' CTRL command.
<p></p>
<li></li>
Added external aliases support in the CTRL protocol.
<p></p>
<li></li>
The MESSAGE.ID file is now automatically created, if missing.
<p></p>
<li></li>
Changed the logic used to treat domain and user MAILPROC.TAB files. Before, a user's
MAILPROC.TAB was overriding the domain one, while now the rules are merged together,
with domain's ones first, followed by user's ones.
<p></p>
<li></li>
The maximum mailbox size of zero is now interpreted as unlimited.
<p></p>
<li></li>
Fixed XMail's sendmail to detect non-RFC822 data and handle it correctly.
<p></p>
<li></li>
The IP:PORT addresses emission in spool files (and Received: lines) has been changed
to the form [IP]:PORT.
<p></p>
<li></li>
Added filter logging, that is enabled with the new -Qg command line option.
<p></p>
<li></li>
Fixed an error message in the SMTP server, that was triggered by the remote client
not using the proper syntax for the ``MAIL FROM:'' and ``RCPT TO:'' commands.
<p></p>
<li></li>
Fixed explicit routing through SMTPGW.TAB file.
<p></p>
<li></li>
Fixed a possible problem with file locking that might be triggered from CTRL commands
cfgfileget/cfgfileset.
<p></p>
<li></li>
Added a check to avoid the CTRL server to give an error when a domain created with
older versions of XMail does not have the domain directory inside cmdaliases.
<p></p>
<li></li>
The SMTP server FQDN variable should be set to the value of ``SmtpServerDomain'', when
this is used inside the SERVER.TAB file.
<p></p></ul>
<p>
</p>

</p>
<h2><a name="may_29__2004_v_1_19">May 29, 2004 v 1.19</a></h2>
<ul>
<li></li>
Implemented the ``filter'' command for custom mail processing (MAILPROC.TAB, cmdaliases
and custom domains).
<p></p>
<li></li>
If ``RemoveSpoolErrors'' is set inside the SERVER.TAB file, messages are never frozen.
Before there was a special case (delivery failure and delivery notification failure)
that could have lead to frozen messages.
<p></p>
<li></li>
Made ``aliasdomainadd'' to check for the existence of the alias domain (and reject
the command if existing).
<p></p>
<li></li>
Introduced a new environment variable recognized by XMail (XMAIL_PID_DIR), to let
the user to specify a custom PID file directory (this is for Unix ports only).
<p></p>
<li></li>
Implemented ability to stop custom mail processing upon certain exit codes from
external commands execution.
<p></p>
<li></li>

<p></p>
<li></li>
Made (on Unix setups) the PID file name to be dependent on the daemon file name.
<p></p>
<li></li>
Implemeted a domain-wise MAILPROC.TAB and extended its ``redirect'' and ``lredirect''
commands to support account specific (USER@DOMAIN) and domain targets (DOMAIN).
<p></p>
<li></li>
Implemented SMTP filters to allow users to reject the SMTP session before and
after the remote client data has been received.
<p></p></ul>
<p>
</p>
<h2><a name="mar_27__2004_v_1_18">Mar 27, 2004 v 1.18</a></h2>

as a consequence of this, the system dependent portion of XMail (SysDep*).
<p></p>
<li></li>

<p></p>
<li></li>
Fixed the alias lookup to perform a better ``best match'' wildcard selection.
<p></p>

does not contain one. The environment variable (or registry in Windows) DEFAULT_DOMAIN is
looked up to try to complete the address.
<p></p>
<li></li>
Fixed a bug in the return code of <code>SysAccept()</code> in all Unix versions.
<p></p>
<li></li>
Fixed a bug that was triggered by external command and filter exiting soon. XMail was not
able to correctly sync with the child process by losing it. This apply only to Unix
versions of XMail.
<p></p>
<li></li>
A notification message is now sent to the sender if the message is handled with
``smtp'' or ``smtprelay'' commands and a permanent error happen when sending to the
remote SMTP server.
<p></p></ul>
<p>

the SMTP client does authenticate with the server.
<p></p>

<p></p>
<li></li>
The POP3 server now picks up messages even from the Maildir's ``cur'' subdirectory.
<p></p></ul>

the name to send as HELO domain (look at variable documentation).
<p></p>
<li></li>
If 'HeloDomain' is not specified or if empty then the reverse lookup of the local IP is sent as HELO domain.
<p></p>
<li></li>
Added a new SERVER.TAB variable 'DUL-MAPSCheck' to implement the 'dialups.mail-abuse.org' maps check.
<p></p>
<li></li>
Changed the meaning of the SERVER.TAB variables SMTP-RDNSCheck, RBL-MAPSCheck, RSS-MAPSCheck,
ORBS-MAPSCheck and DUL-MAPSCheck to give XMail the ability to delay SMTP commands for clients that fail the check.
<p></p>
<li></li>
The old behaviour (dropped connection) is obtained by setting values greater than zero,
while You can set the delay (in seconds) by specifying negative values.
<p></p>
<li></li>
For SMTP-RDNSCheck and DUL-MAPSCheck variables the connection is no more dropped at welcome time but
a 'server use forbidden' message is given at MAIL_FROM time.
<p></p>
<li></li>
In this way XMail give authenticated users the ability to get in from 'mapped' IPs.
<p></p>
<li></li>
Fixed a bug that cause XMail to crash if there is an empty line in a MLUSERS.TAB file.

that has had delivery errors.
<p></p>
<li></li>
The feature to force XMail to initiate a PSYNC transfer has been added. This is implemented by making XMail
to check for a file named '.psync-trigger' inside MAIL_ROOT. When this file is found a PSYNC tranfer
is started and the file is deleted.

********************************************************************
* A new spool format has been coded to enable XMail to handle very

* See section 'XMail spool design' for a description of how the spool
* works.
* Due to the new spool format the following directories can be
* removed:
*
* custdomains/spool
* spool/tmp
* spool/errors
* spool/logs
* spool/locks
*
* You've to leave XMail flush its queue (spool) before upgrading
* to this version.
* A more complex solution, if You've a lot of file pending into the
* spool, is :
*
* 1) Stop XMail
* 2) Upgrade to 0.61
* 3) Start XMail and wait it has created all the queue tree structure
* 4) Stop XMail
* 5) Move all old spool/ files into 0/0/mess
* 6) Rename all spool/logs/ files removing the .log extension
* 7) Move all spool/logs/ file into 0/0/slog
* 8) Now You can remove the above directories and restart XMail
