MailServer邮件服务器端源代码

NAME XMail Change Log as of Version 1.20 [top] CHANGE LOG May 30, 2004 v 1.20 * Fixed a possible memory leak and a possible source of crashes. May 29, 2004 v 1.19 * Implemented the "filter" command for custom mail processing (MAILPROC.TAB, cmdaliases and custom domains). * 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. * Made "aliasdomainadd" to check for the existence of the alias domain (and reject the command if existing). * 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). * Implemented ability to stop custom mail processing upon certain exit codes from external commands execution. * The SPAMMERS.TAB check is now bypassable (see doc for details). * 'ATTENTION': Changed the "aliasdomainlist" syntax and output format (see doc for details). * Made (on Unix setups) the PID file name to be dependent on the daemon file name. * Implemeted a domain-wise MAILPROC.TAB and extended its "redirect" and "lredirect" commands to support account specific (USER@DOMAIN) and domain targets (DOMAIN). * Implemented SMTP filters to allow users to reject the SMTP session before and after the remote client data has been received. Mar 27, 2004 v 1.18 * Restructured the external program execution environment on Unix ports. Simplified, as a consequence of this, the system dependent portion of XMail (SysDep*). * Fixed a bug in the address range parsing (x.y.w.z/s). * Fixed the alias lookup to perform a better "best match" wildcard selection. * Fixed a bug in the DNS resolved that made XMail to not correctly handle domain CNAMEs. Sep 14, 2003 v 1.17 * Added Bcc: removal from message headers in XMail's sendmail. * Added PSYNC logging (-Yl). * Added domain completion to XMail's sendmail when the specified sender address (-f or -F) does not contain one. The environment variable (or registry in Windows) DEFAULT_DOMAIN is looked up to try to complete the address. * Fixed a bug in the return code of SysAccept() in all Unix versions. * 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. * 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. Jul 8, 2003 v 1.16 * Added a new configuration file "smtp.ipprop.tab" to be able to specify peer IP based configuration option, like for example IP white listing against IP checks. * 'ATTENTION': The filter return code has been changed and new return codes are expected to be returned by filters. Please che the documentation and update your filters before starting to use the new version. * Added the ability to specify a custom error message for filters. * Fixed a bug in the string quoting function that showed up when the string was empty (""). * Changed the order used by XMail to check the mailer domain. Now MX check is performed first, then A record check. This caused a slow down for domains having MX records but not A records. * Added two new Received: types to give the ability to hide client information if the SMTP client does authenticate with the server. * Added the rejection map name inside the SMTP log file in case of SNDRIP=EIPMAP error. * Modified XMail's sendmail to add the RFC822 Date: header if missing. * XMail now uses the name of the executable ( without .exe ) to both register the service name and fetch registry variables. * The POP3 server now picks up messages even from the Maildir's "cur" subdirectory. May 3, 2003 v 1.15 * Implemented a new filters feature that enable the user to stop the selected filters list processing upon receival of certain exit codes. * Fixed the wrong log file name generation when the daylight time is active. * Fixed a bug inside the DNS MX resolver. * Fixed a bug ( Windows OS bug ) that made XMail unable to create domains starting with reserved device names ( COM#, LPT, PRN, CON, ... ). So, for example, a domain named "com4.domain.org" couldn't be created because of this naming conflict. * Fixed a bug that made XMail to not apply filters for local mailing list. * Fixed a bug that made XMail to crash under certain conditions. April 2, 2003 v 1.14 * Added a "Server:" field to the notification message. It'll report the remote SMTP server host name and IP that issued the error. It will not be present if the error does not originate from a remote SMTP server. * Added a new command line parameter -MD to set the number of subdirectories allocated for the DNS cache files storage. * Messages with non RFC822 conforming headers are now handled by the PSYNC code. * 'ATTENTION': The filter architecture has been completely changed. To correctly update to this version you have to create two empty files "filters.in.tab" and "filters.out.tab" inside the $MAIL_ROOT directory. Please refer to the documentation for more information about the new filter architecture. If you are not currently using filters, the simple creation of the two files listed above will be sufficent. * 'ATTENTION': The internal spool file format is changed with the new line added ( the 1st one ) that contain various message information. Filters that rely on the internal spool file format must be changed to match the new structure. * Fixed a bug that made XMail to not correctly report zero sized files inside the mailbox. * Added file size to CTRL's "filelist" command. * Fixed a connect-error reporting bug on Windows platform. January 25, 2003 v 1.12 * Better check for user/domain names. * Changed search pattern for filters. Now a domain name is scanned for all sub-domains. * Fixed a boundary check inside the Base64 decoder. * Added the client FQDN inside the SMTP log file in case the RDNS check is enabled. * Added a new SERVER.TAB variable "SmtpMsgIPBanSpammers" to set the message that is sent to the SMTP client when the client IP is listed inside the file SPAMMER.TAB. = item * Added a new SERVER.TAB variable "SmtpMsgIPBanMaps" to set the message that is sent to the SMTP client when the client IP is listed inside one of the "CustMapsList". * Added a new SERVER.TAB variable "SmtpMsgIPBanSpamAddress" to set the message that is sent to the SMTP client when the client IP is listed inside the file SPAM-ADDRESS.TAB. * Fixed a bug inside the custom account handling that made XMail to pass the old password instead of the new one. * Added OpenBSD support. November 9, 2002 v 1.11 * Added a new command line parameter -QT to enable a configurable timeout for filter commands. * Fixed a bug that made XMail to ignore cmdalias accounts when a wildcard alias was matching the account itself. * Added the 'smtprelay' command to the MAILPROC.TAB processing.
