Administrators can combine Postfix with other software that provides spamvirus filtering e. Amavisd new, message store access e. Suzuki Alstare Extreme Racing Game Pc on this page. Dovecot, or complex SMTP level access policies e. As an SMTP client, Postfix implements a high performance parallelized mail delivery engine. Postfix is often combined with mailing list software such as Mailman. Operating systemseditPostfix runs or has run on AIX, BSD, HP UX, Linux, mac. OS, Solaris and, generally speaking, on every Unix like operating system that ships with a Ccompiler and delivers a standard POSIX development environment. It is the default MTA for the mac. OS, Net. BSD4 and Ubuntu operating systems. ArchitectureeditPostfix consists of a combination of server programs that run in the background, and client programs that are invoked by user programs or by system administrators. The Postfix core consists of several dozen server programs that run in the background, each handling one specific aspect of email delivery. Examples are the SMTP server, the scheduler, the address rewriter, and the local delivery server. For damage control purposes, most server programs run with fixed reduced privileges, and terminate voluntarily after processing a limited number of requests. To conserve system resources, most server programs terminate when they become idle. Bulk Mail Software Linux' title='Bulk Mail Software Linux' />Client programs run outside the Postfix core. They interact with Postfix server programs through mail delivery instructions in the users. Other programs provide administrative support to start or stop Postfix, query status information, manipulate the queue, or to examine or update its configuration files. Yellow ellipses. One of Postfix many daemons serving exactly one purpose. This split up into many smaller pieces of software is considered one of the reasons why Postfix is secure and stable. Blue boxes. The blue boxes represent so called lookup tables. A lookup table consists of two columns key and value containing information used for access control, e mail routing etc. Yellow boxes. The yellow boxes are either mail queues or files. In either case, e mails are stored on persistent media e. White clouds. The clouds stand for points at which e mails enter or leave Postfix. For example, smtpd receives mail from other mail servers or users whereas smtp relays mail to other MTAs. ImplementationeditThe Postfix implementation uses safe subsets of the C language and of the POSIX system API. These subsets are buried under an abstraction layer that contains about 5. Postfix source code, and that provides the foundation on which all Postfix programs are built. For example, the vstring primitive makes Postfix code resistant to buffer overflow6 attacks, and the safe open primitive makes Postfix code resistant to race condition attacks on systems that implement the POSIX file system API. This abstraction layer does not affect the attack resistance of non Postfix code, such as code in system libraries or in third party libraries. RobustnesseditConceptually, Postfix manages pipelines of processes that pass the responsibility for message delivery and error notification from one process to the next. All message and notification state information is persisted in the file system. The processes in a pipeline operate mostly without centralized control this relative autonomy simplifies error recovery. When a process fails before completing its part of a file or protocol transaction, its predecessor in the pipeline backs off and retries the request later, and its successor in the pipeline discards unfinished work. Many Postfix daemons can simply die when they run into a problem they are automatically restarted when the next service request arrives. This approach makes Postfix highly resilient, as long as the operating system or hardware dont fail catastrophically. PerformanceeditOne single Postfix instance has been clocked at 3. Internet, running on commodity hardware a vintage 2. Dell 1. 85. 0 system with battery backed Mega. RAID controller and two SCSI disks. This delivery rate is an order of magnitude below the intrinsic limit of 2. RAM disk while delivering to the discard transport with a dual core Opteron system in 2. Mail systems such as Postfix and Qmail achieve high performance by delivering mail in parallel sessions. With mail systems such as Sendmail and Exim that make one connection at a time, high performance can be achieved by submitting limited batches of mail in parallel, so that each batch is delivered by a different process. Postfix and Qmail require parallel submission into different MTA instances once they reach their intrinsic performance limit, or the performance limits of the hardware or operating system. It should be noted that the delivery rates cited above are largely academic. With bulk mail delivery, the true delivery rate is primarily determined by the receivers mail receiving policies and by the senders reputation. Base configurationeditThe main. Postfix configuration parameters while master. The Postfix Basic Configuration tutorial covers the core settings that each site needs to consider, and the Postfix Standard Configuration Examples document discusses configuration settings for a few common environments. The Postfix Address Rewriting document covers address rewriting and mail routing. The full documentation collection is at Postfix Documentation. More complex Postfix implementations may include integration with other applications such as Spam. Assassin support for multiple virtual domain names and use databases such as My.
