  • Name Synopsis Description
    SMTPSERVER(8zm) SMTPSERVER(8zm) NAME smtpserver − zmailer SMTP server SYNOPSIS smtpserver [-46aBhigntVvw][-p port][-l SYSLOG][-l logfile][-s[ftveRSDh]] [-s strict] [-s sloppy][-I pidfile][-L maxloadaver][-M SMTPmaxsize][-P postoffice][-R router] [-C cfgfile][-Z zenvfile][-T '[1.2.3.4]'] DESCRIPTION This program implements the server side of the SMTP protocol as defined in RFC-2821, and knows about the common extensions to the protocol expected by sendmail and BSMTP clients. By default the program will kill the previous smtpserver (8zm) daemon, if any, then detach and lis- ten for SMTP connections. Incoming messages will be submitted for processing using the zmailer (3zm) interface to ZMailer. Non-trivial address checking is done asynchronously, although this behaviour can be changed by a command line option if you cannot afford to transfer data just to bounce it back. Complex routing analysis checking is done by executing the router (8zm) program in interactive mode, and executing a well-known shell function with well-known parameters for each request. Traditionally this task has needed starting router process (and some other processes) underneath each incoming SMTP session, which is not a very lightweight thing. Current version has prestarted farm of auxiliary server processes that can be used to handle com- plex things, and they can amortize e.g. router startup cost among lots of actual users making the use of routing in reception time very cheap in terms of resources. Presently system starts a master process that starts a set of auxiliary processes, and keeps inter- nal nameless rendezvous sockets for each of them.
