oh, it's not threaded, it's a single thread that uses non-blocking and select to find out if something is to be done.

I'm not tracking port numbers at all. I'm just accepting TCP connections and connecting TCP connections. do i need to do something with port numbers? all the TCP connections have a different fd, so that's not really a problem, is it?

i did make an eventing structure that holds the addrinfo and fd and other stuff

NAME
qpsmtpd-forkserver - Fork-on-demand server for qpsmtpd SYNOPSIS
qpsmtpd-forkserver [options] DESCRIPTION
qpsmtpd-forkserver is the qpsmtpd frontend script which binds to the SMTP TCP socket and forks as clients connect. OPTIONS
--port port, -p port Binds to a specific port, instead of the default 2525. --user user, -u user On startup, switch to run as user instead of the starting user. Applies only when started as root (as is normal when listening on port 25). --limit-connections limit, -c limit Accept at most limit simultaneous connections. Inbound connections beyondthis limit will be deferred or refused. --max-from-ip limit, -m limit Accept at most limit simultaneous connections from any given IP address; does not override --limit-connections, if set. --listen-address addr, -l addr Bind to the local address addr, instead of the default behavior of binding to all interfaces. Can be specified multiple times to bind to more than one interface or local address. --detach, -d Detach from the controlling terminal at startup, to run as a standalone daemon. See also --pid-file. --pid-file filename Upon startup, and after daemonizing if applicable, write the process ID to filename, for use by sysvinit control scripts or similar utilities. AUTHOR
