In certain way it somehow belongs to all these places. As in addition to a home - it will need also a group of people who believe in it - the place where it lives should be easily accessible.

Re: [vchkpw] php vpopmail daemon etc. - developing story
I dont think implementing an independent tcp transport (even if its a very simple protocol) is a good idea nowdays. I would do it in a soap or xmlrpc wrappers, over an already well made, very lean, http server library. So then the clients could be made in any language without having to implement a client for the strange protocol we would be implementing. I dont think speed or network load is an issue here. I mean, i dont see deployments where a bit of latency in changing passwords, adding users...etc. would be an issue. If you have a 30 million users mailfarm, then your bw and iron is having a hard time in smtp or imap, really, a bit of extra traffic in thease kinds of transactions is not important.

The PostgreSQL team wanted it closer and we wanted it not so close. At the end they must focus on PostgreSQL and we - on pgaccess. If the main project gets into a difficult time (change of maintainers, etc.) - and if the sub-project is too close - it can suffer. At the end - the spirit of qmail is modularity - why shouldn't we continue it? I am not against - I just think we should be aware of the dangers of the thing getting stuck and killing a lot of investment in infrastructure and code that uses it.

X-Istence wrote: why? We could talk to it using normal sockets. I dont see why it would require a special API to talk to a normal deamon on a TCP/IP. Even Unix sockets. Here is my $0.02 on how to best implement a daemon... The daemon is in C [1] and runs under tcpserver. It opens a unix socket on the local machine, and/or a TCP port if we want to get into off machine access to the mail server. The deamon links to the vpopmail library, and makes calls to the library. The daemon MUST require all connections to be authenticated, preferably against the vpopmail user base. There isn't much use in a binary interface to the daemon, because almost all of the data it must pass is already ascii. I think about the only thing you could encode into a binary format is the identifier for which function you want to call. Domain names, user names, alias lines and everything else vpopail deals with is ASCII data, so that is the natural way to communicate with the daemon. I would suggest something like pop3: You send: It replies user rwidmer ok password mypassword ok addomain developersdesk.com mypassowrdok adduser [EMAIL PROTECTED] mypasswordok addalias [EMAIL PROTECTED] ok enter alias addr? [EMAIL PROTECTED]enter alias addr? [EMAIL PROTECTED] enter alias addr? [EMAIL PROTECTED] enter alias addr? [EMAIL PROTECTED] enter alias addr? [EMAIL PROTECTED]enter alias addr? ok list developersdesk.com minimaillist alias postmasteruser rick user ok list [EMAIL PROTECTED] [EMAIL PROTECTED] [EMAIL PROTECTED] [EMAIL PROTECTED] [EMAIL PROTECTED] [EMAIL PROTECTED] ok list inter7.com err - no such domain list [EMAIL PROTECTED] err - no such domain list [EMAIL PROTECTED] err - no such address exit ok Make it something that is conversational enough to telnet in to test the daemon without having to code both sides of the interface, and make sure . This syntax may not be exactly what it ends up using, but it should be close. Then you write a tidy little library in PHP, that uses sockets to open the daemon, and provides functions that make it look like you are accessing the vpopmail extension directly. I was hoping to report the list on sourceforge was up and running, but it seems to be taking a long time for my messages to be accepted. Even though I have already received the welcome message. Riok [1] Maybe it is my age showing, but it seems to me you want daemons lean and mean, and having to load the whole PHP interpreter just doesn't do it for me. (This is from someone who usually prefers to do everything in PHP.)

As i would want to deploy this over multiple servers, and having everything written out in normal ASCII would be a waste of bandwidth (all bytes count), i think that we should make it binary communication, just like DJB is trying to do with IM2000.

Efficiency is good, but you lose a lot of debugging ease when you go to binary protocols. How many times have you used telnet to debug pop and smtp sessions? Converting to binary communications does not save that much bandwidth at all, and for a large price of complexity. --Doug I have written apps to test certain stuff for me. Telnet on windows at the time was horrible, and would not work for what i wanted. But good point. X-Istence
