Re: POP3 and SMTP server for an ISP
Hello again. I've been closely following this thread, and I was wondering what sort of system that would be recommendable for 50.000+ users? No local access and no home directories is wanted, but pure mass hosting. Maildirs I assume is essential. I've tried some programs, but they fail horribly when the system gets big. I have been wondering about file system limitations too. Say you have 5000 users in each subtree and they have between 100 and 30.000 emails in their folders. (The large figure is an example of a smartass like me. lol) Preferrable all user authentication is done in MySQL or other SQL server.

RADIUS accounting and block accounts
I am about to finally set up portslave to authenticate with RADIUS (so that it can be replaced by a NAS). Anyway the RADIUS authentication will backend to an LDAP database, but I was just wondering if it would be possible to backend the RADIUS accounting to a PostgreSQL database? Can anyone recommend a radius server that would support this (but it will be used exclusively for accounting, unless it supports LDAP and has a good license). This leads to the next question, I would like to be able to automatically disable accounts and disconnect them if they've used up more than allocated hours. So say they have a 20 hour block acount, when it gets up to 20 hours I would like to d/c them and disable logins untill the next month. Is this possible at all? Or is it going to require a bit of hacking and a few perl scripts? Thanks, -- Jeremy Lunn Melbourne, Australia -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble?

htaccess success!
Thanks to all who helped me solve this problem. It eventually transpired that I had not one, but FOUR almost identical docroot Directory directives in my configuration file(s) -- two containing AllowOverride None; one containing AllowOverride All; and one containing AllowOverride Authconfig. Obviously, I kept editing the wrong one. :| How they got there I have no idea. But I suspect a bit of 'mischievous' editing somewhere along the line, by person or persons unknown, with the aim of nullifying the authentication.

forwarding mail to internal mail server
What's the "preferred" method of forwarding all incoming mail from the gateway to an internal mail server? I have one box (Debian Woody, sendmail 8.9.3) currently mounting /var/mail from the internal mail server (also a Debian Woody box, running 8.9.3). This seems to work okay, but I'm just waiting for something to break. I've thought about setting up port forwarding so that anyone connecting to port 25 on the masquerading box is transparently forwarded to the internal mail server. That, however, is something I'd like to avoid. I'm open to any suggestions anyone may have. I've thought about using virtusertable on the gateway box to rewrite the addresses so as to be delivered to the internal mail server, but I'm not sure about this. Thanks. -jg -- Jeremy L.
