POP3 and SMTP server for an ISP
Hi, I'm just started a great project of changing my mailing system due to some security and managing reasons. Right now I use exim+cucipop and my users added to /etc/passwd with shell /bin/false. Exim has been configured for supporting virtual domains and what's more it only delivers any message, if an alias is added to the user (so adding a user simply makes no affect). First I planned to keep on using exim with expanding the managing funtctions by integrating MySQL, but because of some security reasons I give it up. So by now I'm thinking about the installation of qmail+MySQL. The usage of MySQL would extremly important for me, actually I tried to find an MTA supporting MySQL. Would anybody so kind to give me advises about creating a mail system (pop3+smtp) hopefully based on MySQL? I'd so graceful if you only say something about your mailing system (if you have 4-5000 users), that's no problem if you have no MySQL. Thanks, Mihaly Litzler

now actually looking at lpd:), it doesn't seem to support being run
from inetd. you have several ways to go, though. first, trust it's own
builtin access control (lpd.perms or something); (possibly
additionally) put a packet filter in front of it; or you can add
libwrap support to lpd (it's not supposed to be hard); or the last
thing i can think of is to modify lpd in a way when it allows to be
run from inetd (that is, it takes its input from stdin, iirc)
having a very quick look at lpd.perms(5) i'd say its basically
equivalent (functionality-wise) to hosts.{allow,deny}, but also has
print service-specific options. i didn't find the equivalent option to
UKNOWN and PARANOID, though, but, as printing is supposed (imho) be a
`local' service, you have to maintain a consistent dns database and
you won't even need this.

I have lpd running on a publically-available server. Currently, it is secured with just /etc/hosts.lpd. I have seen an lpd that I can run with a "-i" switch to use via inetd. But it looks like the lpd from Debian (lpr 0.48-1) doesn't have this option. (I am interested in running via inetd so I can use tcpd access controls.)

The real advantage I see it with Maildir, is that it allows you to run your mailspool over NFS, as it require no locking. That enables you to have several different machines delivering to the same mailspool. NFS is of course slower but having several machines acting as your mail system gives you totally different possibilities of taking down one server and refit it while the customers dont notice a thing. The mailbox format is the 'defacto' standard and some claim it to be faster. But it requires locking if you use several different programs working with it at the same time. pam makes authentication 'transparent' in that it allows you to choose the authentication method separate from the program using it. If the mail program supports MySQL authentication directly, they usually also allow extra information to be pulled from the tables. Courier-IMAP is of that kind, and allows you to specify for each 'user' the uid,gid,mailbox placing, password etc. In the end that can give you a system where you dont need to give mailusers "real" unix accounts. /Roger Abrahamsson

Unfortunately Courier can't authenticate with OpenLDAP 2 (only 1). So, now I'm wondering if someone has used Courier IMAP with authentication through OpenLDAP 2 and if so, if the patch or extra module is or can be made available?

Re: pop3 and Maildir
I've been following this thread with interest because I'm also looking for a pop3 server for a Debian system . Anyway. There are some basic points I'm missing though. What are the pros and cons of Maildir versus other formats. What is the point with Mysql and pam authentication and how does it affect a mail server. Can somebody, please give me some pointers where those are explained, and what are the best current practices for setting up a pop/imap mail server? Thanks to all, Eric.

The real advantage I see it with Maildir, is that it allows you to run your mailspool over NFS, as it require no locking. That enables you to have several different machines delivering to the same mailspool. NFS is of course slower but having several machines acting as your mail system gives you totally different possibilities of taking down one server and refit it while the customers dont notice a thing. The mailbox format is the 'defacto' standard and some claim it to be faster. But it requires locking if you use several different programs working with it at the same time. pam makes authentication 'transparent' in that it allows you to choose the authentication method separate from the program using it. If the mail program supports MySQL authentication directly, they usually also allow extra information to be pulled from the tables. Courier-IMAP is of that kind, and allows you to specify for each 'user' the uid,gid,mailbox placing, password etc. In the end that can give you a system where you dont need to give mailusers "real" unix accounts. /Roger Abrahamsson -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".

However, our problem is that we want to use LDAP for authetication and we have to use OpenLDAP 2 (LDAP v3) because of the rest of the system. Unfortunately Courier can't authenticate with OpenLDAP 2 (only 1). So, now I'm wondering if someone has used Courier IMAP with authentication through OpenLDAP 2 and if so, if the patch or extra module is or can be made available?
