listen_addresses ='*'

Otherwise, postgres will bind only to ‘localhost’ and won’t be accessible from your network. You will just get Connection Refused errors until you add this parameter to enable listening to TCP sockets. (That’s port 5432 if you look in /etc/services.)

NOTE: Webmin doesn’t give you a way to edit the parameters in postgresql.conf, you’ll have to do it manually.

The mechanism the spammers use is left over from the days before web interfaces.  Nowadays, your subscribers interact with Mailman almost exclusively via its HTTP interface.  Other than actual postings from subscribed members, and messages to the list owner, there is little or no reason to keep the vestigial email aliases.

To disable the vulnerable aliases:

With Virtualmin, go into the Webmin interface, under Servers; Postfix Mail Server; and click on the Aliases icon. You should see, for example, defined among the email addresses:

yourlist-example.com 	Program /usr/lib/mailman/mail/mailman post yourlist
yourlist-admin-example.com 	Program /usr/lib/mailman/mail/mailman admin yourlist
yourlist-bounces-example.com 	Program /usr/lib/mailman/mail/mailman bounces yourlist
yourlist-confirm-example.com 	Program /usr/lib/mailman/mail/mailman confirm yourlist
yourlist-join-example.com 	Program /usr/lib/mailman/mail/mailman join yourlist
yourlist-leave-example.com 	Program /usr/lib/mailman/mail/mailman leave yourlist
yourlist-owner-example.com 	Program /usr/lib/mailman/mail/mailman owner yourlist
yourlist-request-example.com 	Program /usr/lib/mailman/mail/mailman request yourlist
yourlist-subscribe-example.com 	Program /usr/lib/mailman/mail/mailman subscribe yourlist
yourlist-unsubscribe-example.com	Program /usr/lib/mailman/mail/mailman unsubscribe yourlist

for “yourlist@example.com” … I recommend you disable these aliases shown in bold above:

-admin-, -confirm-, -join-, -leave-, -request-, -subscribe-, -unsubscribe-.

You will want to do this for each mailing list on your system.

The default IP is 192.168.0.10 … in the Add Printer dialogs, choose Network Printer, then enter the IP address, the queue (default is: LP1) and choose the model.

The Device URI, when you are done, looks like:

lpd://192.168.0.10/LP1

Here’s the command to use:

find . -type d -exec chmod g+x "{}" \;

After years of frustration waiting for the Mozilla Thunderbird folks to add the ability to edit LDAP address-books, and years of frustration with the pigheadedness and brain-damagedness of LDAP server software, I decided to write my own little pseudo-LDAP server.

This is a proof of concept only and not meant for production use yet.

Here it is, in Perl: generic-ldap-0.1 It merely reads in

• a Thunderbird address book using a module from CPAN
• or an LDIF file, using another module from CPAN
• or anything else you care to write a plugin for (put it in the Plugins/ subdirectory)… there’s a start on a WordPress module, or you could write one for OSCommerce, or… the sky’s the limit

and shares that out via the LDAP protocol, using the Net::LDAP::Server module. Writing this meant seeing what the various email clients (Thunderbird, Evolution, KMail) actually wanted to see.

The nastiest, most brain-damaged part of LDAP is the non-standard field (attribute) names. None of these programs agree on what to call “home street address” versus “work street address,” for example.  What a nightmare.  My little server tries to remedy this by copying what it can suss out, into every possible field that your email client might be looking for.

What needs to be done yet?

• Better (or any) support for Outlook and Outlook Express, both reading their address-books and talking what they want to hear in terms of LDAP
• Security. Right now there isn’t much, beyond plaintext password authentication for each resource. You probably want to run this behind a firewall until there is support for TLS or SSL or something else. Perhaps another set of Plugins.
• Support for reading IMAP address books, vCards, etc.
• Support for more complex queries. Right now it only understands “OR” queries. Again, possibly as another set of Plugins.

This is written as an extensible system with Plugins. At the moment it fills my internal needs — specifically, sharing a single Thunderbird address-book inside an office.

Please contact me if you would like help adding features or additional development.
