Virtual Users And Domains With Postfix, Courier And MySQL (Ubuntu 6.06 LTS)

Virtual Users And Domains With Postfix, Courier And MySQL (Ubuntu 6.06 LTS)
This document describes how to install a mail server based on Postfix that is based on
virtual users and domains, i.e. users and domains that are in a MySQL database. I’ll also
demonstrate the installation and configuration of Courier (Courier-POP3, Courier-
IMAP), so that Courier can authenticate against the same MySQL database Postfix uses. The resulting Postfix server is capable of SMTP-AUTH and TLS and quota (quota is
not built into Postfix by default, I’ll show how to patch your Postfix appropriately).
Passwords are stored in encrypted form in the database (most documents I found were
dealing with plain text passwords which is a security risk).

Howto clear/Flush DNS Cache in Ubuntu
View original post
Some distributions run a caching nameserver in the background out of the box while some do not. To clear the cache if you have such a daemon running, simply restart the nscd service in ubuntu.
Why would you clear your cache?
Most DNS clients will cache the results of name resolution request to speed up multiple lookups to the same URL. Just think about how many requests are made to the same domain when visiting a single web page. Every file, image, style sheet, etc. that is on that page and served from the same domain requires a DNS lookup.
So if you have an invalid DNS entry cached on your local client you’ll need to flush it out of the cache so your client can do a new lookup and get the correct information. Or your other option is to wait until that DNS entry expires and the cache flushes it automatically… which typically takes about 24 hours.
In ubuntu if you want to flush DNS cache you need to restart nscd daemon
Install nscd using the following command
sudo aptitude install nscd
Flush DNS Cache in Ubuntu Using the following command
sudo /etc/init.d/nscd restart
