Used to successfully shrink a Microsoft SQL 2000 database.

Note: I do not believe that I have to do all this, but it did work. It did not shrink the log using the DBCC commands below as expected. I will update as learn more, but needed to get this written down, since it did achieve what I had wanted (to reduce the size of the log).

From isql:
DBCC SHRINKFILE(dblogname, size)
DBCC SHRINKFILE(dblogname, size)

From MSSQL Enterprise manager:

for testing address rewriting and routing configurations.

SMTP Auth using saslauthd and IMAP authentication – Redhat/CentOS/Fedora

I used the following procedure to support SMTP Auth on a CentOS5 machine.

Created a name in my DNS to use for the outgoing mail server on remote mail clients. This will allow me to easilly migrate the service to another server or IP address.

Made the following modifications my /etc/postfix/ This configures postfix to support SMTP Auth.

vi /etc/postfix/

# JGZ 4/16/2008 – Begin – To enable SMTP Auth using dovecot (IMAP) authentication.
# Enable SASL Authentication
smtpd_sasl_auth_enable = yes

# Report Authenticated Username In Headers
smtpd_sasl_authenticated_header = yes

# Set Path for SASL Auth (this references the smtpd.conf file created earlier)
smtpd_sasl_path = smtpd

# Support Broken Microsoft Clients
broken_sasl_auth_clients = yes

# Enable on authenticated user to send
smtpd_recipient_restrictions = permit_sasl_authenticated, reject_unauth_destination
# JGZ 4/16/2008 – End – To enable SMTP Auth using dovecot (IMAP) authentication.

Reload postfix to implement the changes:
postfix reload

Made a backup copy of my /etc/sysconfig/saslauthd:
cp -p /etc/sysconfig/saslauthd /etc/sysconfig/saslauthd.orig

Modify /etc/sysconfig/saslauthd to support IMAP authentication and specify the remote IMAP server. Note: you can use a name or IP address. Furthermore, you can use is running the IMAP server on the same machine. I used a name to better accommodate changes I might need to make.
vi /etc/sysconfig/saslauthd

# JGZ 4/16/2008 – to authenicate via IMAP server

# JGZ 4/16/2008 – To send authentication request to remote server.

Start saslauthd.
service saslauthd start

Configure saslauthd to start at boot up via ntsysv.

This works well. It is very simple. While the IMAP password is transmitted twice to send and receive mail, the password is encrypted.
