Cyrus IMAP Server is case sensitive

From Mike at work:

Looks like Cyrus mail boxes have been case sensitive for some time:

From: http://asg.web.cmu.edu/cyrus/download/imapd/changes.html

Changes to the Cyrus IMAP Server Since Version 1.3

• Implemented the "reconstruct -m" command, for reconstructing the mailboxes file. IMPORTANT: it is necessary to run the command "reconstruct -m" as the cyrus user after upgrading the Cyrus IMAP software from version 1.3 or earlier. We recommend you make a backup copy of the mailboxes file in the configuration directory before performing the conversion.

• Mailbox names are now case sensitive, not case insensitive. "INBOX" is the exception, and is treated as being case-insensitive.

Here is what I found the fix to be. I added the following line to imapd.conf:

lmtp_downcase_rcpt: yes

postfix queue operations and tools

Tonight I found a utility called mailq (http://mail.python.org/pipermail/mailman-developers/2002-January/010542.html) (not quite the same as the mailq that comes with postfix). To remove the name conflict, I renamed this to mq and placed it in the /usr/local/bin directory. This utility can scan the postfix queue and report on the contents using a regex to filter the output by domain or e-mail address. Using mq with postcat (postcat -q `mq -i e-mail@domain.tld`) can be used to print the content of queued e-mails. The should be helpful for creating a web interface for monitoring the queue status. Also used with postsuper messages can be deleted (postsuper -d) or placed on hold (postsuper -h).

Use Open Source software to defend against spyware

Here's the idea:
Configure squid to block Internet access for Internet Explorer. Configure the firewall to require that all Internet web browsing go through squid. Looking at the squid documentation I see that the FAQ lists that ACLs can filter on the "User Agent" value from the browser. By blocking IE (and Outlook which uses IE to retrieve web content) from accessing all but approved sites, you could virtually eliminate adware / spyware issues from the network.

Good idea?

DocuWiki

DocuWiki combined with OOo appears to be an interesting set of tools for creating a documentation site.

Given that the Iannz DokuWiki macro works with OpenOffice.org, I would expect that it would also work with Star Office.

monthly tasks

Automate the reporting of secondary DNS hosting (example):
(echo "From: User@Domain"
echo "to: Billing@Domain"
echo "subject: list of domains for CustomerDomain"
echo ""
ll | grep CustomerDomain | awk '{printf "%s\n", $9}'
) | /var/qmail/bin/qmail-inject -fUser@Domain

Automate the reporting of e-mail hosting counts.
