Kerio mailserver, implemented.

OK, I’ve shown in the past how to set up an email server using DSPAM, Postfix, and MySQL. Well, it was becoming a lot to manage as domains and users grew. I decided to give Kerio a try. This has been one of the best moves I’ve done lately. This mail server was super easy to install and configure. It’s running on Fedora Core 4 and have been flawless. It handles multiple domains, forwarding, spam filtering, virus scanning, and much, much, more! To find out more about Kerio contact me. I’m a reseller and would love to give you more information about it.

Publish iCal calendars using a private server

I was wondering how I might be able to publish my iCal calendars so that my wife and I could share them. Well iCal gives you two ways to do this: Publish to .Mac or to a private server. I wanted to see if I could use the private server method. Turns out it’s really simple if you already have your own web server. The key is in turning WebDav on. I found this article (http://gentoo-wiki.com/HOWTO_WebDav) which worked it out perfectly for me. This is related to using gentoo Linux.

DSPAM, Postfix, and MySQL together on Linux

Wow, this was a fun task!
I’ve been considering an IronPort Spam and Virus Blocker Appliance
http://www.ironportstore.com/IronPort-SpamVirusBlocker.asp to protect myself from that annoying, time wasting, discussing problem of spam, but that appliance can be a little on the $$ side to someone like me. So, since I’m not ready to sink about $1,700.00 (initially) and about $300.00/year into defending my email I had to come up with a cheaper solution. I have for a while been using Spamassassin with postfix which has been OK up until the image spam showed up again, this has been a complete nightmare to deal with (hence the IronPort quest). So, in emailing a trusted fellowing Linux administrator, I was recommended DSPAM! And so the fun began…

Just some words about what type of setup I had to integrate with. I host multiple domains with multiple email addresses so I need to make sure I had support for virtual emails. So, this setup will support that, this way different users can decide what is considered spam to them and they’re not tweaking the entire system-wide spam filtering.

OK, so here’s the link to document I used to get my system going:

** CAUTION **
Do yourself a favor and go read them over before starting this project. Then come back and check out what pre-reqs were involved before being able to accomplish this task. I’m writing this after the fact so hopefully I’ll remember them all.
*************

Through the process I discovered the following pre-reqs were needed:

1. Make sure your postfix is compiled with a mysql dictionary, do ‘postconf -m’ as root to find out. If ‘mysql’ is not in your list then you’ll have to re-configure postfix and then do a ‘make upgrade’ in the source directory to get postfix to be able to use virtual email addresses.

2. Make sure your apache is compiled to handle SSL if you want to use the web interface – and you will want to, it’s pretty slick!
