Stay off of blacklists: Limit postfix recipients

I have heard this story it seems over and over again, I also have been the topic of many email horror stories. They usually go like this “I just setup a new server and within days we were on a corporate email blacklist, I contacted the company in question and asked why are we on your blacklist, why won’t you deliver our email. They shared with me an email log of thousands of emails being sent from my mail server through several legitimate email accounts. I ensured that my server...

Installing MYSQL on OSX Lion Server

It is a fact that Apple has migrated itself away from MYSQL. It is also a fact that most people who continue to buy Apple Servers have been using MYSQL for some time and have websites or other content that sill relies on this technology.

On the contrary installing and configuring MYSQL to run on an OSX Lion server is moderately easy and gives greater insight as to how MYSQL...

Better Quota notifications for OSX Server

OSX Server comes pre-packaged with Dovecot one of the best IMAP services out there and one of the most extensible and flexible in my opinion.

Admins in the Government sector for example can only use sanctioned tools and or methods for dealing with common Server Admin...

Adobe Reader, Network Accounts & 10.6.8 Server

There has been a lingering issue with running Network Accounts and letting the users of those network accounts use Adobe Acrobat Reader on an OSX Leopard & Snow Leopard server environment for a while. The issue presents itself as a hard crash of Adobe Reader, while the user is trying to use the program. After much trial and investigation, I have narrowed down the reason for the crash to the fact that the program is trying to save temporary cache files to the users Documents folder. Since the folder is...

10.6.8 Installing SSL Certificates Correctly

I am well aware of how to install and setup SSL certificates in OSX Server but that was not always the case. I am writing this how to for those less experienced who may find this article helpful. There are two types of SSL certificates, that you can use on your OSX Server. Self Signed Certificates are ones that are created on the server and are not digitally verified by a third party service. You can use these certificates to encrypt or secure your servers services but you will ultimately...
