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...

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. That is its flexible and extensible as long as you know how to configure Dovecot which most OSX Server Administrators are not. I had a conversation with a co-worker not too long ago about being an OSX Server Administrator and I joked that Apple made great hardware and a great OS but most if not all of the services under the hood for Web, Mail,...

10.6.8 Server high CPU usage, hwmond culprit

It seems no matter how careful Apple is each OS update (especially server updates) reveals its own challenges for the user, that leaves them wishing that they had not left their stable platform for the bug fixes that made that update so desirable. the 10.6.8 server update was no different it claimed to fix such long time bugs as Server Side Rules which has been a thorn in the side of OSX Server Administrators everywhere who use OSX Servers as their primary email server. So many of us including myself,...

OSX Server Mailman Tricks

We have been using XServes as our primary mail servers at my organization for about two years now, we upgraded from an older Linux system and we could not be happier, since moving over to the 10.6 platform, we have enjoyed almost no email downtime, very easy to manage mail system and of course all the goodies that you would expect to run, some of which I have already mentioned (Squirrelmail) and also Mailman. Through my time configuring the server, migrating data and through other requests I have compiled a...

10.6.2 Mail Server draws a blank, subject?

So we upgraded from 10.5.8 Mail server to 10.6.2 and everything went very smoothly. Mailstores were migrated and the transition from Cyrus to Dovecot was great. However once all the email was moved over and all the settings were double, and triple checked. People started complaining that every once in a while their email was not getting through the server, it was getting bounced back to the sender. At first I thought that it was an internal issue with the users on our network, then I got a complaint from...

10.6.2 Dovecot Mail Backups

Before migrating to 10.6 Server we were running our entire mailstore on the 10.5.8 platform. Say what you will about Leopard, once we had it set up correctly it ran fine. We migrated because of the greater benefits of Dovecot over Cyrus. Many of the other features intriqued us as well such as the improved Wiki server and iCal server. However we were really excited about Dovecots ability to repair itself basically doing away with the need to ever have to rebuild a users mailbox. The one great thing about...

10.6.2 Squirrelmail, LDAP & Sieve

Snow Leopard 10.6 comes with built in Server Side rules (Sieve) that helps you to organize mail, if your like me and am supremely disappointed at the lack of functionality then you will be happy to know that there are alternatives out there. Snow Leopard still ships with a copy of Squirrel mail for OSX it also ships with many cool plugins for squirrel mail already installed. Lets look at the alternative to the built in Sieve scripts that ship with 10.6 Snow Leopard server. To start with you must...

10.6.2 Roundcube & LDAP

So like many other organizations mine was finally fed up with Horde as a webmail system. They had used squirrel mail in the past and was unimpressed by the graphical interface but admitted that it while it lacked glamour it always did perform as they would have expected. Before I had started there their mail system was running on a Linux box using Plesk and running Horde as their primary webmail interface. Immediately I got them into an XServe running OSX mail since their entire organization consisted of Apple iMacs...

10.5.8 Server Upgrade : Mail

Recently I have undergone a massive change, we have decided at our organization to go with Snow Leopard server in place of our Leopard Servers. Knowing that this could be problematic to use Apples built in GUI for migrating data I decided to start with a 100% clean configured Snow Leopard server and slowly start to migrate items over to the new server. Our current Leopard Server was running an DNS, Open Directory Master, Mail, and Wiki Server services. I have decided to share my experience in migrating our mail...
