“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 was not an open relay so I asked these users, if they had indeed sent this many emails in one shot without any kind of unsubscribe link...
One such service is the topic today, Dovecot. Dovecot is integrated with Server Admin, Apples GUI Server Administration tool. You can set two different kind of notifications to trigger here, a quota notification that will send an email out when someone is over a certain percentage of email quota and an email warning them when they have gone over quota. In my experience it takes more than a couple emails to make a user clean up their inbox.
sudo launchctl unload /System/Library/LaunchDaemons/com.apple.hwmond.plist which initially threw an odd error, looked at the list of loaded items by running launchctl list on the server and noticed that it was gone. I restarted my XServe and sure enough it had loaded itself. Figuring that there must be something in the OS automatically loading this on each reboot I started searching ways to modify or disable hwmond on my server. In my case I needed to stop the high CPU usage so badly that I was willing to make the tradeoff, of...
1. Migrating Mailman data from one server to another. I had many problems making sure that mailing lists, users, and archives were preserved when moving from our old server to our new server. Here are the following things you must do in order to ensure that the lists are preserved.
Great, another strange Apple bug I thought until someone was able to forward me the bounced email to my personal email account. Further insight in the error showed that the message was getting bounced back due to a blank subject line. As you can see from the example below its due to a blank or empty subject heading. Yes, apparently Apple has added this as an actual “Feature”. You can turn this off however by commenting out the only line of code in the file /etc/postfix/custom_header_checks.
The one great thing about 10.5.8 was the development of Mailbfr this was an amazing script that would help you backup your entire mailstore, recover email accounts, repair quotas, and of course rebuild or repair the entire mail-store. This was an invaluable tool, however since switching we have had to come up with our own solution.
To start with you must enable Sieve on your server to do this, start Server Admin, Mail > Settings > Advanced: Tick “PLAIN” on IMAP/POP and save it. Mail > Settings > Filters: Tick “Enable Server Side mail rules”, save it and restart the mail service. once your done here you will be able to use the built in web based interface for handling server side rules. However you can also install your own!
I found Roundcube to be extremely easy to setup, however sort of hard to configure and tweak for use on an OSX Server. The biggest drawback to the old mail system was that while everyone had email accounts they were local accounts meaning their was no LDAP database at work so there was no way to have an auto complete or global LDAP address book that most of the people at our organization really craved. I decided that when moving to 10.6.2 we would have to get this feature established...
setup the 10.6.2 Snow Leopard server clean before I did anything I setup DNS on the server and manually retyped and rechecked all of the DNS records from the 10.5 server to the 10.6.2 server. Once I verified that the DNS records were set. I checked the server’s DNS by running sudo changeip -checkhostname and it came back clean. Great good to go, or so I thought.
