Untrained Spamfilter Blues
I migrated my mailserver a few hours ago to a complete new system to have a better groupware solution and less noise. But honestly, I am already missing the old patchwork system as its spamfilter was working very very very… efficient. As the new anti spam system didn’t have that much training, the detection rate is simply crap.
Spam is different. Your spam differs from mine. So the filter needs some time to get used to the messages and learn. The result should improve over time quite well.

Groupware
April 5th, 2010 by Stargazer
As a system administrator there are many important things in my life I shouldn’t miss – one of them are my e-mails. They have grown as important as coffee for my life. Choosing the right e-mail solution is as important as the choice for the coffee machine.
But let’s be honest – simple mail isn’t always sufficient. In most cases we need to deal with contacts and schedules – in short, we are dependent on a groupware solutions.
The big issue about groupware is usually that they either cannot do the tasks I need (n)or kill my budget for home use as their licenses are for 25 users at minimum. Quite frustrating, huh?

eMail for Info-Junkies
February 6th, 2009 by Stargazer
There are many situations in which you might find it important to be up to date with your mailings – especially as soon as they hit your mailbox. This function is available with some mobile phones and commonly sold as ‘Blackberry functionality’ or push mail. In other words it is a more or less permanent connection between the mail server and the mobile phone which is now used by the mail server for pushing the messages across as soon as they arrive.

Moving mails to different servers
February 2nd, 2009 by Stargazer
Is it fate or simply bad karma that I’m always bothered with mailserver boxes? Or is it that they just cannot find anyone else crazy enough to even give it a try?
I’m not sure, but it’s me again, pushing mailboxes from one machine to another one. To make things right, I start doing things via imap and the good old toy ‘imapsync’, which just decided to discard about 90% of the messages showing the following error message:
flags from : [\Seen NonJunk]["02-Feb-2009 13:00:30 -0400"]
Error trying to append string: 58 NO APPEND Invalid flag list

A new MTA
January 19th, 2009 by Stargazer
I guess you all know the common problem with cheap hardware being used as a server box, don’t you? I’m fed up with those troubles and decided to use some professional hardware.

Slower delivery for a destination
May 19th, 2008 by Stargazer
Sometimes you have to slow down your mail delivery for some destinations or you might want to push out more mails for a certain server as it’s inside your LAN without being unkind to other people. Here’s a way of doing it:
The main.cf file of our postfix installation is the place where we define a new transport map and an according speed limit. As I am slowing down things here, the name of our test transport will be ‘snailmail’ – so here we go:

Groupware Patchwork
March 3rd, 2008 by Stargazer
Thinking back on my mail system here, I usually get that uncomfortable feeling in my stomach as the server structure was more or less some unordered patchwork which was started long time ago.
Everything started back when I still used SuSE Linux, way before YaST2 when the world was still fine and sendmail a great choice for smtp jobs. I was happy to get mails. Spam was not a problem those days.
