eMail for Info-Junkies
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.

MTA Blues
November 20th, 2006 by Stargazer
It’s not easy running your own IT things – but it’s easy to come in trouble with and waste hours. Trust me, I know that from my own experience, especially dealing with MTA systems. Here it is Postfix.
The number of mails rushing through my system is often more than 800 mails a day. The reason for such a high number may include spam traffic. To combat spam, I installed Spamassassin. If you do not want to waste hours searching for the reason why so many spam mails are not blocked, have a look at your firewall settings first. Spamassassin uses Razor, Pyzor, DCC and other distributed Services. If those ports are closed, no info from that systems may be gathered…
