Adding Diskspace

Tue, 28 Sep 2010 08:55:58 +0000

Sooner or later, you will most likely run out of disk space and you will want to extend the disk, either by adding a physical disk or by adding more disk space to a VMware installation. Both are fairly easy to deal with. When the disk gets added, it will show up in the server as either sdN (SCSI) or wdN (IDE) where N is the disk number where the first disk is 0, then 1, then 2, and so on. Please type the following on the command line to see all physically installed disks

Antivirus / Antispam techniques

Thu, 26 Feb 2009 09:59:14 +0000

[Antispam Architecture] The following steps is taken inside the mailserver before any mail is accepted for delivery: * An optional Greylisting will determine that the sending mailserver is a “proper” mailserver. * Postfix will make a conformance check on the mail headers to make sure that the send email address make sense * Postfix will use DNS to check that the sender domain exists * Postfix checks against a couple of Realtime Blocklist Lists (RBL) for known spammer domains and ip ad…

Using the Mailserver as a Mail Gateway

Wed, 13 Apr 2011 10:32:47 +0000

First - the Mailserver is ... a mail server. It was never designed as a mail gateway and except for that it works and does a very good job of keeping spam at bay, nothing will be made in order to make this more in to a mail gateway than it already is, so all the limitations of using the mailserver as a mail gateway is likely always going to be there. It might be that a separate mail gateway product will be released in the future that addresses these shortcomings.

Greylisting

Sun, 27 Dec 2009 05:18:14 +0000

Greylisting is a very effective method of reducing spam and malware. It works by initially refusing connections to the mailserver for a new server for 30 minutes, exploiting the fact that almost all spammers don't use proper mail servers and cannot properly handling resending of messages. The drawback is that emails from unknown mail servers will be delayed by 30 minutes. The mailserver tries to limit this delay as much as possible. Greylisting is enabled on default in the Mailserver. The defaul…
