Mail server installation EXIM4

Posted by Pablo Gonzalez on July 3 2012rd

Good afternoon, in this article we will see how to makeMail server installation EXIM4with a dynamic IP address.

Personally, I do not recommend this configuration because we have serious problems blocking blacklist, so, this article has only academic value. To inspire the reader to other servers and services.

We start from an installation of GNU / Debian default 6 in an old notebook.

Add repositories / Etc / apt / sources.list

deb http://ftp.fr.debian.org/debian/ squeeze main contrib non-free
deb-src http://ftp.fr.debian.org/debian/ squeeze main contrib non-free

rename with # the line that begins with deb cdrom.

We enter the following command with the username root:

aptitude update (With this update we have added the repositories above).

Install the no-ip client, since I have dynamic ip address and in many cases (the vast majority) must match the domain to your ip when mail is delivered, otherwise, the target server will consider it as spam. I assume that you generate a suitable account if necessary.

We can decompress with xvzf tar noip-duc-linux.tar.gz and we will create a folder.

We continue with the following commands:

cd-2.1.9-1 noip

make install noip2.c

We requested email address, password and the update interval, which in my case I have considered going down to 5. We also ask if you want to run any programs in each update, and in my case I select No.

We generated the configuration file non-ip2.conf. Megacrack read »

Solve problems Outlook and Exchange Performance

Posted by Xaus Xavier Nadal 10th on May 2012

Good Morning.

For some years that Outlook users with Exchange 2003 are experiencing slow systems, time out, errors, etc .. Each day the amount of mail we receive is higher, the size of e is higher and capabilities of servers they remain the same (subject crisis).

But the mistake that the mail server is responsible, is a wrong way to take on the problem.

Outlook 2003 / 2007 / 2010 like many other mail systems have their limitations and best practices that should follow strictly and only without modifying the Outlook system users and especially without investing in new hardware or even without thinking about upgrading your system mail to a recent version we could achieve very good results in performance mail system is concerned. (The user will thank you.)

One of the major problems and very easy to solve is the number of emails in each folder in Outlook.

This number post should never exceed 3000 post (Sounds like a lot at first, but look at your inbox or sent items folder (How many have ???).

With this simple change we can see a substantial improvement in the performance of our Outlook and therefore in the user feedback regarding the mail system. And if you look also amazing on the Exchange server load.

The contents of each folder is stored in a table in the Information Store Database, as it increases the number of items in each folder mechanism Extensible Storage also called ESE using data structures B + trees to store records also increases and as the number of records increases, the number of I / O disk to store new information also increases and decreases the performance of the entire system.

Delete e-mails sent with Outlook

Posted by jl on September 29 2011th

Hello everyone

Who has not happened once we're writing an email to send and we give we are wrong and some of the recipients to whom it should not be sent in hard copy, or we have not crept into the content.

At the user level, Exchange has an option so that they can remove (they call retrieve) whenever the user that have sent the mail is logged on and has not read or moved from the Inbox, and of course sow we are within the same Exchange.

To do this you must go into the Outlook client mail we sent in the tray sent items, open it, and on the Actions menu select retrieve message and the following window will appear with the different choices we can make. The first is that we would eliminate the mail.

We could also replace the mail with a new message

 

 

 

 

 

 

 

 

 

Until next time

a greeting
