How To Install & Set Up Dovecot Mail Server With Sieve And Virtual Users
This document describes how to install the Dovecot mail server from source as an imap / pop3 mail server for your domain and how to set up the sieve plugin so your clients can use the sieve mail filtering language for their mail accounts.
Filtering PDF-/XLS-/Image-Spam With ClamAV (And ISPConfig) On Debian/Ubuntu
There is currently a lot of spam where the spam "information" is attached as .pdf or .xls files, sometime also hidden inside a .zip file. While these spam mails are not easy to catch with e.g. SpamAssassin or a Bayes filter, the ClamAV virus scanner can catch them easily when it is fed with the correct signatures as ClamAV is built to scan mail attachments.
Setting Up Postfix As A Backup MX
In this tutorial I will show how you can set up a Postfix mailserver as a backup mail exchanger for a domain so that it accepts mails for this domain in case the primary mail exchanger is down or unreachable, and passes the mails on to the primary MX once that one is up again.
Retrieving Emails From Remote Servers With getmail (Debian Etch)
Getmail is a program for retrieving emails from remote servers; it is very similar to fetchmail, but more flexible. For example, it can be configured to deliver mails directly to a Maildir or mbox mailbox without the need for an MTA such as Postfix, but of course it can also pipe the mails through an MTA if you want. Getmail can use so called filters such as SpamAssassin and ClamAV to scan the mails, and you can even tell getmail to delete mails on the original server only after a certain number of days.
Converting All Your MS Outlook PST Files To Maildir Format
One of the challenges you may face when converting an office from Microsoft Windows to Linux is that many people archive their e-mail in PST files. There are PST tools available, but most of them are commercial, since the PST file format is closed and protected by Microsoft. There are several non-commercial methods to achieve roughly the same goal, and in this tutorial we use IMAP (more specifically, courier-imap) to convert all our e-mails from PST to the Maildir format. The advantage of this approach is that you also lay the foundation for a new mail system, with all your old e-mails already imported the day you switch over.
Retrieving Emails From Remote Servers With fetchmail (Debian Etch)
Fetchmail is a program for retrieving emails from remote servers. Imagine you have five email accounts on five different servers. Of course, you don't want to connect to each of them to get your emails. This is where fetchmail comes into play. If you have a user account on a Linux server, you can make fetchmail download emails from remote servers and put them into just one mailbox (the one of your Linux user), from where you can retrieve them with your email client (e.g. Thunderbird or Outlook).
Importing Outlook Express Emails Into Thunderbird And Evolution
This tutorial shows how you can import Outlook Express emails, contacts, and account settings into Mozilla Thunderbird and Evolution. This is quite useful if you want to switch from Windows to Linux but don't want to lose your mails and address book. The procedure should be similar if you use Outlook instead of Outlook Express.
How To Install Zimbra Collaboration Suite (ZCS) On Ubuntu
This guide shows how to install the Zimbra Collaboration Suite (ZCS) on Ubuntu 6.10 (Edgy Eft) and 6.06 (Dapper Drake) server systems. Zimbra is a full-featured, open source collaboration suite - email, group calendaring, contacts, and web document management and authoring. It has a feature-rich AJAX web interface and is compatible with clients such as Microsoft Outlook, Apple Mail, and Novell Evolution so that mail, contacts, and calendar items can be synchronised from these to the ZCS server. It can also be synchronized to many mobile devices. ZCS makes use of many existing open source projects such as Postfix, MySQL, and OpenLDAP.
This document describes how to install a mail server based on sendmail that is capable of SMTP-AUTH and TLS. It should work (maybe with slight changes concerning paths etc.) on all *nix operating systems. I tested it on Debian Woody so far.
