Email messaging#
Each member has an email box with a personal email address. The adress is composed of the login, followed by @club1.fr. For instance, the address of michel is michel@club1.fr.
Subaddresses#
In addition to the primary address, members have the option to use subaddresses. Subaddresses are like aliases. By default, they redirect to the primary address. All addresses of the form member+[...] @club1.fr are subaddresses of membre@club1.fr
For example, all emails sent to
michel+travail@club1.frwill be redirected tomichel@club1.fr.
These addresses may seem useless at first glance. But combined with automatic forwarding and automatic filters, they become very interesting.
Important
For automatic forwarding of a particular subaddress, a .formward+[...] file is used instead of the .forward file of the main address.
For example, to redirect only the address
michel+travail@club1.frit must be done in the file.forward+travail.

Web client#
A Web client provided by Roundcube is available at https://mail.club1.fr.
It allows you to manage and send emails as well as configure filters to automatically sort incoming emails.
But it also allows access to CLUB1 calendars and address-books synchronized with WebDAV.
Data storage#
All email data is stored as files in the mail folder of your personal space. This folder respects the Maildir standard, so it is possible to access it directly from an email client supporting this standard, for example after making a backup of the folder on a personal computer.
On the server, the CLI client Mutt is preconfigured to consult this folder by default. To use it, you must start by connecting in SSH to the CLUB1 server then run the following command:
mutt

Special folders#
The special folders use standard names, so they will be automatically recognized by the vast majority of email clients. In case they are not, here is the complete list:
INBOX: received messagesDrafts: drafts being writtenSent: sent messagesJunk: SPAMs (automatically deleted after 60 days)Trash: trash (automatically deleted after 60 days)Archive: archived messages
Quotas#
The mail folder is subject to a quota of 5 GB. This decision was made to encourage the deletion of old emails.
The maximum size of emails (received and sent) is 25 MB. If an email exceeds this size, it will be refused and the sender will be notified with the error message: Message size exceeds fixed limit or 552: 5.3.4 Error: message file too big.
Automatic forwarding#
It is possible to automatically forward the emails you receive to your CLUB1 address to one or more other addresses of your choice. To do this, you must create a file in your personal space that will tell Postfix to whom to forward your incoming mail. This file should be placed directly in your folder and be called .forward.
Warning
.forward is a hidden file.
Inside this file, all you have to do is list all the addresses to which you want to redirect the emails, separating them with a line break.
Example of .forward file forwarding to two email addresses:
perso@serveur.net
unautremail@cool.fr
Tip
It is even possible to keep your emails on your CLUB1 mailbox by adding your username to this list!
To end a redirection, simply delete the corresponding line. It is also possible to delete the file to cancel everything.

Automatic filters#
Sieve filters allow you to automatically sort the emails you receive. These filters are applied on the server side and therefore do not depend on any client. However, each user must configure them himself.
There are two ways to edit them. The easiest way is to use the CLUB1 Roundcube web client. It has a filter management interface in its settings.
The second method is to directly edit the filter file in your personal space:
~/.dovecot.sieve
