Mail client configuration

You can use IMAP4 or POP3 protocol for incoming mail. We recommend to use IMAP4 because messages are kept on the server and we can access it from all over the world using Webmail client.

• login: my@example.com
• host: mail1.rootnode.net

Notice that your login is with @ sign. Some clients will display my@example.com@mail1.rootnode.net and it is completely normal.

Port numbers

Port number depends on protocol and encryption.

Protocol	Encryption	Port
IMAP	TLS	143
IMAP	SSL	993
POP3	TLS	110
POP3	TLS	995
SMTP	TLS	25
SMTP	SSL	465

Pine and Mutt

You can use pine and mutt mail clients from the shell server connecting via IMAP.

Webmail

There are two webmail clients available:

• Roundcube Mail https://webmail.rootnode.net/roundcube
• Horde IMP (traditional), DIMP (dynamic), MIMP (minimal) https://webmail.rootnode.net/horde

Sieve filtering

You can filter your mailbox using sieve language and managesieve protocol to put sieve rules on the server. Managesieve is supported by Webmail and many mail clients e.g. Mozilla Thunderbird. Some example rules you can find below. For detailed information about sieve look at http://sieve.info

Moving messages

With simple rule we can move incoming mails from Rootnode mailing list to appropriate directory:

require "fileinto";

if address :is "To" "users-pl@lists.rootnode.net" {
   fileinto "Rootnode";
}

Big messages

If you want to filter big message you can use:

require "fileinto";

if size :over 200K {
   fileinto "RootnodeBig";
}

to move them into seperate folder. You can even reject very big messages:

require "reject";

if size :over 5000K {
   reject "Sorry, your message is too big";
}

Vacation

From time to time everyone deserves some vacation:

require "vacation";

vacation :days 10
  :addresses    ["my@example.com","my@example.org"]
  :subject "Out of office"
  "I am not available at the moment.";

Spam

Rootnode has multi level spam protection. Before message is scanned by antispam and antivirus software there are RBL, HELO, SPF, greylisting and other checks. In most cases you will not see any spam message.

Spam filter must be teached in order to classify spam correctly. If there is a spam message in your INBOX:

1. Create special directory called Spam at the top-level, not inside INBOX folder.
2. Put spam message into this folder.

By doing it you will teach spam filter that message is a spam. If you are taking message back from Spam folder you are teaching spam filter that message is legitimate and should not be considered as spam anymore.

Every message has a special header X-DSPAM-Result. If it was classified as spam it will look like:

X-DSPAM-Result: Spam

You can set sieve filtering to put spam messages into Spam folder automatically. Here is example: http://sourceforge.net/apps/mediawiki/dspam/index.php?title=Filter_results_with_Dovecot_Sieve

It is very important to avoid spam. Try to not put your e-mail address in a way it can be crawled by spammers. If you are registering somewhere consider using one-time e-mail addresses like http://mailinator.com.
