Modeemi membership includes an e-mail address in format username@modeemi.fi, and 1GB space for your messages (hopefully soon we increase that limit). Name.Surname@modeemi.fi alias is available upon request, and it is possible to use it as well during email submission. You can receive and send email with mail client of your choice - Thunderbird, or simply Gmail app for android.

If You are member of many aliases, You may like to send them to different folders in your mailbox, depending which alias mail was sent to. Sieve allow You to set up that kind of organizing mailbox - it catches the incoming messages, and depending on Your settings can put them in specific folder, or even do something else!

To configure sieve for your account, create file .dovecot.sieve in Your home directory (/home/username), and create config which looks like that (but adjust it so that it matches your needs). If You define that some mails are redirected to specific folder - first create it (You can do so in your mail client) - they are not automatically created by Sieve.
