Mail Hosting

What we can offer:

  • full hosting (MX1) on our servers:
    • multiple email addresses which can be real mailboxes or mere redirections at another third party addresses
    • based on milkypond.org (or maybe duckcorp.org) domain(s) or you own domain(s)
  • fallback retention (MX2) on our servers or, at your choice, partner servers (currently via Hivane)

Full Hosting

Access Methods

You can retrieve your mails, in case of a real mailbox, using:

  • IMAP+TLS (TCP 143) / IMAPS (TCP 993) on imap.duckcorp.org
  • or POP3+TLS (TCP 110) / POP3S (TCP 995) on pop.duckcorp.org
  • or one of the provided webmails

The IMAP protocol is recommended over POP3, as it provides many interresting features. If you want to download all your mails absolutely at home, loosing the ability to read your mail from anywhere on the planet, you can do that with IMAP too (look at your mail client settings).

You can use our servers to send mails out too via smtp.duckcorp.org using:

  • SMTP+TLS (TCP 25) / SMTPS (TCP 465)
  • and SASL authentication

Mail Filtering

With your favourite mail client, you can probably filter your mails in proper folders already. Nevertheless, this can be a annoying operation:

  • blocking you mail client for a long time if you have to process plenty of mails
  • downloading each mail information, and sometimes content (depending on your filters), is lenghty too, and cost much bandwidth
  • syncing filters accross your machines (home desktop, laptop, office machine…) is a pain in the ass
  • processing only when you're online prevents triggering actions in a timely manner (automatic redirect, vacation messages…), and running a machine 24/7 with a mail client polling new mails every 30s is not a solution

We provide a much better way to do this using the SIEVE filters. Shortly, SIEVE is a language dedicated to expressing mail filters. Our server is able to process your mails according to these filters as soon as they arrive. You then don't have to care about them anymore, and may use light mail clients or webmails when you're not on your machine with your favourite software. To push your filters on the server, a dedicated protocol exists: MANAGESIEVE (TCP 4190) on sieve.duckcorp.org

Several softwares support managing SIEVE rules:

  • Icedove/Thunderbird using the SIEVE extension (in xul-ext-sieve Debian package) provides a rules editor
  • Horde (Ingo) provides an easy to use web interface
  • Squirrelmail with the Avelsieve extension provides an easy to use web interface
  • Roundcube with an extension provides an easy to use web interface
  • sieve-connect provides a CLI to upload/download/activate your rules files

(tell us if you know more software supporting this feature)
