Sieve e-mail filtering
We now offer Sieve e-mail filtering software on our mail servers. Sieve allows you to process incoming e-mail when it arrives in your Inbox on our server. This is great for anyone who uses a mail program (such as an iPhone) that doesn’t have its own filtering capabilities, or anyone who runs multiple mail programs and doesn’t like having duplicate copies of their filters. It’s also very useful because Sieve filters always run immediately on our server, rather than requiring your mail program to be always running.
If you are happy with the filtering rules available in your mail program (such as Thunderbird, Outlook, or Webmail), then you probably don’t need to use Sieve.
Sieve can let you setup some pretty sophisticated rules. For example, you could create a rule that says, “If an e-mail arrives in my work Inbox on a Saturday or Sunday from firstname.lastname@example.org, forward a copy to my home account, send a reply saying I’m too busy working and will reply on Monday, and then finally move the message into my Junk folder.”
Sieve can also be used to provide a common set of filters for all mailboxes in your domain.
Full details, including more examples, are available on our Sieve support page.
