Learn about sieve syntax and how recipes are set up. This article is not a comprehensive list of everything that sieve can do, but rather a guide to helping you get started with sieve. If you want more information about what sieve is, see our article <\/span>What is Sieve Filtering<\/a>?<\/span><\/p>\n

Syntax<\/h3>\n

Below is the basic format of a sieve script. Depending on your chosen email client you may need to know the syntax in order to write your own sieve rules. <\/span><\/p>\n

Sieve uses <\/span>if<\/span><\/i> statements to test the email. If the condition following the <\/span>if<\/span><\/em> is not met, then the email will move on to the next statement or, if there are no more statements, go to the inbox. <\/span><\/p>\n

if <condition> {<\/span>\n<action>; <\/span>\n<action>; <\/span>\n...<\/span>\n}<\/span><\/pre>\n
Sieve also uses <\/span>else if<\/span><\/i> statements so that you can test multiple conditions in a succession if the first statement is not met. <\/span><\/p>\n
if <condition> {<\/span>\n<action>; <\/span>\n<action>; <\/span>\n...<\/span>\n}<\/span>\n\nelse if <condition> {<\/span>\n<action>;<\/span>\n...<\/span>\n}<\/span>\n\nelse {<\/span>\n<action>;<\/span>\n}<\/span><\/pre>\n
The <\/span><condition><\/span> specifies the part of the email that should be tested and what it should be tested for.<\/span><\/p>\n
The <action> indicates what to do with the email if it meets the requirements. For example, you might redirect the email.<\/span><\/p>\n
Common Recipes<\/h3>\n
If you want to use sieve to help filter your email, you can use these basic recipes to help you get started.<\/span><\/p>\n
Automatically Delete Mail from a Specific Address<\/h4>\n
If you want to automatically delete mail from an address, you can do so. Here is an example of what the command may look like:<\/span><\/p>\n
if address :is \u201cFrom\u201d \u201cbad@example.com\u201d {<\/span>\ndiscard;<\/span>\nstop;<\/span>\n}<\/span><\/pre>\n
By using <\/span>address <\/span>and<\/span> \u201cFrom\u201d<\/span>, the command will search incoming email\u2019s <\/span>From<\/span><\/i> address to see if it matches the contents of the second quotations. In this case, the contents is <\/span>bad@example.com<\/span><\/i>. If the <\/span>From<\/span><\/i> address matches <\/span>bad@example.com<\/span><\/i>, then the <\/span>discard <\/span>action will run. The <\/span>discard<\/span> action immediately deletes the email, keeping it from landing in your inbox.<\/span><\/p>\n
Redirecting Mail Based on Subject Line<\/h4>\n
If you want to redirect mail based on words in the subject line, the command will look like the following:<\/span><\/p>\n
if header :contains \u201csubject\u201d \u201chelp\u201d {<\/span>\n\nredirect \u201c<\/span>support@example.com<\/span><\/a>\u201d;<\/span><\/span>\n\nstop;<\/span>\n\n}<\/span><\/pre>\n
By using <\/span>header<\/span> in the conditional statement, the command checks the entire email header. By using \u201csubject,\u201d we narrow down the results to only the subject line. After that, we establish the word we are looking for in the subject line: \u201chelp.\u201d <\/span><\/p>\n
If the conditions of the rule are met, then the action will be executed. In this case, if the subject line contains the word \u201chelp\u201d, then the email will be redirected to <\/span>support@example.com<\/span><\/i>. <\/span><\/p>\n
If you want to search for multiple words in the subject line, you can do so by adding brackets around the words that could be found in the subject line.<\/span><\/p>\n
if header :contains \u201csubject\u201d [ \u201chelp\u201d, \u201cassistance\u201d, \u201cproblem\u201d] {<\/span>\nredirect \u201c<\/span>support@example.com<\/span><\/a>\u201d;<\/span>\nstop;<\/span>\n}<\/span><\/pre>\n
If any of the words listed within the brackets are found in the subject line, the email will be redirected. Only one word needs to be found in order for the command to execute.<\/span><\/p>\n
Combining More than One Condition<\/h4>\n
If you want to filter an email based on multiple conditions, you can. By using all of, you can list multiple conditions that the email must meet before the action is run. <\/span><\/p>\n
if allof ( address :is \u201cFrom\u201d \u201ccustomer@example.com\u201d, header :contains \u201csubject\u201d \u201corder\u201d ) {<\/span>\nfileinto \u201cSales Folder\u201d;<\/span>\nstop;<\/span>\n}<\/span><\/pre>\n
The example command above will check incoming mail to see if it is from the address <\/span>customer@example.com<\/span><\/i>. If it is, it will also see if it contains the word \u201corder\u201d in the subject line. If both these conditions are met, the email will be sent to the \u201cSales Folder.\u201d <\/span><\/p>\n","protected":false},"excerpt":{"rendered":"
