Sieve-Example:Move email to a suffix folder: Difference between revisions

<indicator name="Faults">[[File:Menu-emailadd.svg|link=Sieve_Filtering|30px|Back up to the sieve page]]</indicator>

...

me-ANYTHING@example.com

or the other way around, if you preferred:

ebay-me@example.com

amazon-me@example.com

...

ANYTHING-me@example.com

You also want this to be flexible and work as a 'catch-all' for any addresses you have as your suffix or prefix - you don't want to have to log in to the control page each time you want to create a new prefix/suffix.

(you can also use a '''+''' instead of a '''-''' if you wanted to - just alter the settings appropriately below)

#An alias - set on the Control Pages to - direct these extra addresses to your mailbox

#(optionally) A sieve filter - to magically sort these messages in to their own IMAP folder

[[File:Email alias for suffix.png|thumb|none|500|Alias]]

This sends messages addressed to me-ANYTHING@example.com to the me Mailbox

Optionally, you can magically move these messages in folders...

Once messages are being sent to your Inbox with the alias above, you can create a sieve filter to automatically move messages to their folder, if you've made the folder already.

<syntaxhighlight lang="sieve">

## Move messages sent to an address with a suffix eg, me-amazon@example.com in to a folder called Filtered/amazon, if it exists.

if header :regex "X-Delivered-To" "-([A-z0-9]+)@" {

set "suffix" "${1}";

stop;

}

*This filter uses the 'X-Delivered-To' header which is added by the A&A mail servers - even if you are BCC'd then the filtering will work. The X-Delivered-To is the 'envelope-to' header, which is the address the email was actually sent to by the sender (in lowercase).

*You'll need to add this sieve filter - eg by using the (latest) Thunderbird Sieve extension, see [https://support.aa.net.uk/Sieve_Filtering#Sieve_Server_Settings Sieve_Server_Settings] for info in the 'Creating Sieve Filters' section

*To add via Roundcube, select 'Actions', 'Edit filter set'.

===Variations===

You can create the folders automatically if you wanted add :create, - but some mail clients won't refresh their folder list until they are restarted, or the folder list collapsed and reopened. We also title case the new folder name - eg it will be called Amazon (capital A).

<syntaxhighlight lang="sieve">

set :upperfirst "suffix" "${1}";

fileinto :create "INBOX.Filtered.${suffix}";

</syntaxhighlight>

If you're using a + rather than a - to separate the suffix, then adjust the regex in the sieve filter above to be like:

<syntaxhighlight lang="sieve">

if header :regex "X-Delivered-To" "\\+([A-z0-9]+)@" {

</syntaxhighlight>

== Create the folders ==

So in your email program:

#Create a folder called: Filtered

#Create folders within Filtered for the suffix you want filtered there
