Thanks both for the useful pointers.

Adding an explicit keep does indeed set the header. I’m confused why it makes a difference though since the default implicit action is keep. I’m also surprised this is necessary given that the setflag directive of the imap4flags extension does not require an explicit keep. I can’t find anything in the Pigeonhole documentation or the edit headers RFC about requiring an explicit keep either.

Thanks for pointing out sieve-test, however, it doesn’t help clear up my confusion as it doesn’t mention the addheader directive at all:

sieve-test without explicit keep:

Performed actions:

(none)

Implicit keep:

• store message in folder: INBOX

sieve-test(root): Info: final result: success

sieve-test with explicit keep:

Performed actions:

• store message in folder: INBOX

Implicit keep:

(none)

In any case, adding keep has fixed my problem though - so thanks for the suggestion!

Hi all,

I want to add a custom header to incoming emails from a particular sender. This is what my user Sieve script looks like:

require “editheader”;

if address :is "From” “special-sender@example.com” { addheader “X-My-Custom-Header” “Header Value"; }

I have enabled the editheader extension in my Dovecot configuration:

plugin { … sieve_extensions = +editheader }

This doesn’t seem to work and no header is added to the email. However, if I also move the email to a different folder in the same if-block, the header gets added just fine:

require “editheader”; require “fileinto”;

if address :is "From” “special-sender@example.com” { addheader “X-My-Custom-Header” “Header Value”; fileinto “MyFolder”; }

Am I missing something?

Thanks Peter

Try 'sieve-test' utility to see what it is doing.

What version is this? Please provide output of dovecot -n.

This smells a lot like an age-old bug that was fixed long ago.

It works fine with master.

Stephan.
