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!
