I don't think there will be any upstream modifications at least:

   SIEVE implementations MUST handle missing scripts being referenced
   via an includes in an existing script.  An error MUST be generated
   when a missing included script is descovered during execution.

Then again the include draft expired over a year ago.

Yeah, I did look.

I sure could patch something together. Before doing that, though, I 
hoped to be enlightened with an official way, so I would not have to 
drag around obscure modifications.


Probably the cron script is how it will end up.

create the personal sieves as empty files, but how would I best do that? 

I was thinking about a post-login script, but sieves can run before anybody 
logs in. Is there a way to wrap the deliver LDA, to have it create these 
files just as the first mail arrives?


You can do either of them, you can wrap the LDA easily with a bash script 
or a C programm, then exec() the LDA, but this will be done _each_ time a 
mail comes in. I don't like it.


How do you create your users? Would it be possible to add on some script, 
in order to prepare the users on the mail storage server? Or run a cron 
script once an hour to look for new users and create the files.

These are virtual users, so there is no /etc/skel to copy.

[Dovecot] Optional Sieve includes

[Anders]

I (think that I) want a global Sieve setup like this:

  require ["include"];
  include :global "spam.sieve";
  include :personal "folders.sieve";
  include :personal "vacation.sieve";

... that does not fail if a user has not created the personal filters. 
Any ideas how to do something like that?

I read the source, but it seems that a failed include will exit the
Sieve, so the above will not work.

Incidentally, I think I found a typo, so a patch is below.


Anders.
