Change to allow

[Sven Mueller]

Hi.

As some might know, I'm member of the cyrus-imapd packaging team in
Debian. We have closely tracked the 2.2 CVS branch, so we also
incorporated the changes made by murch on August 30th with the following
commit message:

added 'sieve_allowreferrals' option which controls whether timsieved
issues referrals (default) or proxies

However, as you can see from the bug report we got[1] and the exchange
following it (all on that web page), this badly interacts with at least
some murder setups. I'm actually unable to tell why it does so and don't
have the time to dive into the source to find out, but I wanted to let
you know.

Regards,
Sven
