[Dovecot] redirect actions exceeds policy limit

[Mike Greene]

Hello,  We have a vacation/mail forwarder plugin in squirrel mail that allows customers to forward email.  It has come to my attention that there is a limit (appears to be 5) on the number of addresses that can be specified.  I'm now trying to track down where this policy limit is set.

This is the error we see in the customers .dovecot.sieve.log file:

main_script: line 26: error: number of redirect actions exceeds policy limit.
sieve: info: started log at Jul 25 07:02:54.

I checked the following for possible settings:

/usr/local/etc/dovecot/dovecot.conf
/usr/local/etc/sieve/dovecot.sieve
/usr/local/etc/sieve/global.sieve

I didn't see anything specific to limiting the number of redirects.  I'm wondering where else I can look to find where this limit is coming from and adjust it upwards.

We are using the following dovecot / pigeonhole versions.

dovecot-2.0.7
dovecot-pigeonhole-0.2.1
