I have added five email id in forward incoming mails. it gives error main script: line 8: error: number of redirect actions exceeds policy limit (5 > 4). I have increased the limit sieve_max_redirects = 10 in /etc/dovecot/conf.d/90-sieve.conf still it is giving an error.
ISPconfig's current dovecot setup does not use the files under /etc/dovecot/conf.d/, you need to make your change in /etc/dovecot/dovecot.conf instead (and also make your change to a conf-custom file so that future ispconfig updates don't overwrite it).
