[刘莹莹]

Hi dovecot
when I modify SIEVE_DEFAULT_MAX_REDIRECTS = 25 in sieve-file:dovecot-1.2-sieve-0.1.7/src/lib-sieve/sieve-limits.h 
I found this problem occurs about once a week,I'm not sure if it was caused by modify  SIEVE_DEFAULT_MAX_REDIRECTS = 25 , defaulte is SIEVE_DEFAULT_MAX_REDIRECTS = 4:
