Hello Stephan,

Preface - one of my users went to vacation and changed his sieve script to run autoreply vacation message, after that - I have noticed some annoying errors in system log, like:

dovecot-lda[2400]: segfault at 3eb3333f ip b7446c7a sp bfaab050 error 4 in libdovecot-sieve.so.0.0.0[b7429000+5b000]

Dovecot-error log is empty, but in exim log(exim runs dovecot-lda) I got:

2012-08-13 09:35:27 1T0oFK-0000aW-6j ** sr@domain.com (sr@domain.com, root@domain.com) F=59942270813@mymail.in.ua R=ldap_accept T=local_delivery: Child process of local_delivery transport (running command "/usr/libexec/dovecot/dovecot-lda -e -d $local_part@$domain") was terminated by signal 11 (Segmentation fault)

sr@domain.com - is the user, who created such sieve-script, which cause segfaults. I have tried run the same message over this script from sieve-test utility - but result is success.

Can you please, take a look to this sieve script and check is it ok, I'll send it to you privately since it contains user's data. Also I'll attach message.eml which triggers segfault.

Dovecot version - 2.0.21, Sieve version - 0.2.6. Relevant to sieve dovecot config section: plugin { sieve = ~/.dovecot.sieve sieve_after = /etc/dovecot/sieve/default-after.sieve sieve_dir = ~/sieve sieve_extensions = +notify +spamtest sieve_spamtest_max_value = 10 sieve_spamtest_status_header = X-Spam-Scan-Score sieve_spamtest_status_type = score }

Hope you'll help.
