Hello,
I have a small Sieve script that tries to use vacation that segfaults.
The script is the one from http://wiki.dovecot.org/LDA/Sieve.
When I change the email address (I changed the local part into "skai"),
hence, vacation is skipped, the mail is delivered without any problem.
==== script start
require ["fileinto", "vacation"];
# Move spam to spam folder
if exists "X-Spam-Flag" {
fileinto "spam";
# Stop here so that we do not reply on spams
stop;
}
vacation
# Reply at most once a day to a same sender
:days 1
:subject "Out of office reply"
# List of allowed recipient addresses from auto reply should be sent.
:addresses ["ska at ux-2s11-9.inf.fh-bonn-rhein-sieg.de"]
"I'm out of office, please contact Joan Doe instead.
Best regards
John Doe";
