Sieve vacation won't send second reply after timeout interval.

[David Williams]

Hi there


I'm having problems getting sieve to send a second vacation response.
For testing I've set sieve_vacation_min_period = 500s and the seconds
option in the script is 600. I send the first test message and get a
reply fine I then wait about 12 minutes send a second message and get no
reply. In the log I get "discarded duplicate response". I've restarted
dovecot and  removed the .dovecot.lda-dupes file before running the last
test. I'm using LMTP for delivery to Dovecot.

The sieve script is

require ["vacation-seconds"];
# rule:[Vacation]
if true
{
        vacation :seconds 600 :addresses "username at mydomain.com"
:subject "vacation" "test";
}

and doveconf -n is

# 2.2.19: /etc/dovecot/dovecot.conf
# Pigeonhole version 0.4.9 (357ac0a0e68b+)
# OS: Linux 3.18.12-gentoo x86_64 Gentoo Base System release 2.2 ext4

I've changed the identifying info to stop any spammers. Any ideas,
suggestions or just another pair of eyes telling me I've done something
stupid would be much appreciated.

Many thanks
