sieve_max_script_size is ignored

Wed Aug 19 14:47:43 EEST 2020

I am in troubles with compiling sieve scripts larger than 1MB.

I see in logs following errors:

Aug 19 13:10:26 mail dovecot: lmtp(z.z at xxx.xxx)<22117><uNBGHKIIPV9lVgAA5ldI4A>: Error: sieve: autoreply: line 16818: quoted string started at line 3 is too long (longer than 1048576 bytes)
Aug 19 13:10:26 mail dovecot: lmtp(z.z at xxx.xxx)<22117><uNBGHKIIPV9lVgAA5ldI4A>: Error: sieve: autoreply: parse failed
Aug 19 13:10:26 mail dovecot: lmtp(z.z at xxx.xxx)<22117><uNBGHKIIPV9lVgAA5ldI4A>: Error: sieve: Failed to compile script `/var/vmail/xxx.xxx/z.z/sieve/autoreply.sieve'

I tried to set sieve_max_script_size = 2M or 0 (unlimited). I also tried to run "sievec -o sieve_max_script_size=2M /var/vmail/xxx.xxx/z.z/sieve/autoreply.sieve" but the result is still same. Below is my config.
Can you please advice where can be the problem?
