Hi,
I cannot reproduce any of this so far:
Maybe try again with log_debug=category=imap or category=sieve
And provide all config (`dovecot -n`) and the Sieve scripts involved.
Regards,
Stephan
Hi,
thanks for your reply. I changed log_debug and am waiting for the next
Panic.

These two are for rspamd and work for my user when using roundcube and
thunderbird on android..

require ["vnd.dovecot.pipe", "copy", "imapsieve", "environment",
"variables"];
if environment :matches "imap.user" "*" {
set "username" "${1}";
}
pipe :copy "learn-spam.sh" [ "${username}" ];
* report-ham.sieve:
require ["vnd.dovecot.pipe", "copy", "imapsieve", "environment",
"variables"];
if environment :matches "imap.mailbox" "*" {

}
if string "${mailbox}" "Trash" {
stop;
}
if environment :matches "imap.user" "*" {
set "username" "${1}";
}
pipe :copy "learn-ham.sh";
* I disabled this one during the time I posted the initial message. For
completeness:
#mailbox Trash {
# sieve_script flag-seen {
# type = before
# cause = copy append
# path = /srv/sieve/imapsieve/setflag-seen.sieve
# }
#}
* setflag-seen.sieve:
# set flag "\\seen"
require ["imap4flags"];
setflag "\\seen";
