lmtp panic with many recipients

Hi,

I had an email with 58 recipients in the "To" and 13 in the
"CC"
Delivering it from exim to dovecot lmtp panics (see below)
Panic: file smtp-address.c: line 533 (smtp_address_write): assertion failed:
(smtp_char_is_qpair(*p))

# 2.3.1 (c5a5c0c82): /etc/dovecot/dovecot.conf
# Pigeonhole version 0.5.devel (61b47828)
# OS: Linux 2.6.32-696.23.1.el6.x86_64 x86_64 CentOS release 6.9 (Final)

Regards,
Olaf

That looks a bit like

Hi Stephan,

the original mail got stuck within exim on my production server and was from
"somebody" to many "somebodys" but not me.
So with exim I added as envelope recipient a test user "ms2test" on my
test system "irams2.ira.uka.de"
The test user "ms2test" has just an empty sieve script (all comments).
There is a global sieve_before-Script doing spam delivery into spambox:

#
require ["fileinto", "regex", "envelope"];
#
#
if allof (
         not header :comparator "i;ascii-casemap" :regex
"Subject" "fail.*deliver",
         not header :comparator "i;octet" :contains
"Subject" "DBWORLD",
         not header :comparator "i;octet" :contains
"List-Id" "ieft.org",
         not header :comparator "i;octet" :contains
"Subject" "Google Alert",
         not header :comparator "i;octet" :contains
"Subject" "Google Gaga",
  	not header :comparator "i;octet" :contains "Subject"
"foo",
         not header :comparator "i;octet" :contains
"Subject" "Woechentliche Spam-Benachrichtigung",
         not address :all :comparator "i;octet" :contains
"To" "robocup",
         not header :comparator "i;octet" :is "Envelope-to"
"ms2spam at ira.uka.de",

	exists [ "X-ATIS-Spam-Flag" ] ) {

		fileinto "INBOX.spambox";
		stop;
}

The mail in question contains third party adresses and content. So I can't
post it here.
I will try to reproduce it by myself with just dummy addresses.

Ok, another finding:
if I strip down the global sieve_before just to

require ["fileinto", "regex", "envelope"];
if allof (
         not address :all :comparator "i;octet" :contains
"To" "robocup"
	) {

		fileinto "INBOX.spambox";
		stop;
}
the mail got stuck.
If I reenable all other original lines, but remove the "rococup" line
the mail get's delivered.
