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)

Do you have an example e-mail that triggers the problem and the sieve scripts that are involved for the recipient that causes the crash?

That looks a bit like https://www.mail-archive.com/dovecot@dovecot.org/msg72690.html

Indeed. But I'd like to make sure this is the same problem.

Regards,

Stephan.

Seems to be. There is a =?iso-8859-1?Q?s=2Ev=F6gele=40XXXXX=2Ede?= <s.vögele@XXXXX.de> within the "To"-header, together with the line not address :all :comparator "i;octet" :contains "To" "robocup" in my global sieve_before script seems to trigger it

Fucking german umlaut.....

Fucking german umlaut..... Yep, that's the one. But ... hasn't this particular error already been fixed?

No, this is a different manifestation of the same problem.

Regards,

Stephan.

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@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.
