Re: lmtp panic with 2.3.16 (runnung ubuntu) and larger mails

2021-08-30 Thread Friedhelm Buescher


Hi,

i managed to "resolv" the Issue. i removed the sieve script - after that 
the issue was gone. Afterwards i replaced it with a new file with the 
same (!!) content (of course i had a backup on client-side) and it still 
worked. I created the new file same way as i did with the old (buggy) 
file - with the sieve-manager-plugin in thunderbird.


I have no clue whats going on.

regards,
Friedhelm

Could you please send gdb bt full?

Obtain core, see https://www.dovecot.org/bugreport-mail for information on how 
you might get that.

Then do `gdb /usr/lib/dovecot/lmtp /path/to/core` and issue `bt full`, and send

Seems to be. There is a
=?iso-8859-1?Q?s=2Ev=F6gele=40X=2Ede?= 
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.

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" "ms2s...@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.

Hmm, this could very well be a Sieve issue. Can you obtain a GDB 
backtrace for this problem (http://www.dovecot.org/bugreport.html)?


Can you reproduce it using the sieve-test tool with the involved Sieve 
script and some example e-mail?

I think the way I originally planned LMTP proxying to work is simply too
complex to work reliably, perhaps even if the code was bug-free. So
instead of reading+writing DATA at the same time, this patch changes the
DATA to be first read into memory or temp file, and then from there read
and sent to the LMTP backends:

http://hg.dovecot.org/dovecot-2.1/raw-rev/51d87deb5c26

The patch applies on top of v2.0 also. I tested that it appears to work,
but more testing wouldn't hurt to make sure it won't corrupt large mails
when sending them to multiple backends (one mail with multiple RCPT TOs
sent to multiple different backends)..

I believe there's too short LMTP_PROXY_DATA_INPUT_TIMEOUT_MSECS in
lmtp-proxy.c.

Re: [Dovecot] lmtp panic in proxy lmtp director

2011-12-05 Thread Dovecot-GDH

This happens when the LMTP proxy doesn't receive feedback from the back-end 
LMTP process for a certain amount of time.

This typically happens either because of very low I/O performance or NFS locks. 
Do an strace on your back-end LMTP processes. If you see that these processes 
are waiting on NFS locks ande you are using NFSv3, you should move over to 
NFSv4.
