Hi Stephan
We tried it again last week with the latest dovecot version and still
having the same issue. The whole setup works perfectly fine with the
latest version of dovecot 2.2
The problem only exists if the quota of the user is full, every other
message gets delivered without a problem, and the lmtp process change
back to READY state. But in this case, it stays in the "RCPT TO”
forever. I’ve talked to ‘cmouse’ today on the IRC and he recommended
continue here.
kdump and lmtp debug logs: https://pastebin.com/raw/MSVcj6qN & And
from the backend I only have a tcpdump from another process but it's
always the same behaviour: https://pastebin.com/tVj842Dq
If it doesn’t help, please let me know which logfiles exactly would
help and would make the difference ;)
Managed to reproduce it myself. We have a fix pending. Tracking this
issue internally as DOP-1956.
Regards,
Stephan.
Greetings Pascal

As you can see the process isn't shutdown and still in transaction as
long dovecot is running. It destroyed the transaction when I stopped
Dovecot. And this behavior only happens when the mailbox of user is
full...
Any Ideas how to debug this correctly?
The provided logs look incomplete. The reception of the RCPT command
by the server-side is not in the log, only the generation of the
response. Also much of the client-side activity is not in the logs.
Also, a raw log of the TCP protocol exchange between Dovecot and Exim
and also between proxy and backend can be useful. If the connections
are plaintext you can use wireshark or - if not - you can use the
Dovecot rawlog facilities.

So far, I haven't been able to reproduce anything weird at this end.
Can you provide:
- Output from `dovecot -n'
- Protocol logs from the connections between Exim and Dovecot
director/proxy and between Dovecot director/proxy and Dovecot backend
(e.g. using ngrep when connections are plaintext or using the rawlog
facility).
- Dovecot debug logs produced with `log_debug=category:lmtp' for both
director/proxy and backend

Stephan.
