[Dovecot] Dovecot deliver Segmentation fault when arrive the first message
Hi,
I have found this strange problem. I'm working with Debian 6, dovecot 2.1.9 and vpopmail-auth.
LDA is configured and works fine but the problem is when the first message arrive "dovecot-lda" return a "Segmentation fault", the message is written to the user's Mailbox but the message remains, also, in the queue of qmail (deferral: Segmentation_fault/) and at the second attempt is delivered fine.
If disable ACL (acl and imap_acl from mail_plugins) in dovecot.conf "Segmentation fault" go away. Moreover, without ACL at the first delivery folders like Sent, Drafts, Trash, Spam appear immediately.
An example,
new user:
root@demo-vpop ~ # tree /home/vpopmail/domains/qboxdns.it/cecchi2/Maildir/ -a /home/vpopmail/domains/qboxdns.it/cecchi2/Maildir/ ├── cur ├── maildirsize ├── new └── tmp
root@demo-vpop ~ # cat testmail.txt | /usr/local/dovecot-2.1/libexec/dovecot/deliver -d cecchi2@qboxdns.it Segmentation fault
root@demo-vpop ~ # echo $? 139

Hi Timo,
had you occasion to see the problem? Can I provide more information?
Thanks
After further testing I found this behavior, a note, I'm using dict quota in mysql.
add a new user
delivery the first email via deliver
"Segmentation fault"
I remove the newly created user
add the same user
delivery the first email via deliver
OK
add a new user
the user connects via pop/imap
delivery the first email via deliver
OK
add a new user
manually create the entry for dict quota <<==
delivery the first email via deliver
OK
it seems that if there is user's entry in the dict database the problem does not appear.

This backtrace is rather weird. Could you also do (instead of bt full):
fr 1 p *ns p *ns.user p *auser
It crashes because auser->dict = NULL, but it should never be NULL.

If first add a news user, than run quota recalc and after deliver the first message "deliver" not crash:
# vpopmail/bin/vadduser test10@qboxdns.it # doveadm quota recalc -u test110@qboxdns.it # cat /root/testmail.txt | /usr/local/dovecot-2.1/libexec/dovecot/deliver -d test10@qboxdns.it
When add a new user without quota recalc deliver crash:

Hope this will useful

This backtrace is rather weird. Could you also do (instead of bt full):
fr 1 p *ns p *ns.user p *auser
It crashes because auser->dict = NULL, but it should never be NULL.
