RE: dovecot Digest, Vol 173, Issue 28 (INTERNAL)
Hi,
It is quite easy.
I use a client (thunderbird or windows live mail) set it up to use starttls on standard port 110. Logon and just do a list on the mailbox. The fatal error occurred when I logoff.

Hi!
I tried to reproduce this problem with dovecot-2.2.32 and OpenSSL 1.0.1k and was not able to. I enabled -DREF_CHECK on OpenSSL, but to no avail, the process did not crash. Is there something else you've done?

Hi,
Pop3-login are CORE-dumping when I log on with TLSSTART, I believe the same will happen with imap-logon to, but I have not tested it yet. The TLS session is coming up and it works fine until I log off, then it's core dump. Open sslvesrion is openssl-1.0.2k. We ran dovecot-2.2.27 before we upgraded to dovecote-2.2.32, and that seems to work fine. (not core dumping)

Hi! Just so you know, autocreate/autosubscribe is deprecated, you should use
namespace { mailbox INBOX { auto = subscribe } }
can you run
doveadm user administrator@email.dom
to verify that mail_home gets set correctly?

Yes, because it's a dumb IMAP server, which doesn't implement a lot of things, like SEARCH, FETCH BODYSTRUCTURE and similar. Dovecot is used as a smart proxy, which makes it possible to use it as a fully featured IMAP server.

Can you outline the exact steps you perform to get this?

Hi,
I switched back to 2.2.27 with the same config that I am using for 2.2.32 and it work fine.

How could I proceed? Any clue? It is quite annoying to see this entry in the log for each session.

Hi!
I tried to reproduce this problem with dovecot-2.2.32 and OpenSSL 1.0.1k and was not able to. I enabled -DREF_CHECK on OpenSSL, but to no avail, the process did not crash. Is there something else you've done?

I assume you mean STARTTLS. Can you provide gdb /path/to/bin /path/to/core and provide output of bt full?

Hi,
Pop3-login are CORE-dumping when I log on with TLSSTART, I believe the same will happen with imap-logon to, but I have not tested it yet. The TLS session is coming up and it works fine until I log off, then it's core dump. Open sslvesrion is openssl-1.0.2k. We ran dovecot-2.2.27 before we upgraded to dovecote-2.2.32, and that seems to work fine. (not core dumping)

Hi! Just so you know, autocreate/autosubscribe is deprecated, you should use
namespace { mailbox INBOX { auto = subscribe } }
can you run
doveadm user administrator@email.dom
to verify that mail_home gets set correctly?

Yes, because it's a dumb IMAP server, which doesn't implement a lot of things, like SEARCH, FETCH BODYSTRUCTURE and similar. Dovecot is used as a smart proxy, which makes it possible to use it as a fully featured IMAP server.
