...port 993, which appears to let the connection initiate but then squashes and disconnects the socket during ssl handshaking. gdb backtrace and Activity Monitor's "Sample Process" show that imap-login is stuck calling ioloop-kqueue's io_loop_handler_run -> io_loop_call_io -> ssl_step repeatedly; dtruss shows that it is repeatedly making system calls to kevent and read, the latter returning -1 with errno 57=ENOTCONN="Socket is not connected". (I also tried ./configure --with-ioloop=poll and --with-iopoll=select instead of the default best = kqueue but the results were...

...This can be tested by disabling SSLv3 in the dovecot config (ssl_protocols = !SSLv2 !SSLv3) and trying to connect with openssl and forced sslv3 (openssl s_client -ssl3 -connect localhost:995). This would cause a crash. What was going on is this: In ssl-proxy-openssl.c in line 545 in the function ssl_step() the function ssl_handshake() is called. There SSL_accept() is called. If SSL_accept failes - because a client sent an invalid packet or something the server doesn't support or any other reason - ssl_handle_error() will be called. ssl_handle_error() will call ssl_proxy_destroy(). ssl_proxy_de...

We've been struggling with a problem for the past couple of days which to this point I've only gotten to be able to boil down to this: 1. Install nessus home edition (less pluggins I assume) 2. run all scans (sequentially or in parallel, doesn't seem to matter) 3. about 3 minutes in /var/log/messages will show segfaults on imap and/or pop3 imap-login[22185]: segfault at

Hi Timo, I've got some errors with pop3 proxying and dovecot 2.1.9 I's occured on the proxy side: Aug 7 13:16:47 dev1 dovecot: pop3-login: Fatal: master: service(pop3-login): child 23046 killed with signal 11 (core dumped) Server side shows no error, and runs the same dovecot version. Thanks for your help. Best regards Tonio Buonaguidi Core dump: GNU gdb (GDB) 7.4.1-debian
