Comment 4 for bug 1446633

I have a slight clarification. In my testing with php56u and your test code, I do get a time out:

$ time php ssl_bug.php
Connected to ssl://imap.ikmj.com:993
* OK ikmj-serwer.home.pl IdeaImapServer v0.80 ready
1 CAPABILITY
2 LOGOUT

real 0m30.737s
user 0m0.013s
sys 0m0.009s

I assume you will reach the time out if you wait long enough.

I have also discovered that your test script works fine when using a different IMAP server:

$ php ssl_bug_different_server.php
Connected to ssl://<redacted>:993
* OK [CAPABILITY IMAP4rev1 LITERAL+ SASL-IR LOGIN-REFERRALS ID ENABLE IDLE AUTH=PLAIN] Dovecot ready.
