The problem is that now when you login to Horde, the portal comes up
with an empty mail block (ie, no inbox display) BUT the block with
Newest Unseen Messages is fine. If you try to go to Imp to see your
email you are logged out with the onscreen error "IMAP error reported by
server."
IMAP access using other mail clients like Thunderbird and K9 on my phone
works fine.
I think the problem is somewhere in the new PHP 5.6.5, but so far I have
not been able to find any sort of smoking gun that points to exactly
which change is the problem.
Syslog in Horde debug mode reports the lines below for HORDE [imp] and
Cyrus. You can see the original login success for IMAP, then several
failures of 'listMailBoxes' as I navigated from the opening portal, to
the config to enable debug logging and back to the portal to click on
the Mail portal block and document the error. I only included the
relevant Cyrus & Horde log entries (there are a LOT of them) for the
initial login + failure and the debug failure.
FYI, the Cyrus "fetching user_deny.db entry for.." log entries are
normal. I am not a Cyrus guru so I am not sure why they are there, but
they have always been there before this issue started and are also there
when checking my IMAP email with Thunderbird or K9.

In summary: I think this is being caused by the PHP update yesterday.
Cyrus did not change and is working fine with other clients and Horde
did not change either. If anyone has any ideas about what I could check
for in PHP, it would be greatly appreciated.
I see where the error "IMAP error reported by server" is generated in
Horde/Imap/Client/Socket.php . But I have so far been unable to track
down a way to determine exactly what IMAP call is generating the error.
The error message indicates "listMailboxes" is the problem call, and the
logs indicate SSL/TLS negotiation and authentication is fine.
But when I manually connect to the IMAP server, I can list mailboxes
with no trouble as shown below.
openssl s_client -starttls imap -connect localhost:143
. OK Completed
a1 LOGIN andydor...@comehome.net mypassword
a1 OK [CAPABILITY IMAP4rev1 LITERAL+ ID ENABLE ACL RIGHTS=kxte QUOTA

I get the full list of all mailboxes
...
a2 OK Completed (0.002 secs 53 calls)
a3 EXAMINE INBOX
...
a3 OK [READ-ONLY] Completed
a4 LOGOUT
* BYE LOGOUT received
a4 OK Completed
So I am now trying to find exactly what command is being sent to Cyrus
to request the list of mailboxes to see if I can recreate the problem
with a manual tls imap connection.
