be happy when it works at all and use some proxy in localhost which handles the encryption over wire

here after upgrade to Fedora 28 the extension without even touchd it is enough that a graceful
reload leads in an endless loop of httpd crashes
sadly there is no useable replacement for my usecase testing mail servers for example if imap/pop3
deliver the same content since we had troubles of that sort in production and so tests exists with
php-imap

The problem is only concerning IMAP with StartTLS (port 143) and not direct SSL on IMAPS (port 993).
So IMAP with StartTLS can't use further than TLS1.0, and IMAP on SSL can use TLS1.2.

Description:
------------
It seems that the PHP IMAP module depends on some old library (libc-client2007e) that does not
support TLS v1.2. On imap_open() an error "TLS/SSL failure for <my_imap_server>: SSL
negotiation failed" is reported.
Please support recent TLS versions. This is also a security issue.
User report:
The IMAP server is running cyrus 2.5.
I had to modify the parameter tls_versions in /etc/imapd.conf from
tls_versions: tls1_2 to
tls_versions: tls1_0 tls1_1 tls1_2
to make the imapAccess work, which is less secure now.
Expected result:
----------------
IMAP connections with TLS v1.2 are working.
Actual result:
--------------
TLS/SSL failure for <my_imap_server>: SSL negotiation failed
