The patched sources of uw-imap 2007f support building against OpenSSL 1.1.0 or later.
However, TLSv1_client_method() and TLSv1_server_method() restricts uw-imap to TLSv1.0.
These APIs, along with explicitly versioned APIs like
TLSv1_1_*_method()andTLSv1_2_*_method()are deprecated in OpenSSL 1.1.0 or later. The replacements are unversioned API functions:TLS_client_method()andTLS_server_method()which support TLS version autonegotiation.This allows the PHP IMAP extension to work with IMAP servers that enforce TLSv1.2 or higher.
