    $ printf '%X\n' 336236705
    140A90A1


which breaks-down to library == 0x14 == 20, function == 0x0A9 == 169,
reason == 0x0A1 == 161.

    $ grep 'ERR_LIB_.*20$' crypto/err/*.h
    #define ERR_LIB_SSL             20


    $ grep 'SSL_F_.*169$' ssl/ssh.h
    #define SSL_F_SSL_CTX_NEW                              169


    $ grep 'SSL_R_.*161$' ssl/ssl.h
    #define SSL_R_LIBRARY_HAS_NO_CIPHERS                   161


I am guessing this means that SSL_library_init() (aka
OpenSSL_add_ssl_algorithms()) has not yet been called, and the
PQinitOpenSSL() function with (0,0) as arguments expects that OpenSSL
has been initialized by the application.

So perhaps Exim only initializes OpenSSL as needed (first SMTP use
of TLS, ...) but uses Postgres before that.
