Here is the problem,

camel-http-stream.c:

static CamelStream *
http_connect (CamelHttpStream *http, CamelURL *url)
{
        CamelStream *stream = NULL;
        struct hostent *host;
        int errsave;

        if (!strcasecmp (url->protocol, "https")) {
#ifdef HAVE_SSL
                stream = camel_tcp_stream_ssl_new (http->session, url->host,
                					          ^^^^^^^^^								 
                 SSL_FLAGS);
#endif



and 

host = camel_gethostbyname (url->host, NULL);
                            ^^^^^^^^^
                            
These can't be utf8_hosts....

Currently the logic for determine the end of a valid url only considers ASCII 
character, suppose that you have a link in a received like follows

http://<multibyte host>/index.htm

within a mail, that link need to be active when viewed in mail window (should be 
clickable), currently 8bit characters are not treated as valid hostnames. This 
logic takes in each utf8 charcter of the hostname and will check whether each 
utf8 charcter is fit to be as a part of a hostname, each utf8 character will be 
converted to ASCII compatible encoding and will be checked.
