New function...back from the depths of hell from whence it came
2003-02-21 Jeffrey Stedfast <fejj@ximian.com> * camel-iconv.c (camel_iconv_charset_name): New function...back from the depths of hell from whence it came originally. Turns out that g_iconv_open() is lame and can't handle all the stuff we used to handle in e_iconv_charset_name(). (camel_iconv_open): Use camel_iconv_charset_name() on the to/from charsets rather than camel_charset_canonical_name(). Now maybe g_iconv_open will work for charsets such as "ks_c_5601-1987". * providers/pop3/camel-pop3-store.c (pop3_connect): Reget the capabilities after a successful authentication. * providers/pop3/camel-pop3-engine.c (get_capabilities): If we are in the TRANSACTION state and CAPA did not list UIDL as a supported command, try checking for it the hard way. svn path=/trunk/; revision=20033
