Don't forget to unref the SASL object.
2001-03-02 Jeffrey Stedfast <fejj@ximian.com> * providers/imap/camel-imap-store.c (try_auth): Don't forget to unref the SASL object. * providers/smtp/camel-smtp-transport.c (query_auth_types): Implemented. (smtp_auth): Implemented. (smtp_helo): Don't bother parsing the authtypes if we already have them. (smtp_connect): call smtp_auth() here if we found any authtypes. (smtp_disconnect): Updated as I now use a hash table for the supported authtypes rather than a linked list. (esmtp_get_authtypes): modify to use a hash table instead of a linked list and also use isspace() rather than == ' '. svn path=/trunk/; revision=8525
