Took out code that had been there to reconnect to the server if it was not
2000-05-25 Jeffrey Stedfast <fejj@helixcode.com> * providers/smtp/camel-smtp-transport.c (_send_to): Took out code that had been there to reconnect to the server if it was not already connected - Mailer code was fixed so that this should not be needed. * providers/imap/camel-imap-store.[c,h]: Initial code. svn path=/trunk/; revision=3202
