    Fix bug in MailResponse.write() multiline string handling.
    
    The bridgedb.email.server.MailResponse.write() method wasn't properly
    converting '\n' newlines in multiline strings to SMTP-formatted '\r\n'
    newlines.
    
     * FIXES multiline string newline replacement bug in
       bridgedb.email.server.MailResponse.write() method.
