For most people, allowing PLAIN and LOGIN SMTP AUTH is no greater risk than they already have, since POP and IMAP *also* transmit unencrypted passwords. Hence, no damage done by removing the 'p'. I think it should work with that one change. Try it and see! Cheers, -- Rodolfo J. Paiz <rpaiz@xxxxxxxxxxxxxx>
