Why not use your ISPs smtp server then instead, maybe they have authentication you can use if they don't have open relay?

To be really sure, you'd want to check out the logs of the communications, if your client has that feature. Also note that, if you're not using SSL, you're most likely transmitting your password in plain text, so don't choose a tremendously important password for the job if you have a choice.
