For automated submission you could use SocialAdr.com which will submit your site to 16 Social Bookmark sites including Delicious, Multiply, Jumptags, etc. in exchange for you to bookmark other user's website. If you want more Social Bookmark sites you could use socialmonkee.com/index.php?af=1700 (aff link) which will automatically submit your sites to 25 Social Bookmark sites for FREE
Using automated software of tools for social bookmarking in SEO is not good but since you asked, you can use socialmarker. Doing it manually is the best because you will get good results.
