search engine and email scripts

hi, ive not been around for a lonnnng time

but anyway, im looking for 2 scripts,
email: I would like to know if there are any email programs which i can put on my website for users so that they can sign up for an email address using my domain name it needs to have a registration page and then basic features such as send receive maybe options for a signature etc but that isnt needed

search engine just something really basic like google really, just a search bar an option to add sites and if possible some type of bot that can search and add domains

i know this is a tall order for scripts already made and another thing is i would like them to be free or quite cheap as its for a friend of mine who is a bit of a tight ***

Cheers
tony

I can only help you with the search one...

There ya go ^.^

I run a free webhosting script, and one of the options is to allow a user an email address at your site. If you don't want to offer the free hosting too, you can rip apart the code and use my email script only, or offer the free webhosting as well if you want. It's free, so check it out at http://www.multihoster.com.

Also, about the search engine script, I have never used it myself but I have heard good things about Perlfect Search. I believe it is free as well.

Hope this helps

thanks for the replies, they will help
