My customer has been asking me about Mailing lists. like [email protected] and it mails everyone that entered their name on signup! Would this be a hosting feature or would they need to find it out on there own??
I am kinda wondering about it too. For my hosting service so i could just mass mail all my clients ...
Have him get a php, cgi, etc script that does that. Also, sometimes web hosts provide pre-installed mailing list management scripts like Majordomo with their package.
So, even if you don't plan on offering something like this for every web hosting package, you should help him find a good script. The good thing about helping him find a good script, is because you won't be getting all kinds of scripts installed that like to take your server down and also you can at least know a little bit about the script their talking about when they have a support question.
