Module development and code questions

Hi I'm new to drupal development and am need to alter the behaviour of the authentication process so that passwords aren't case-sensitive (ie the input password is strtolower()ed on insert, and there after compared to the db password . I've tried mucking around with hook_user and hook_alter_form, but haven't worked out the best way to tackle it.

If anyone has been down this path before and has any suggestions, much appreciated.

Thanks

Steven

HI guys,

The Project:

We are actively seeking a person or company with extensive Drupal experience. We need an expert programmer/developer to customize and automate many of the Drupal features. This will be continuous work for months/years into the future. We will pay a premium, but only if you're a rock star and can help us deliver what we want and need. We don't have time to foster "on the job training," so please, no newbies at this time.

Note: As a good rule of thumb, if you feel you could write a book on Drupal, then you're probably a perfect fit. (We're reading the other book right now).

You'll be working with 2-3 people over the next few months.

The Team:

Systems Administrator - You'll be working with our system administrator who operates our servers and is a Debian GNU/Linux veteran. You'll help create modules for existing account, maintenance and billing scripts. The scripts must ultimately be executed through Drupal as a module in the "best practices" way.

User Interface Designer - You'll help our XHTML/CSS experts with preparing and planning out themes for easy module integration. We have the best CSS talent you'll find anywhere, we just need to prepare our themes in a "best practices" way. Show us the basics and we'll Drupalize our current themes.

Bounce mails was to handle all the mails returned to your drupal site and block these mails after admin defined no. of attempts, so that it wont send the mail again. This module was initially developed for our purpose on our www.gleez.com way long back, we get lot of bounce mails and its hard to handle manually. So we decided to develop a module to handle the bounce and stop delivering the mails.
