Script - mailer

This is the script which I wrote by someone's request, and it seems getting popular.
Please feel free to make a copy of it if you find it useful for you.
The script sends e-mail to group of people individually so that each person received the mail would think that it has been sent personally just for herself/himself. Also the mail won't have the long list of email addresses at the header.
You need two files to use it; one with list of addresses and one with message.
First, the address file is like this:

	bkim@cs.uml.edu	   "Dear Bo:"      bo kim 

	anybody@somewhere  "Ms. Anybody"   friend 

	...

That is, each line consists of address, personal greeting, and any comment which won't appear in the mail message. Make sure to use '"' for personal greeting.
Second, the message file is the content of mail you want to send to group of people and can have any format you like.
If you name the address file and message file as addressbook and mymail, respectively, then the following will be the command to send mail:

       mailer mymail addresssbook

Enjoy.
