They want me to give them my email info and password???

One day I received the email message below in my INBOX from a sender that I didn't recognize:

Dear Webmail User,

This message was sent automatically by a program on Webmail which periodically checks the size of inboxes, where new messages are received.The program is run weekly to ensure no one's inbox grows too large. Ifyour inbox becomes too large, you will be unable to receive new email.Just before this message was sent, you had 18 Megabytes (MB) or more of messages stored in your inbox on your Webmail. To help us re-set your SPACE on our database prior to maintain your INBOX, you must reply to this e-mail and enter your

Current User name ( )

and Password ( )

Webmail Login address ( ) eg webmail.domain.com

You will continue to receive this warning message periodically if your inbox size continues to be between 18 and 20 MB. If your inbox size grows to 20 MB, then a program on Bates Webmail will move your oldest email to afolder in your home directory to ensure that you will continue to be able to receive incoming email. You will be notified by email that this has taken place. If your inbox grows to 25 MB, you will be unable to receive new email as it will be returned to the sender.

After you read a message, it is best to REPLY and SAVE it to another folder.

Thank you for your cooperation.

Needless to say, I didn't comply with the request. WOULD YOU?
