MAIN12C - Email ID
Everyone loves Swampy. Swampy the Alligator lives under the city and yearns for a more human like existence. One day Swampy thought to learn the intricacies of the internet. He went to a book store in SwampVille immediately and bought a book on "Basic Internet". After reading the book Swampy decided to try on some exercises. The exercise demanded Swampy to report all valid email-id's in a given free-form text string. Check output section for exact specification. Swampy lacks the intelligence of humans and therefore needs you to help him in this job. The chapter defined email-id's as a string consisting of two parts. From left to right, these are username and site-address. The username is non-empty string of minimum length 5 build from characters {a-z A-Z 0-9 . _} (excluding the brackets). The username cannot start from '.' or '_' The site-address is build of a prefix which is non-empty string build from characters {a-z A-Z 0-9} (excluding the brackets) followed by one of the following suffixes {".com", ".org", "edu", ".co.in"}. There is no space character in the email-id. The entire email-id is "username@site-address".
Input
First line of the input contains an integer T, the number of test cases. Then T test cases follow. Each test case consists of String S on a single line. S is made up of characters {a-z A-Z 0-9 ~!@#$%^&*()<>?,.} (excluding the brackets) and space character too.
Output
For each test case, print Case #X: K, where X is the test case number starting from 1, K is the number of email-id's found in S, and then K lines with email-id's found in S.
Example
Input: 2 svm11@gmail.com svm11@gmail.com svm12@gmail.co.in Output: Case #1: 1 svm11@gmail.com Case #2: 2 svm11@gmail.com svm12@gmail.co.in
Constraints: T <= 100 |S| <= 10000

This problem seems easy, maybe too easy for classical. There are some unclear/strange things about the problem description, which may account for why nobody has gotten AC yet:
