The work algorithm:
1 . As a input data, there is a text file in which the email address is recorded (one in each line)
2nd The script must strictly take the lines (with removal) and perform the following actions with the taken box:
2.1 You need to know the mx domain record (example of the command: "nslookup -q=mx mail.ru") - the address of the mail server will be returned as a reply (e.g. "mxs.mail.ru")
2.2 Then using telnet we connect to the mail server (we enter three commands and get the server's response about the existence of the mailbox)
2.3 If the server’s response is positive, we transfer this box to the output text file. If negative - we remove this box and take the following from the input file.
Requirements :

Start on a console (in the Linux terminal)
