The script was designed to be used on a mail gateway where outgoing mail either is sent via the localhost or a smart host, and incoming mail is forwarded to Exchange or something similar, so the localsmtp server is assumed to be different from the system running the script. > If I allow all mails from localhost by using filter_sender with $ip check, > I am not able to quarantine mails sent from the server.

Removing user access to your mail server would be the easiest approach, but may not be practical or politically acceptable. One possible approach would be to have the quarantine script add a header when re-sending the message, or to have it prefix the subject, and then have your filter check whether this is in place. For send_partial, adding a header is relatively simple, by using MIME::Lite's "add" method, but send_entire subroutine uses Net::SMTP because all of the necessary information is already in the message array, so you'd have to manually process the @msg array to insert a header or change the subject line. In either case, you'll have to partially re-write the script to achieve what you want, and then work out a way to generate a flag which can't be discovered and spoofed by your users, such as having a database of MsgID/flag pairs which is added to when a message is quarantined, and from which quarantine.pl can pull the flag to add before releasing the message. If the database is only available to the defang user, it would be relatively secure.
