В наше время, когда каналы интернета были не такими широкими, мы иногда использовали сервисы типа
FTPmail и ряд других, где можно было команды/запросы подавать по email.
Обратите внимание на
ftpmail скрипт:
https://linux.die.net/man/1/ftpmail
ftpmail(1) - Linux man page
Name
ftpmail - FIFO-based Perl script for sending email based on proftpd TransferLog
Synopsis
ftpmail [ --help ] [ --fifo fifo-path ] [ --from email-address ] [ --log xferlog-file ] [ --recipient email-address ] [ --subject email-subject ] [ --smtp-server server-address ] [ --attach-file ] [ --auth smtp-auth-info-file ] [ --ignore-users regex-pattern ] [ --watch-users regex-pattern ]
Description
ftpmail is a Perl script designed to read ProFTPD's TransferLog log entries, watching for uploads, and to send an automatic email notification when uploads occur. To use ftpmail , you configure your proftpd daemon to write its TransferLog to a FIFO; the ftpmail program is a FIFO reading program which then processes those log messages.

Думаю вы сами скачаете скрипт, разберетесь, перепишете, и будете не общаться с FTP сервером посредством email, а делать то что нужно по условию вашей задачи.
