Hey, I've created a mailbox user, e.g. firstname.lastname@example.org. People will send mails with an attachment at this mail address. Now, I would like to create a script which automatically extracts the attachment on my server and which does some other operations. Is there a possibility to accomplish this with postifx? Or should I use a server cronjob which checks the mailbox every 5 minutes for new mails? Thanks for your help!
