This is because the system will fetch everything in the configured folder (in this case INBOX). POP3 is an old (seemingly outdated) protocol and doesn’t support the latest features (eg. Folders/Labels) like IMAP does.
Ideally, you’d want to use IMAP. First you’d clear out the INBOX of old/already processed/unwanted mail leaving only mail you want processed by the system. Then you’d want to create a folder (Label) within the mailbox (in Gmail) to archive (move) processed mail into; call it whatever (eg. ProcessedTickets). Then for the email settings in osTicket you’d configure IMAP info instead of POP (Hostname, Port, and Protocol), set the Fetched Emails setting to Archive - move to folder, input the folder (Label) name (eg. ProcessedTickets) in the input box that appears, and Save Changes to test connection and see if it can find the folder (Label). Now, with this configuration when mail is fetched from the INBOX it gets processed, creates a Ticket (or gets rejected), the mail gets moved from the INBOX to the Archive folder, and repeats. This keeps the INBOX clean and prevents old mail from being processed.
Cheers.
