[otrs] Keep a copy of mail on the server

Hi, I am creating a ticket for each mail received on my POP3 account. These mails are getting deleted from my server. How can I keep a mail on the server for each of my POP3 account configured in OTRS. Best regards, Sudhakar __________________________________________________ Do You Yahoo!? Tired of spam? Yahoo!
