When I setup my system to have POP3 access to email, it seems to run for a short period of time (many times once) and then I no longer get email from the server. Running sendmail, procmail, spamassassin ipop3d (included with fedora imap package) and installed clamav. What I've discovered is that the /var/spool/mail/user file gets overwritten with the following text: >From MAILER-DAEMON Thu Apr 22 11:50:17 2004 Date: 22 Apr 2004 11:50:17 -0700 From: Mail System Internal Data <MAILER-DAEMON@xxxxxxxxxxxxxxxxxxxxx> Subject: DON'T DELETE THIS MESSAGE -- FOLDER INTERNAL DATA Message-ID: <1082659817@xxxxxxxxxxxxxxxxxxxxx> X-IMAP: 1082659816 0000000002 Status: RO This text is part of the internal format of your mail folder, and is not a real message. It is created automatically by the mail system software. If deleted, important folder data will be lost, and it will be re-created with the data reset to initial values. I found in the /var/log/maillog the following lines: Mailbox Vulnerable - Directory /var/spool/mail must have 1777 protection Does anyone know what's going on?
