Hi, I keep recieving receipts from cron-daemon for local email deliveries. Basically I setup a crontab to run fetchmail but ever since I started forwarding it with a .forward file I've been receiving receipts from cron to my inbox which are blank emails. I've also been told that my server is sending blank emails to anyone it receives an email from. How can I stop this? I have no idea what is happening and why either! Also I would like to integrate spamassassin and clam_av into the mail chain to scan incoming mail and any advice or links to this would be great too as I've had no luck so far apart from nearly breaking my mailing system! Thanks in advance.
