I am unable to receive new mails (the connection between the client and the server runs fine, but the server is not getting new mails) I'm also unable to send new mails.

I was setting up bandwith monitoring in Webmin the other day and had to install iptables and such. Since I set iptables to allow any traffic, and I had no problems with the apache webserver whatsoever, I thought everything was fine.

Ofcourse I just now noticed I haven't received any new mail today. And I'm unable to send any. I already removed iptables and its settings, but no luck.

I am seeing lots of this in the mail log:

Can anyone shed some light on this?

Somehow, the /var/lib/postfix/smtpd_scache.db file got corrupted (0 byte large)

Removing it fixed everything.
