Where to find configs and logfiles

Different parts of the system keep configs and logfiles in different places.

For full config details, see the Shack Wiki

Network traffic

We use MRTG to monitor network traffic and present graphs:

Monitoring mail throughput

The mail system collects a lot of data about how hard it is working... We graph some of it with MRTG. Note that some graphs are scaled per minute and some per hour, as MRTG rounds everything to the nearest integer for display.

The number of messages passing through the system
The number of mail recipients
Connections rejected due to XBL (mostly botnets)
Connections rejected due to unwanted HELO (mostly Cutwail bots)
SMTP authentication failures
The number of messages we reject due to RBL and invalid sender addresses
Greylisting
Unknown local recipients
Valid messages delayed by greylisting
The number of messages containing malware that were blocked by ClamAV
The number of good messages against the number of spammy ones that get through the RBL and greylisting stages
The number of IMAP logins
The number of POP logins
The number of SMTP connections rejected due to system limits
The number of Exim processes running
The number of running POP and IMAP daemons
