sendmail notes

Setting the maximum number of Sendmail processes

define(`confMAX_DAEMON_CHILDREN',7)

Limit connection time of incoming connections

define(`confTO_ICONNECT',`10s') 	
define(`confTO_DATABLOCK',`5m')

This will stop spam/misconfigured hosts for keeping connections open for a long time.

Add these to /etc/mail/sendmail.mc, and restart Sendmail: /etc/init.d/sendmail restart
