knowledgebase/linux/mail/sendmail notes Getting flooded by incoming spam? Try these settings: 1 Setting the maximum number of Sendmail processes {code:none} define(`confMAX_DAEMON_CHILDREN',7) {code} 1 Limit connection time of incoming connections {code:none} define(`confTO_ICONNECT',`10s') define(`confTO_DATABLOCK',`5m') {code} 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 Thanks to Don Wallace (a RimuHosting customer) for these handy tips. 2006-06-27 16:35:13.0 2006-06-27 16:31:53.0
