Courier Connection Refused

Jump to: navigation, search

The office was getting lots of connection timeouts and connection refused to the Courier IMAP server. The solution was to increase the max number of daemons allowed and the max per IP allowed. Edit /usr/local/etc/imapd:

##NAME: MAXDAEMONS:0
#
#  Maximum number of IMAP servers started
#

MAXDAEMONS=200

##NAME: MAXPERIP=50
#
#  Maximum number of connections to accept from the same IP address

MAXPERIP=200
