starting services everytime the redhat boots

[redhat newquality de]

Hi everyone,

i have the following problem. when my mailserver boots up, it initializes
the ports 110 and 25 but not the imap once.

currently i start them with :

/etc/rc.d/init.d/imap start

/etc/rc.d/init.d/imaps start

can i add this to lines to a file, so that this services are started
automatically everytime?

cheers

Christian
