If its already installed, then you should be able to start up the service. First verify that sendmail isn't already running:<BR /><BR />ps -ef |grep sendmail<BR /><BR />then do a chkconfig to verify that sendmail is set to start up in the runlevels you're interested in.<BR /><BR />chkconfig --list |grep sendmail<BR />should say something like:<BR /><BR />sendmail 0:off 1:off 2:off 3:on 4:on 5:on 6:off<BR /><BR />which means that sendmail will start on runlevels 3, 4, and 5.<BR /><BR />If its not configured to start, then do a 'chkconfig --level 345 sendmail' to configure it to start under those runlevels.<BR /><BR />Finally run '/etc/rc.d/init.d/sendmail start' to start up sendmail.<BR /><BR />Do the same thing for popper (one of the many pop servers).<BR /><BR />Hope this helps.<BR /><BR />-Santosh Thu, 06 Dec 2001 11:09:57 GMT Santosh Nair_1 2001-12-06T11:09:57Z https://community.hpe.com/t5/operating-system-linux/install-smtp-popmail/m-p/2626507#M89708 how do i start installing a s/w for smtp or pop mail on my RHLinux 7.1?<BR />do inned to download any software application or do i just have to start a service? <BR />Thanks.....
