If the POP3 server receives a pickup request, the POP3 server forwards all waiting messages to the email client program on the user�s PC. To check whether you have the IMAP POP3 server installed, use this version of the rpm command: # rpm -q imap If the system responds with something like imap-4.5-3, then the package is already loaded. If not, mount your distribution CD-ROM and install IMAP: # mount /mnt/cdrom # cd /mnt/cdrom/RedHat/RPMS # rpm -ivh imap-somereleasenumber.i386.rpm You may also need to activate those services in /etc/inetd.conf. Here�s the line pertaining to POP3 before I change it in /etc/inetd.conf: #pop-3 stream tcp nowait root /usr/sbin/tcpd ipop3d Uncomment the line by removing the hash mark at the beginning. Next, refresh the inetd process for this change to take effect. Find inetd�s process id and send a SIGHUP to it. That means you do a kill -1 on the process. Be careful because a kill -1 looks an awful lot like a kill 1. The master process on the system is init, and it runs at process id 1. Kill init, and you kill the whole system. If you are concerned, use kill -SIGHUP instead of kill -1. Here�s how it looks: # ps ax | grep inetd 391 ? S 0:00 inetd 6568 pts/0 S 0:00 grep inetd # kill -1 391 # On my RedHat system, I can also restart inetd like this: /etc/rc.d/init.d/inet restart The next step is to refresh Sendmail. Back to the Index
