HP-UX Mailing Solutions White Paper

Prerequisites
Following are the prerequisites for configuring POP3 on an HP-UX system:
• The Sendmail 8.13.3 Software
NOTE: Sendmail 8.13.3 is available in the core HP-UX 11i v3 operating system.
If Sendmail 8.13.3 is installed on an HP-UX system, the swlist HPUX-MailServer
command displays the following:
HPUX-MailServer C.8.13.3.1 HPUX Mail Server
• The POP3 Software
You must install the latest UW-IMAP software (A.11.00-2007a.002 and above) from http://
www.software.hp.com for the HP-UX 11i v3 operating system.
If UW-IMAP is installed on an HP-UX system, the swlist UW-IMAP command displays
the following:
UW-IMAP A.11.00-2007a.002 IMAP Server
Setting up the POP Server on an HP-UX System
Follow this procedure to set up the POP server on an HP-UX system:
1. Append the following entry to the /etc/services file:
pop3 110/tcp #POP
2. Append the following entry to the /etc/inetd.conf file to start the POP3 server:
pop3 stream tcp nowait root /usr/sbin/ipop3d ipop3d
3. Reread the /usr/sbin/inetd configuration:
#/usr/sbin/inetd –c
Verifying the POP3 Setup
Follow this procedure to verify the POP3 setup:
1. Enter the following swlist, which, and ls commands to verify the installation of the POP3
software.
#swlist | grep IMAP
ixUW-IMAP A.11.00-2007a.002 IMAP Server
# which ipop3d
/usr/sbin/ipop3d
# ls -l /usr/sbin/ipop3d
lrwxr-xr-x 1 root sys 3 Aug 27 18:28 /usr/sbin/ipop3d ->
/opt/iexpress/uw-imap/sbin/ipop3d
These output for the swlist, which, and ls commands denote that the POP3 software is
installed on the system. You must obtain an output similar to this output to ascertain that
the POP3 software is properly installed on your system.
2. Establish a telnet connection from your system to the POP server on the local host:
# telnet 0 110
The following output displays to denote that the POP server is reachable:
Trying...
