Can't telnet to port 25 on the host.
Hi, we have recently setup a new UNIX server with solaris 10 and I am having issue with with SMTP/sendmail.
telnet localhost 25 --- works
telnet hostname.domain.com 25 -- does not work.
# telnet hostname.domain.com 25
Trying 10.122.1.111...
telnet: Unable to connect to remote host: Connection refused
I am a novice to sendmail but running a 'netstat -anf inet | grep 25' does not show port 25 listening on this host as it does on the other servers we have.
Your help needed... thanks!
Addition...
The ping command on the hostname works and below is the host file entry.
::1 localhost
127.0.0.1 localhost
10.122.1.111 hostname.domain.com hostname loghost
10.122.1.182 mailhost

telnetrc
telnetrc(4) Kernel Interfaces Manual telnetrc(4)
NAME
telnetrc, .telnetrc - Specifies setup commands for a telnet session
SYNOPSIS
$HOME/.telnetrc
DESCRIPTION
The .telnetrc file contains the setup information for a telnet session. It is a hidden file in your home directory and must be readable by
the user logging in.
The file can consist of multiple entries for each remote host to which a user can connect. A remote host entry consists of multiple lines.
The first line is the name of a remote host. The subsequent lines must begin with blank spaces, and contain telnet subcommands. These sub-
commands are processed as though they were typed in manually. Lines beginning with a number sign (#) are comment lines. See telnet(1) for
a complete list of telnet subcommands.
To specify subcommands that apply to all systems, create an entry, using the word "DEFAULT" as the system name, and specify the telnet sub-
commands in the subsequent lines.
EXAMPLES
The following shows a sample .telnetrc file:
# Beginning of telnetrc file # Default subcommands that apply to all systems DEFAULT
environ undefine USER # First system entry system1
set echo
toggle crlf # Second system entry system2
set echo
mode line
toggle crlf
FILES
User-customized telnet startup values.
