SendMail Config

AMDPwred · 03-20-2002, 08:22 PM

Can anyone help me configure SendMail so I can connect and send email from a separate workstation on my LAN? I hear that by default it is setup to only allow local connections. Thanks for any help.

go for man sendmail and what that will give you simply is

instead of starting Sendmail with 'sendmail' start it with 'sendmail -bD'. That starts sendmail daemon. Put this option in your start up file (rc.d files). Make proper Network actions and DNS entris for your Sendmail Server.

If you are using sendmail under an RHEL derivative, the sendmail.mc file needs to be edited. CAUTION: be sure to deny relay for any network that you NOT on.

Code:

dnl # The following causes sendmail to only listen on the IPv4 loopback address
127.0.0.1 and not on any other network devices. Remove the loopback
dnl # address restriction to accept email from the internet or intranet.
dnl #
dnl DAEMON_OPTIONS(`Port=smtp,Addr=127.0.0.1, Name=MTA')dnl
dnl DAEMON_OPTIONS(`Port=smtp,Name=MTA')dnl[/FONT][/INDENT]

Insert 'dnl' in front of 127.0.0.1

In the access file, place your local network where 192.168.1.0 is

Code:

# by default we allow relaying from localhost...
Connect:localhost.localdomain           RELAY
Connect:localhost                       RELAY
Connect:127.0.0.1                       RELAY
Connect:192.168.1.0                     RELAY

run

Code:

make -C /etc/mail

You will need to restart sendmail to compile the access.db

Good luck.
