Sendmail. Can I stop incoming mail

[Tim O'Connell]

I have just got sendmail working to send to external(Internet) addresses but I want to prevent any maild being sent to my HPUX11 server. Is it possible to allow outgoing mail but prevent incoming - to stop listening on port25.

Thanks,

Tim

Just shut sendmail down - /sbin/init.d/sendmail stop

Change SENDMAIL_SERVER=0 in /etc/rc.config.d/mailservs

Outgoing mail will still work....

Just add /usr/sbin/sendmail -q
to cron say every hour to process anything that may not have been sent...

Hi Tim,
If you don't want to allow incoming mail, you can disable Sendmail, while still using mailx to send messages.

If you need to use a specific mail relay for outbound, however, this may not work. I will have to try it and see.

Hope this helps.

Thanks for the prompt reply. Setting sendmail_server to 0 works

Thanks,
