how do I configure sendmail to be able to send mail outside my network

dkscomps · 07-01-2004, 11:02 AM

I am running Slackware 9.0 and have a webserver and email server runnuing. 1st I can not send mail from another network outside the home. 2nd I cant access my webpage from inside the nework using its given name, I have to use the local ip address of the box. Help.... I am new to linux and have tried a few things to just make things worse. Now I cant send mail from inside the network either......

Ok to start off your isp will block port 25 which is used to send email out. Change your outgoing SMTP connection to use your isp mail server. Also you will need a static ip and registar your domain name resolve to the static ip. www.dyndns.org is a great start

Actually I do have a staic ip address and it is regisered with dyndns.org That part is fine. The real problem is My mailserver is a box at home and I want to be able to send emails from that server when I am in the office using outlook. I can receive mail off the server but it wont send. Any ideas with that???

like he said you isp might block the port 25 wich sends emails

if it does (contact your isp to find out) then you will have to use your isp's mail server to send mail

Most all ISP block port 25 to keep the spamers off their netwrk and port 80 so people dont host their own webpages.

Check ur mailserver settings for blocking relay capabilities. Mine is set to relay from local network but to block relay from outside network. A common config to fight unwanted relaying.
