asked on Sending mail out with comcast isp
I'm trying to set up a home network with an email server as well.
Lynksys Wireless 300N gateway router.
Winserv 2008 smtp enabled, firewall diabled
No Exchange installed yet
Comcast blocks port 25 and they use port 465 for incoming and 995 for outgoing. In the router, on the single port forwarding page, I set "External Port" to 995 and "Internal Port" to 465, and then set it to forward to my winserver 2008 with smtp enabled (no Exchange server installed). I use canuseeme.org to see if the outside world can see the opened ports. It can see port 80, which I also opened up, but I cannot see port 25, 465, or 995
Anybody have any experience setting up an email server when you have a comcast isp? I don't even need incoming mail, I have a Sharepoint site using port 80 and All I want is to be able to send email alerts to addresses outside of my network.

Yes they block 25, but they told me I could use 465 for incoming and 995 for outgoing. The problem is that even after opening these ports on my gateway router and disabling windows firewall, I have used canuseeme.org and it tells me it can see port 80, which i also opened up, but it can't see 465 or 995, so it doesn't look like anything's going to happen until those ports are showing as opened.
Are you saying that if I merely relay the mail from my smtp server to their mail server with my account credentials, I don't need to bother to have these ports opened?

Thanks for the extra clarification
What you want to do is relay all your mail to your ISP's SMTP server. You will need to enter the authentication information (your comcast email username and password) into the windows 2008 SMTP server and select the relay host (your isp smtp server)
I am doing this with another ISP but the procedure for any ISP is the same.
Does comcast block incoming port 25 ? If they do you are stuck on the inbound side unfortunately.
