Please help, before I bomb MS

I have been struggling setting up the IIS smtp server for over a week now. I just reinstalled it (thinking that would reset it to default values, which doesn't seem to exactly have happened). I am able to email to my edu address, but not my gmail or cell phone addresses. I do not understand what the difference is. The messages to gmail or nextel just sit in queue.
Settings:
IP set to 'all unassigned'
Limit # of conn = 10
Conn timeout = 10 min
Authentication = Anonymous
Connection control = all except list below (list is empty)
Relay = all except list below (list is empty)
Outbound security = Anonymous

Deliver->Advanced
Here I only have my Fully-qualified domain name set to studiopc, which is what I call this computer. Perhaps this is the problem, but I don't know what else to put.
Smarthost is empty.


Any help is greatly appreciated!

Well, perhaps your email account with the universiry allows for annon users to send email, while the other accounts need an athenticated user for you to be able to send the email.



I can't say I didn't have problems as well.

My solution was to install hmailserver.

http://www.hmailserver.com - it's free and works for me

Probably a relaying issue in smtp. If you're using IIS SMTP review all the relay properties.

So if I want to send an email to someone else, I have to authenticate myself not only to my own smtp server (unless it's set to anonymous), but also to their server? How do I authenticate myself to a server (or domain) that I'm not afilliated w/?

I only see one place to edit relay, and that is in relay restrictions. I have mine set to allow relaying for my computer's IP address (which happens to be the same IP of the smtp server). Are there more relaying options that I'm missing?

I don't know, check with your email server administrator. If you try to use the built-in IIS smtp you need to make sure your computer will not be blocked by antispam filters, which is what appears to be the problem.

Maybe drop in the email forum, this is primarily an email issue not an iis issue.

You know what, I tried connecting to this hmail server using telnet last night and couldn't, but I could connect to my school's through telnet. I think maybe my ISP blocks 25, but for some reason (probably location), I am able to access the school via 25. Know any ways to get around that?

If an isp blocks port 25 then you need a mail host like mine that offers a different smtp port. Perhaps there is some connection between the isp and the school? Typically large ISP's like AOL block port 25 access to servers that are not on their network, but allow port 25 to go to smtp servers that are part of their own network.

But if port 25 is blocked I know of no way around it other than getting it unblocked or using an alternate port.
