???

Ok people lets see if we can figure this one out. I have a pop3/smtp running off windows 2k3 server standard edition (iis smtp and builtin pop3 using ads integrated authentication)

I have a dns record from my web host for my mx pointing to my static ip and fqdn for my Lan gateway.

I have opened 25 and 110 and frowarded them to the dedicated nic for pop3/smtp for that server 192.168.0.3

I have internal DNS with an mx record pointing to the same mx server as my webhost (my lan gateway) I have tried with and without an internal DNS record for the mx.

I can send mail from my house using my mailserver from work

I can receive mail from anyone at work from home

I can send email to anyone at work from home using the work mailserver

I cannot however get it to accept email from my home isp mailserver the mail hasn't bounced back yet but it doesn't deliver and it's not in the bad mail folder
(default c:\inetpub\mailroot\badmail)

WIERD! Any suggestions? I had this issue before and somehow i found something on the ms site which told me to add a special type of dns record into some place in my dns server jsut can't remember where and i cant find the article

Thanks all in advance

Use a subject when you're posting, there's more chance you'll get a reply. I only read this post because I was using the 'Next Thread' link - otherwise I wouldn't have bothered.

I find telneting on to the SMTP service always a good idea for diagnosing these kind of issues. You will need to find a computer out on the internet somewhere, maybe at a friends house...
Open a command prompt and type:
---
telnet mail.yourdomain.com 25
ehlo
mail from:test@testdomain.com
rcpt to:yourname@yourdomain.com
data
hello

The last . on a line of its own is important. Replace all the domain names and e-mail addresses as appropriate. Any errors that come up should give you a better idea of what is going on.
