iis smtp nntp
group:Win 2k3 POP3/SMTP Delivery problems
iis smtp nntp:
Just built a stand-alone(win 2k3 enterprise)web, mail, file server at home using my Comcast broadband internet connect. FTp,& web functions work fine with access from any machine. My POP/SMTP function is accessed thru Outlook Express on my client machine. Although I can send and receive from both Comcast and Server email accounts, when I send to aol email addresses I get the following response: "This is an automatically generated Delivery Status Notification.THIS IS A WARNING MESSAGE ONLY. YOU DO NOT NEED TO RESEND YOUR MESSAGE.Delivery to the following recipients has been delayed." In fact, one attempt to mail a .edu address returned the following: "This is an automatically generated Delivery Status Notification.Delivery to the following recipients failed." The aol delay is now 48hrs old. Also, I can't open the at&t attachment (.dat doc) which usually explains transmission errors. How can I correct these problems? All helpful suggestions will be greatly appreciated. -- Thanx,
Hi,
You say that you run this at home. This makes me belive that your ISP is blocking port 25, as many ISPs do. If your ISP do this, you will not be able to send emails to other SMTP servers. The reason why it works to send to comcast, is probably because their SMTP server is located inside the blocking. I would recommend you to contact Comcast and verify if they block port 25. If they do, and they allow you to run an email server, you can use comcast's SMTP server as smart host. But ask them before you do that, so you do not breake any agreement you have signed with your ISP. This will however only allow you to send emails. If you plan to recieve emails with your SMTP server as well, and your ISP blocks both incoming and outgoing traffic on port 25, then you will not be able to receive emails. You can also look in the Event Log for messages related to this. They might give you more information about the problem (if your ISP does not block the port). Hope this helps you. -- Regards, Kristofer Gafvert New article: http://www.gafvert.info/CSharpDataTypes.htm www.ilopia.com [quoted text, click to view] pro36 wrote:

Kristofer,
Thanx for your prompt reply. Your input is extremely helpful.As you can imagine, I'm reluctant to contact Comcast about this as this is a training server. I looked at my event viewer which revealed the following: Source: smtpsvc Category: none Type: Warning Event id: 4006 Description: Message delivery to the host '205.188.159.217' failed while delivering to the remote domain 'aol.com' for the following reason: An SMTP protocol error occurred. My MS event id search revealed the following: (4006) Replication with a nonconfigured partner is not allowed. ERROR_RPL_NOT_ALLOWED. However, I did not find a solution or workaround on the MS website. Can you help? thanx, pro36 [quoted text, click to view] "Kristofer Gafvert" wrote:

Thanx Jeff for your input.
I think I may already have a static ip address generated by my dns service. When I ping my domain name from my client machine and enter the resulting ip addr in my browser it produces my http web page. Would that not qualify as a dedicated ip addr? Also, please tell me if any of the following would help: Installing; DNS, Exchange server, an additional nic card, or using Network load balancing to complete reverse dns lookup. thanx, pro36 [quoted text, click to view] "Jeff Cochran" wrote:

Thanx Andrew for your response.
From the virtual server page of my router I opened port 23. From the cmd window I typed "telnet 23" then "25", "telnet port 23" then "25", "telnet 205.188.159.217", "telnet o". All attempts returned "could not open connection to the host on port 23" Connect failed. Do you know of a way to work around this connection problem? thanx, pro36 [quoted text, click to view] "Andrew Hodgson" wrote:

Telnet to one of the AOL mx machines and see what response you get on port 25. I am guessing you will get a multi-line 5xx response, followed by a socket disconnection. The server thinks this is a server issue and attempts to requeue the message until it gets too old and is returned to you. This is exactly what my Linux Qmail did when it was on a machine which was blocked by AOL (AOL block most residential ISP dynamic IP address pools, or machines with no reverse DNS entries).

Get a dedicated IP address that isn't part of any broadband IP range. AOL is one of the ISP's that assumes mail from dynamic IP addresses, addresses without valid reverse DNS entries and IP's from broadband home networks to be SPAM.
telnet 205.188.159.217 25
You want port 25 not port 23. Instead of an IP address you can enter a FQDN, as well: telnet aol.com 25 (or whatever the FQDN for aol's mail server is...)

Only installing DNS has anything remotely to do with reverse lookups, and that's not your problem. Your problem is that while "mail.yourdomain.com" may resolve to "1.2.3.4" looking at the IP address of "1.2.3.4" resolves to "host4.ispdomain.com", which indicates your system has a high probablity of sending spam to many ISP's. See a DNS group for details on how DNS works. Jeff [quoted text, click to view] >thanx,

Thanx Peter,
Your response was extremely helpful. My telnet to aol returned a 554 error stating "AOL does not accept e-mail transactions from dynamic or residential IP addresses". I guess my question now, shy of switching isp's, is are there any router or tcp/ip settings that can be configured to correct this? thanx, pro36 [quoted text, click to view] "Peter D. Hipson" wrote:

The only solution is to get a static IP from your ISP.

Thanx Kristofer,
Problem solved- entered isp's DNS address in default smtp Virtual Server properties in delivery at smart host. Now sending and receiving from my own mail server with no problem from aol, netscape, etc. pro36 [quoted text, click to view] "Kristofer Gafvert" wrote:
