You're in the
iis smtp nntp
group:IIS6 SMTP Server
iis smtp nntp:
After a server reboot mail is forwared, but all new mail still sits in the queue. The logs say the remote domain can't be found and sent mail is delayed. Other times mail goes into the Badmail folder and I know those emails have valid from and to addresses. All mail is being sent trough our website on same server using cdonts. After server is rebooted all seems ok for few hours or/and all old mail is being sent from the queue and new email gets stuck in the queue again?

A lot of stupid servers today use something called greylisting which assumes that a spammer won't try and send an email twice so they reject all emails once and expect legitimate servers to resend it. That could be one reason your queue is getting full, check into your resend intervals and when delay messages should be sent out (usually not on first retry). If it says the remote domain couldnt be found it's either invalid or you have a DNS issue on your machine, pherhaps the DNS server is unavailable at times, do you have a backup listed (ipconfig /all) ?

There are two dns servers that we monitor and always are up I even tried manually doing lookups just to make sure it's not DNS. All was fine, this just started happening. First all email was forwarding to the badmail folder, after a couple of reboots it started to get stuck in both badmail and queue(it's not delayed it gets permanently stuck until I look and delete it manually). Just rebooted the server again, and all email is going trough ok for now, pretty sure it's going to get stuck in the queue shortly. Only a small amount of emails are actually relayed trough IIS
Well, I don't know, seems a lot of people are having issues right now, maybe somekind of attack. Check your eventlog to see if you can find any errors or warnings that might be related and change your smtp service logging so it logs as much as possible.
hi
i want to install and configure smtp service on iis 6, i try to do that but nothing work good> if any one can help me, please send me an email. Thanks . . . . From http://www.developmentnow.com/g/92_2006_6_0_0_774797/IIS6-SMTP-Server.htm Posted via DevelopmentNow.com Groups
Hi Jakeyy,
I have the exact same thing going on here! At about 12:30PM EST, messages just hang in the queue folder and are not delivered to the next hop. Rebooting the server frees up the messages for delivery for a short time, but will eventually freeze again. I've tried to send messages using telnet from this IIS server to my next hop and even THESE freeze! When I break the telnet session, the message gets delivered (should not happen like this!) If I look at my next hop (Exchange 2003), I see SMTP cennections established, but no transfer of messages occur. I've turned up logging on both IIS and Exchange servers and nothing appears in the event viewer. Occaisonally I get a semaphore timeout or connection dropped by remote server (wouold expect that after reaching timeout interval). Just like you, this JUST started happening about 3 days ago. I have a call into Microsoft. If anything comes out of that call, I'll let you know! [quoted text, click to view] "jakeyy" wrote:

Hi Jakeyy,
Sorry for the delay in posting this... What we found out is that Symantec Anti-Virus (version 9) was scanning the message transport. What had happened was Symantec was configured incorrectly and had a setting called "Internet Message Scanning" enabled. This setting is for a desktop client and should not be used on a server. After reconfiguring the Symantec AV client, my problem went away. Hope this helps you! [quoted text, click to view] "Dave C" wrote:
