Hey guys,

I've been banging my about this for so long I'm sure I'm just going round in circles.

I have an exchange 2003 Server emails appear to get stuck in the queue.

I have run smtpdiag and this is the output I get:


Searching for Exchange external DNS settings.
Computer name is ******-SERVER.
VSI 1 has the following external DNS servers:
208.67.222.222

Checking SOA for ****construction.com.

Failed to receive data. Error: 10054
Error: Expected "250". Failed to get a response from the server.
Failed to submit mail to mail.asemconstruction.com.
[/CODE]

I keep getting Error:10054 no matter what email server I try to send to.

If however I telnet into a mail server it works perfectly fine and I get no errors :(

This is doing my head in!

Any help would be greatly appreciated.

James

It's been a long while since I looked at Exchange 2003, but a good place to start would be to enable SMTP logs; http://www.msexchange.org/articles-tutorials/exchange-server-2000/monitoring-operations/Logging_the_SMTP_Service.html

Have you looked/checked all services are running?

looks like firewall or something?

I thought that, all the ports are open. Could this be as simple as a faulty router?

All the services are running yes I'll get a log in a moment.

Sorry, you can telnet from the exchange server to the server it's attempting to reach then?

As a quick fix can you not relay via your ISP's mail server (Smart Host)?

Yes I can telnet to the mail server perfectly fine and issue commands without being booted.

I'm just about to try the smart host now.

--EDIT--

Okay..... The Smart Host hasn't worked. Setting up the smart host still gives me the same issues. In the queue I have this error message:

The connection was dropped by the remote host.

when you are running telnet, are you running it from the mail server? This would test port 25 on the mail server to negate any firewalls.

Next you will have to try to find an application conflict, you should also check to see if your smtp service is running as well as your transports. I don't have a 2003 server to help you troubleshoot, I am going off memory and I believe you have to have the microsoft smtp service enabled to even think about sending and receiving mail.. also you will need to make sure the exchange routing engine is started in services.msc

Look at your event logs as well for errors.

I have indeed been running the telnet commands from the mail server.

The SMTP service is started as is the exchange routing engine, both services have also been restarted and still not working :(

You have something that is stopping communications. Do you have a spam filter? What is the outbound rate limit (this will log jam the crap out of your server).

Looking at your log, I would say that you have a low rate limit set on your outbound mail filter. Just to the 1 IP you have over 100 going to it. Set it to 200 or 500.

Here is a pic of my barracuda you will see that it is at the default, some are much lower set to around 50 per Sender.

At the moment these limits are off...

The one that is on was already set to MUCH higher than 500

Just took another look at that log file....postfix is your smtp outbound, you will need to check that box to allow through....it is caught up in there. Judging from the codes you are getting...fix your spam filter.

We don't use PostFix :s There is nothing installed on this server apart from exchange.

lets start simply....do you have a spam solution outside of your exchange solution?

do you have anything setup in your smarthost?

Servers/Your_Server/Protocols/SMTP/Your_SMTP_Virtual_Server

Right-click Your_SMTP_Virtual_Server, and then click Properties.

Click the Delivery tab, and then click Advanced.

In the Smart host box, type the name of the smart host server.

There are 2 areas that I can remember where you can add a smart host....this is one of two.

lets start simply....do you have a spam solution outside of your exchange solution?

No, Exchange is configured to send mail via DNS, we aren't using a Smart Host. The email is not configured to "go" anywhere else.

sorry looking at other domains in your mail logs. It could be on there end causing the issue and you will have to wait for their mail server to accept mail from you again, if they have a low rate control (the top field in my pic above). (you have no control over this). try sending mail to a gmail or yahoo account. does it work?

Is all mail being queued or just mail for one domain your sending to?

It looks like it is ANY domain.

I cannot send to Outlook.com, gmail.com, yahoo.co.uk I cannot send to any domain at the moment.

SK[' timestamp=1361543358' post='595536764]

Receiving OK?

I am receiving emails perfectly yeah.

Hi,

Port 25 is a wide open SMTP port - have you checked for a higher range port that supports SSL or STARTTLS?

What other ports can I use? I here 10025 is used in places? Doing this won't cause issues will it?

If you look at the log file he posted, it looks like the majority of it is spamming domains and those domains have stopped allowing him to spam them. download it and organize by column c...100's going to the same ip addresses. there is 1 ip that has less than 15. everything else seems to be very very high.

would it be possible to setup a teamviewer session so that I can see what is going on. it is completely up to you, I am willing to led a hand if you would like me to.

SK[' timestamp=1361543629' post='595536778]

I looked at the log, tried to open it in Notepad which failed hard.

Shove your external IP in here to see if your on a spam database... http://www.spamhaus.org/lookup/

yeah, try excel viewer.

Yeah I've checked for spam listings, they aren't listed anywhere.

If you want to private message me, then I can set this up thanks.

    • We need a game update frequency setting. * Right now your recent games will be auto updated overnight, and your unrecent games won't be updated. The bifurcation of recent and unrecent is fine, but we should be able to control the update frequency for both, with any of the following options: 1. Don't auto update 2. Auto update weekly 3. Auto update overnight 3. Auto update immediately (push) i.e. When I'm playing a lot, I want my recently played games to have push updates, so if a dev releases an update at 4pm, it's already downloaded on my Xbox by the time I get home. The current overnight cadence leaves a lot of wasted time waiting for updates on slow connections. My infrequently played games in ok with deferring to overnight, or maybe weekly, but let the users control their frequency. Basing it on data and last played sounds smart but ignores the human reality that often when I'm busiest and have the least time for games is when it sucks the most to come home and find a huge update list waiting for you.
    • Genocide is intent to exterminate and both the Israeli government AND its people openly declare, even boast about their intent to exterminate Arabs. This society of sick psychopaths has even made songs about it. Zionist means believing Israel should exist as an religious ethno-state where only Jews have rights and everyone else is second class citizen. As for the blood libel thing, we already know zionists get off on killing children. We also know Israel is a safe heaven for all the pedophiles and rapists of the world. Honestly, after what we saw in the Epstein files, I wouldn't put anything past this depraved death cult. Of course all atrocities committed by tHe wOrLds mOsT mOrAl aRmY are always "unproven or taken out of context". Unfortunately for them, their soldiers are dumb enough to leave a trail of their war crimes all over social media. Then again, when you live in a society that's obsessed with death and destruction, posting videos of yourself in the act of ransacking homes and desecrating religious monuments earns you brownie points I guess. Israel is the only society in the world where people come out on the roads for the right to **** prisoners. Also claiming that the BBC said this and AP said that without so much as a link has gotten me curious. Are all zionists this dumb? I really hope you aren't getting paid for this because this is some low effort propaganda.
    • Microsoft is bringing big performance improvements to OneDrive on Mac by Taras Buria Microsoft has announced a major update for the OneDrive client on macOS. Today, the company released version 26.098, promising significantly faster sync, optimized CPU usage, a smaller memory footprint, and better energy efficiency. In a newly published blog post, Microsoft acknowledged that changes implemented in OneDrive for Mac in 2022 brought some unwanted side effects. Due to architectural changes and the need to keep the OneDrive sync engine unchanged, Microsoft created a hidden cache folder. With time, it would cause reliability and performance issues for customers. Now, Microsoft is ditching the old engine for native sync, delivering a faster, more reliable experience. As a result of this change, OneDrive for Mac now integrates more deeply into the operating system, offers about two times faster sync performance, and uses fewer system resources. While the hidden folder still exists, the app only uses it to store files that have not been uploaded yet, link file types, and macOS-related packages. In total, even when holding hundreds of files, the temporary folder does not take more than a couple of megabytes on the drive. Besides optimizations, the new sync engine enables external drive support, allowing you to keep your OneDrive folder on a removable drive (it should meet all the requirements). Microsoft is now rolling out the updated OneDrive client for Microsoft 365 Insiders. To check if your Mac has the new sync engine, go to the About tab and check the app version. If it ends with something like 26H, you are on the new engine. If not, you are on the old one. Microsoft says it will take a few weeks to complete the rollout to Insiders, but it won't say when to expect the update in the stable channel. Big performance updates for OneDrive on Mac came right after Microsoft confirmed it would soon kill document editing in Office 2019 for Mac due to expiring certificates. This change will force users to look for alternatives or switch to Microsoft 365.
