Ha sanyone any idea why emails from one paricular source can take up to 3 days to eventually arrive. When they do arrive they are alsways marked as being sent in th eearly hours of the morning.

The same email copied in to my son at a different address always arrive promptly, as do all my other emails.

I use bt openworld broadband. (or whatever they call it today!)

Traffic. If there are huge backlogs waiting to process through on the way, it'll take longer.

No, I don't think its traffic. It only ever happens with this one sender, and his cc'd emails arrive immediately to my sons account on my pc, whereas to me they are taking as much as 3 days.

Flippin heck, he might as well use snail mail if it wasn;t for the exorbitant cost there.

your and your sons accounts both with the same ISP ?

if not, might simply be your ISP is taking your mail servers down early in the morning for maintainence.

IF a mail is delayed, typically the sender will recieve an error report, detailing the fact its been delayed, and why.

Might also be your mailbox is full.. but typically thats a terminal error.

No I dont think its any of those things. Its really strange.

I have a bout 3 accounts - BTinternet, tesco.net and beeb.net.

All my emails from whatever source and to whichever account I have always arrive pretty much instantly.

However emails from this pal of mine generally arrive up to 3 days later, and generally indicate that he sent them at some daft time of the early morning.

The identical message, cc'd to my son (or cc'd to me after being sent to my son) arrive in the normal way to his Claranet pop mail account.

The account which arrive late is to my btinternet account which otherwise performs faultlessly.

Conversley, emails which I send to my pal arrive to him in the normal time frame as you would expect.

He never gets any error messages about his sent emails.

It doesn't appear to happen to any of his other sent emails, just mine. Typical!
Very strange.

Not all mail servers will notify of delays. It looks like clara.net use qmail, for example, which does not.

Have you looked in the email headers to see if it says anything in there?

Er.... I have looked a bit more carefully, and its the recieved time that is late, but the sent time is correct. Why the 36 hour dely between sending and recieving?

Assuming you are using outlook or outlook express to view your email..

For Outlook try right clicking on the email, and choosing Options. Here you will see "Internet Headers"

In Express, right click the message, Properties - Details

Paste the entire contents of this bit onto here and I (or no doubt someone else) may be able to tell you where the delay is.

Simply put each mail server that the mail passes through should add a received header which contains a number of pieces of information. One of these will likely be the date and time stamp. By working from the bottom up and looking at the date and time stamp in each received header, you can identify at which point the delay came.

Whether this gets you any closer to solving the problem is another thing, but pinning down the location of the delay is the first step in finding the cause.

Here's an example of a message from our web server - you can see that there are timestamps in each Received header:

Received: from [217.8.240.103] by mail.skinfull.co.uk (GMS
10.02.3267/AB0000.00.cbe4b227) with ESMTP id zqwaqiaa for
xxx@skinfull.co.uk; Mon, 27 Sep 2004 14:22:06 +0100

Received: from [217.8.240.20] (helo=kilo.rb.xcalibre.co.uk)
by foxy.xcalibre.co.uk with esmtp (Exim 3.36 #1)
id 1CBvKK-0004a6-00; Mon, 27 Sep 2004 14:14:00 +0100


What this tells me is that assuming the time on both servers is exactly the same, then it took 6 minutes and 6 seconds to send this email.

As you can see, it was sent at 12.24 on 30th Sept.

I recieved it on sunday 3rd oct @ 02.12

does that mean BT have been hanging on to it?

I would say yes. Again, assuming that the timestamps are correct, here's the relevant bit.


Received: from 193.113.154.33 (HELO c2bapps17.btconnect.com) (193.113.154.33)
by mta802.mail.ukl.yahoo.com with SMTP; Sun, 03 Oct 2004 02:12:18 +0000

So you can see that it arrived on the BT server and then sat there for days. If I had to guess I would say that the sheer volume of mail that is queued for Yahoo is causing the delay.

We see this a lot for some customers - massive queues which can't be processed quickly enough because the big providers like yahoo and hotmail are so strict that they will drop connections at the first opportunity, forcing a re-queue. No surprise to see BT suffering from this. Might still be worth taking the above header and emailing BT support though.

The sender is using bt connect to dial up isn't he - sending via their mailserver.

It's certainly the bt connect mailserver holding onto the mail for too long.. although why it only happens in your case has me stumped. If all bt connect customers were getting this delay when sending emails to all bt internet customers you'd think someone would have noticed by now (even if it is run by Yahoo)

Get him to dial up with someone else

Could just be that the "dswu194" server is screwed...
