One of you might be accessing gmail behind a firewall.

Please elaborate why this would cause a delay.

All I can think of is greylisting implemented on an MTA along the way.
See http://greylisting.org/

Some servers scan their outgoing and incoming traffic. Because of the load, some mails take hours to reach their recipient.

Hi Tony

I'm still not seeing what this has to do with firewalling.

I am a sys-admin and if an MTA was taking hours to deliver email then
I would consider that there is a problem that needs taking care of.
That kind of delay would be unacceptable and defeats the purpose of
email entirely. One may as well send a fax.

There is a troubleshooting section in gmail help for users who expreience slow delivery (but I don't know if gmail considers an hour to be a problem); there is also troubleshooting help for network or server administrators.
(Hey Marko, I wish everyone was as particular as you on system admin..!)

There are quite a lot of complaints of this problem (slow delivery) on the forums, (including gmail's help forums). some instances can be put down to the way users access their email - POP or Forwarding & how often gmail checks other accounts. But some users seem to have a delivery delay (only with gmail) that can not be explained by this.
Many complaints about slow gmail report 'instant' delivery for other webmail or accounts.

Over the 20 some odd years that I've been using e-mail over the
Internet, there are frequently very noticeable delays, for all sorts
of reasons. I don't think e-mail was intended to be instantaneous; if
it was, it has surely failed ever since day one. It just happens that
it often is.

I'm not saying there isn't a problem with Gmail. Maybe there is. I'm
just saying that e-mail isn't a system that is guaranteed
instantaneous.

For what it's worth, I have not seen this problem myself; but it
appears that it doesn't affect everyone.

I'm not saying it's guaranteed instantaneous either. It can't be, as
it is stored and forwarded from one place to another. I am saying
though that a consistent delay of an hour or more would be
unacceptable to me, and indicative of a problem.

'mpluky', there is a simple way to find out exactly where the delay is
occuring. If one clicks on the little down arrow next to the reply
button and selects 'Show original', the complete message source along
with headers will be displayed. What we are interested in are the
'Received: ' headers, starting at the lowest one, ie. in reverse
order.
Looking at the headers from your original message, there is a hint of
a possible problem...

Received: by 10.151.85.19 with SMTP id n19mr201509ybl.23.1287139262864;
Fri, 15 Oct 2010 03:41:02 -0700 (PDT)
MIME-Version: 1.0
Received: by 10.90.90.7 with SMTP id n7mr329224agb.35.1287129207984; Fri, 15
Oct 2010 00:53:27 -0700 (PDT)
Received: by 30g2000yqm.googlegroups.com with HTTP; Fri, 15 Oct 2010 00:53:27
-0700 (PDT)

You will see that the difference between time stamps of second and
third header is nearly 3 hours. So it would seem that the problem is
between a computer on IP address 10.90.90.7 and the one on
10.151.85.19 which I'm guessing both are on Google's network.

See if you can get the recipient to send you the headers of the
messages you send and compare the time stamps of those.

Cheers

Hi Vicky

Please create a new email about your problem, don't hijack this one.
In that new email, do also include as much information as possible,
eg. what browser, version, operating system etc. etc.
