Well, I see just one email notification, have you already submitted your second? I tried on the "Demo" logbook here and I got two notifications. This can of course be turned off with the option "Suppress email on edit = 1". Maybe you are using this?

Hi Stefan,

I now cannot even reply to you in the message id thread; I keep getting:

Proxy Error

The proxy server received an invalid response from an upstream server.
The proxy server could not handle the request POST /elogs/Forum/.

Reason: Error reading from remote server

Apache/2.2.3 (Scientific Linux) Server at midas.psi.ch Port 443

It is, I think, something to do with the html coding (as I normally use plain, I don't come across this as an issue).

However, in the cause of the experiment, I will submit this entry, then go back and edit it, and if I don't get
Proxy Error, then that certainly will be something to do with the html coding.

And this is an extra edited line - if you see this, I got past the proxy error issue this time.  But did you get two
emails?

That is interesting.  I can make 1 (one) submission to a thread which uses html coding, then I get hit by proxy errors. 
But I can edit, play around or whatever if it is in plain coding.  Yet to see how many emails were generated...

Hi Stefan,

I only got one email in response to the second entry of this thread, no email was received after the edit of the entry.  The
next email received was due to the third entry of this thread.

Ok, let me try (sorry to all the users who subscribe to this forum for pestering you...):

1st reply to your entry.

1st reply edited.

I got two email notifications, the second one I attached as a screen shot. So I don't know what happened in your case. The problem 
with the proxy is sometimes related to slow internet connections. If the HTML code transported over the internet has some delay 
between packets, the proxy server sometimes drops the connection. I don't know how to fix that in my Apache. If you edit in HTML, 
your browser downloads the JavaScript code and icons for the edit window, which is a lot of data, so the dropping is much more 
likely.

Hi Stefan,

I confirm that this is a slow internet line, so that explains the Proxy Error.  

Maybe I should just keep my head down on threads where people use html coding ;-)

Did you receive two emails to my entry 66677?  I only received one.

I only received one email to your posting 66680 - the first entry, not the edited version.

I checked my email server and found that the second message really went though it. But then I realized that there is indeed the "Message-
ID:" in the email header (which I completely forgot in meantime). So maybe George Paplexis is right in that some mail 
server/forwarder/receiver ignore a second email if it has the same ID. That would mean however that I have to introduce a "revision 
number" for elog entries, which gets incremented on each edit and gets attached the the message-ID, so that it becomes unique again. 
That's quite some work and has to wait a bit.
