Re: E-mail comes in twice.: Got it, I think...

2014-06-03 Thread G Tod
Thanks for all the suggestions, everybody.  In case anyone is 
interested, here's what seems to be working so far and has been working 
for about 5 days now.  I went into my mail account through webmail and 
found a setting regarding preloading, where previously neither of the 2 
choices had been checked.  I checked:  Don't pre-load messages.  So, 
obviously the ISP had something to do with it, but I assume SM must have 
played a role also.

this happen for me in accounts of one isp, but not for the others
so may be this can be caused by the ISP

I don't know if an extension can cause the problem, but there is one 
that can solve it

I was getting this with very large messages, actually messages with
large attachments.  I set a preference under [Account Settings  Disk
Space] for my E-mail account to hold messages greater than 75 KB on the
server.  If I did not download the entire message after some elapsed
time, my ISP's mail server would send another copy of the first 75 KB.

The solution is to open the truncated message and download the entire
message.  Alternatively, you might be able to view the E-mail server
over the Web and delete the offending message.

On occasion, I filter and ignore all newsgroup messages

because of spam, flames, and trolling from that source.

Thanks for the info, but...  I have never checked To save disc space, 
do not download: messages larger than XX kb.  Also, it's not just large 
messages here, when it does happen, it's ALL current messages, no matter 
the size.  As for logging into it over the web and deleting 
therewell, that's just too time consuming for this amount of 
messages.  Any other ideas out there?

That's actually part of the POP protocol.  When you download messages, 
the signal to delete messages from the server isn't sent until the 
entire batch of messages in the inbox on the server.  Thus, if the 
download gets interrupted, then the effect can be that messages that are 
a partial batch aren't deleted, and will get downloaded again, on a 
subsequent attempt.


This kind of effect isn't common for broadband connections, but in the 
era of dialup connections, it did happen occasionally, especially on 
slow/unreliable connections. The most common occurrence I would see 
would be a batch of several hundred KB to download that included one 
message with a relatively large attachment (typically with photos).  If 
the download would abort (usually timeout), it tended to be while it was 
downloading the large message.  And a subsequent download attempt would 
re-download the beginning of the batch (already seen), and hang again on 
the large message.  I learned to call this situation a hairball. (Gag! 
Ack! Barf! Thwpth!)


I should note that the old Eudora client was an exception, in that it 
would send a server delete request following successful download of each 
message, rather than waiting until completion of the entire batch.




The solution is to open the truncated message and download the entire
message.  Alternatively, you might be able to view the E-mail server
over the Web and delete the offending message.



If you see this condition only once, yes, making an IMAP connection to 
the server (either by setting up an IMAP connection in your mail client, 
or by going to webmail access, which is also IMAP) will allow you to 
move both the messages you've seen, and the problem message out of the 
inbox (whether to trash, or just to some other folder) so that the top 
of the inbox becomes messages that you haven't yet tried to download.


However, I do concur with the advice that restarting in Safe Mode is a 
useful thing, as that will indicate whether the problem may be either 
with an extension, or some other personal preference setting that may be 
sufficiently amiss that it's interfering with download.
