[Resolved] Mail partially down?

Recommended Posts

Hi.

I can't seem to pop my email from pop.spamcop.net today. Is this a known problem at the moment?

My mail client connects, and see 6 new mails. But while retrieving the first one, the transfer stalls. When I log the network traffic with Wireshark, I see corrupted packets (checksum errors and sudden binary garbage in the data, where plain text should have been), packet loss etc. I see the same at port 80 when trying to load the news page: http://mail.spamcop.net/news.php. Not surprisingly, as it is the same server (216.154.195.50) as far as I can tell.

Webmail and spam reporting (mailsc.spamcop.net) works fine.

Am I the only one experiencing this?

It's a little over one hour since your post and I was able to POP my spamcop account without any problems, but yesterday morning it failed to work for me as well. It may be an intermittent problem. Not sure if they are doing any load balancing or not, if so it might be a server specific problem.

I'm not a spamcop mail user, have you tried clearing out the mail and starting over? Just thinking if the database or links have gotten corrupted, this may clean things up.

I've tried to clean out all waiting mails now. Some mails actually got through, like the notification mail from this forum, so it might be one of the other mails screwing things up. Time will tell.

However, that wouldn't explain the trouble reading the news webpage.

Well, that wasn't it. I am still having problems.

Have you tried any network testing? I am not seeing any issues, and when there is a major problem, this board starts getting busy, which has not happened.

Hmmm - you guys are a fair ways apart. Using http://azero.dk/support/vaerktoej/traceroute/default.asp for something a little closer to the O/P:

... which looks to be working okay (just had the thought there could be some trunk issues but it seems not).

Have you tried any network testing?

Yes. Neither ping nor traceroute reveal anything abnormal. I have no packet loss.

Just loading the news.php page is problematic (and with the lack of emails in my inbox, that test will have to do for now). Here is a Wireshark capture file of the network traffic:

Not sure just how many folks here will be willing to play with an indeterminate .ZIP file.

The "hangs on an e-mail transfer" can usually point to a corrupted e-mail. One could set up an IMAP connection to take another shot at retrieval, pehaps deletion.

Can't confirm the issues with the 'news' page using multiple browsers, OSs, etc.

Wireshark and network analysis are beyond me, unfortunately.

[on edit - .pcap file type 'inside' - I suggest not many would have the viewer, file type might conceivably undermine reliability of security scans.]

Of course you shouldn't trust an unknown file. I just thought Wireshark (former Ethereal) was more widely known, especially among people that are no strangers to network analysis and troubleshooting.

Anyway, this morning all problems are gone. Email coming through and I can also load the news.pgp page fast and reliably every time i refresh the page. I have no idea what happened yesterday, but as this isn't a more widespread problem, I'd guess it was network problems somewhere near my end.

No problem with the knopwledge and use of various network tools, including your choice. As above, I simply stopped when faced with a .ZIP file. Three systems already tasked beyond limits, dozens of open windows/applications running, connected directly to three other mnetworks/systems, etc. .. downloading a .ZIP with unknown content and opening it up is simply is not in the cards under those conditions. (noting that hours later, the only thing that's changed is a few different windows, and currently connected to different networks, working other issues.)

Tagged as Resolved. Glad somebody in the middle apparently solved the network traffic issues.

Oh, that was just to ensure everyone could download the file intact. I have had problems in the past, where unknown file types (unknown to my webserver that is) would get corrupted if downloaded with certain webbrowsers. In hindsight, I probably should have provided the .pcap file instead, and ensured that it had a suitable mime type on the server.

But, problem solved, and that is all that matter.
