R: [swinog] Urgent: Really Severe Bug in POP3 Pickup Service ofMicrosoft SBS?
by Manuel Wenger 12 Apr '05

12 Apr '05

We've had the same problem with a customer who sent a Merry Christmas email to about 150 of his customers. Of the recipients, 3 of them had the POP3 Exchange Connector which then kept sending the email over and over to all 150 recipients for about 2 weeks. Then they called their sysadmin who flushed the queue somehow and it stopped. Sorry, I don't have a solution for you - this is just to tell you that you're not alone :-) -Manuel -----Messaggio originale----- Da: Benoit Panizzon [mailto:panizzon@woody.ch] Inviato: martedì, 12. aprile 2005 15:59 A: swinog(a)swinog.ch Oggetto: [swinog] Urgent: Really Severe Bug in POP3 Pickup Service ofMicrosoft SBS? This M$ POP3 Connector for Exchange get's the Emails from a POP3 Account, looks at the To: line and delivers them to the recipients found there. Great! Now we have about 5 Servers on the net in Switzerland playing Email-Ping-Pong with each other and filling up the inboxes of those original 50 recipients... :-/ Does somebody know about this Bug or config problem and has a quick fix?

Urgent: Really Severe Bug in POP3 Pickup Service of Microsoft SBS?

Heyo Just had to analyze a quite strange problem of our and a customer's Mailserver being mailbombed... It turned out, that the customer sent an email to about 50 recipients. He put all the Recipients in the 'To:' Line. Shortly after that, his Exchange Server was Mailbombed to death. He called me and I tool a look into our logfiles and noticed a huge amount of entries with his domainname. Mostly from Bluewin and Cybernet. I first tought of a new very heave Virus outbreak, because our Mailserver is not MX nor Backup MX for the customer's Domain. After a closer look I saw that all those mails were addressed to our customers, but arrived from many different IP's @bluewin and @cybernet. The 'From:' line was the customer who originaly sent that email to those 50 recipients. So I connected one pop3 box of a affected customer to have a closer look at the headers. All the mails that keep being resent had all original 'Receive:' lines removed. The oldest one is: Received: from mail pickup service by [$customersserver] with Microsoft SMTPSVC; After talking to the Mailadmin of the Exchange Server, this seams what happens: This M$ POP3 Connector for Exchange get's the Emails from a POP3 Account, looks at the To: line and delivers them to the recipients found there. Great! Now we have about 5 Servers on the net in Switzerland playing Email-Ping-Pong with each other and filling up the inboxes of those original 50 recipients... :-/ Does somebody know about this Bug or config problem and has a quick fix?

Mail bombing...
by Matthias Hertzog 12 Apr '05

Hi folks! Regarding that trouble-ticket, concerning a very well-known issue, i like to get your opinions. http://www.hostpoint.ch/support.php?subCatID=CASU3&mod=det&tid=52 Does anyone of you out there has a "fit for all purpose"-solution to such things? We had a similar attack a few weeks ago and solved it with some additional hardware to open more incoming slots. That worked fine and was a proof for our infrastructure concept. But: Are there better solutions available? Do we really have to add hardware + hardware + hardware while the bandwith on the user's side is continously growing? Best wishes, Matthias

And I don't know what more passes through that box, maybe that is why your email volume suddenly dropped ? :) Greets, Jeroen

WIPO Seminar on Copyright and Internet Intermediaries (fwd)
by Felix Rauch 06 Apr '05

06 Apr '05

This is not of technical nature, but might be of interest to some participants of this list: On April 18 there is a WIPO seminar in Geneva on "Copyright and Internet Intermediaries" (e.g. ISPs). It's supposed to be with experts and audience participation. - Felix WIPO Seminar on Copyright and Internet Intermediaries, Geneva, April 18, 2005 Register online at http://www.wipo.int/meetings/2005/wipo_iis/en/ The Seminar The management of intellectual property in the online environment poses significant opportunities as well as challenges, and raises high stakes as the value of online transactions, both authorized and unauthorized, increases. Internet intermediaries, as providers of services that enable these transactions to occur, are at the center of global debate involving complex policy, legal and business issues. The WIPO Copyright and Related Rights Sector is organizing a Seminar on Copyright and Internet Intermediaries to help obtain a better understanding of these issues. The Seminar will be held in Geneva on April 18, 2005. The Seminar is designed to provide a forum for discussion among international experts and business leaders, academics, government delegates and policy makers. Key speakers, with audience participation, will address various ways to approach issues relating to copyright liability of those who act as online intermediaries: which may include Internet service providers (ISPs), providers of file-sharing services, auction sites and portals. Venue and date The Seminar will be held at the headquarters of the World Intellectual Property Organization (WIPO), 34, chemin des Colombettes, 1211 Geneva 20, Switzerland. It will run from 9 a.m. to 5 p.m. on April 18, 2005. Participants should arrive before 8.30 a.m., in order to complete their registration. Registration The Seminar is open to all interested persons, free of charge, although numbers will be limited by seating capacity. Those wishing to register are requested to return the registration form <http://www.wipo.int/meetings/2005/wipo_iis/en/registration.html>. -- Felix Rauch, http://www.nice.ch/~felix/ Member of Swiss Internet User Group (SIUG): http://www.siug.ch/ This article contains my personal view only!
