Broken SPF Check implementation in Microsoft Exchange Forefront?
by Benoit Panizzon 02 Dec '13

02 Dec '13

Hellou Today, I discovered, that emails whose envelope sender matched the DNS SPF record, but whose From: Header did not (like after the envelope sender has being rewritten by SRS) were rejected by a hosted exchange server provider. I got in contact with that admin and he told me that this was the way the SPF check works in the Microsoft Exchange Forefront Server. Well, according to the RFC 4408 only HELO or MAIL FROM are being considered for SPF. Not the From: header. Is there anyone out there who can confirm, that Microsoft Exchange Forefront Server realy has such a broken SPF implementation. Or did the exchange admin just misconfigure his server?

swinog.ch and SwiNOG meeting
by Tobias Brunner 28 Nov '13

28 Nov '13

Hi everyone, Does anyone know what happened to the website www.swinog.ch? It just serves a "Default Parallels Plesk Panel Page". Looking back at past meeting dates on archive.org it would have been time for another meeting at around November, but I think there was nothing announced. I'm wondering when the next meeting would take place? Cheers and good night, Tobias

Mailserver migration problems with Apple devices
by Michael Richter 27 Nov '13

27 Nov '13

Hi there does anybody have experience with mailserver migration and apple clients. We have no changed the ip address of our mailserver -> we have changed the A Record from mail.xy.ch to a new IP. Since then we've a lot of calls from clients which are unable to receive mails. On the iPhones, the authentication option has gone!!. When the customer set its back to password it's working again. But I had also some OS X Mail which had the right settings, but didn't work. I had to configure the account from scratch. So it's defnitely an Apple "Problem". Does anybody now why this is not working or why the settings are changed from the device itselfs?

Project of cooperation between Swiss ISPs
by Gregory Agerba 23 Oct '13

23 Oct '13

Dear SwiNOGers, This is a short message targeting small and medium Swiss-based Internet Service Providers. A few days ago I started reaching out a few ISPs, mostly in the region of Zurich/Zug/Bern/Basel, to discuss the possibility of a smart collaboration in a “cooperative” and “constructive” way. I actually wanted to check out if there was any enthusiasm on the idea of building together a network to reach major European Internet Exchange, buy Transit in bulk, peer with larger networks and setup a larger DDoS mitigation service. The idea came when I saw that many smaller ISPs deploy the same type of network, seeking the same advantages and struggle to deploy a wider reach outside Switzerland due mostly to a lack of available manpower or financial backing. Amongst a more human collaboration between tenants, various cross-business opportunities, the idea is to collaborate on: - Establishing a privileged network of trusted companies and people - Enhancing IP Transit Connectivity quality and costs by playing on larger value scales - Enhancing IP Peering Connectivity by reaching various European IXs over the same infrastructure - Enhancing campus-interconnection in Zurich by lowering costs for inter-DC connectivity in Zurich (DWDM/DF) by sharing the same infrastructure - Build and share a larger DDoS mitigation platform These challenges are part of day-to-day hassles that every ISPs companies have to deal. Scepticism of a working business-model has been highlighted by various interested parties. Other topics such as IP Transit rates erosion costs vs. high transport costs and port-fees have been thoroughly considered too. Therefore, for Swiss ISPs who are interested and willing to take a look, we’d like to invite you to join our discussion board – www.swissnog.ch – please keep in mind that this is in no means a board affiliated with SwiNOG and that if you want to debate about it you are most welcome to join rather than reply here. We look forward to seeing you there! -- Gregory
