Yahoo Mail Delivery Issues
by Dominic Schlegel 17 Sep '19

17 Sep '19

Hi All We are experiencing problems delivering mails for domains having their MX record set to mx-eu.mail.am0.yahoodns.net (for example yahoo.it, yahoo.de, yahoo.co.uk). So far we have figured out that Yahoo’s DNS servers send different responses. Depending on the DNS response we are able to establish SMTP connections. Below example shows 2 servers from their DNS that seems to accept SMTP connections: [root@x1:~] # dig a mx-eu.mail.am0.yahoodns.net @yf2.yahoo.com +short 188.125.72.73 188.125.72.74 [root@x1:~] # telnet 188.125.72.73 25 Trying 188.125.72.73... Connected to mtaproxy1.free.mail.vip.ir2.yahoo.com. [root@x1:~] # telnet 188.125.72.74 25 Trying 188.125.72.74... Connected to mtaproxy2.free.mail.vip.ir2.yahoo.com. On the other hand we sometimes get other replies from the “same” (the id.server chaos record tell’s us it’s a different one) DNS server with different A records that do not accept SMTP connections: [root@x1:~] # dig a mx-eu.mail.am0.yahoodns.net @yf2.yahoo.com +short 188.125.73.87 212.82.101.46 [root@x1:~] # telnet 188.125.73.87 25 Trying 188.125.73.87... telnet: connect to address 188.125.73.87: Operation timed out telnet: Unable to connect to remote host [root@x1:~] # telnet 212.82.101.46 25 Trying 212.82.101.46... telnet: connect to address 212.82.101.46: Operation timed out telnet: Unable to connect to remote host We have so far confirmed this behaviour from different AS (Hetzer, OVH). Does anybody else experiencing the same behaviour? We have tried to contact their postmaster address and few others we found on the internet. Unfortunately so far no one was really able to help us. The Yahoo Small Business Phone Number that has been posted on this list back in October 2009 seems no longer to be in operations too. Therefore if you know how to get in touch with their technical staff that would be much appreciated. Best Regards Dominic Schlegel

openssl 1.1.1c and too short DH key on @bluewin.ch
by Benoît Panizzon 17 Jul '19

17 Jul '19

Hi List If you also noticed emails not being delivered anymore to @bluewin after uprading to Debian Buster or and other system with newer openSSL libraries. This is due to new versions of openSSL not accepting DH keys shorter than 1024 to counter the logjam attack. Unfortunately the keys provided by bluewin are too short, causing the TLS handshake to fail. Work-Around for now: Disable DH Test with: # openssl s_client -cipher 'DEFAULT:!DH' -connect \ mxbw.lb.bluewin.ch:smtp -starttls smtp In sendmail.mc O CipherList=HIGH:!DH -Benoît-

Call for presentations and RIPE 79
by Franziska Lichtblau 15 Jul '19

15 Jul '19

Dear colleagues, Please find the CFP for RIPE 79 below or at: https://ripe79.ripe.net/submit-topic/cfp/. The deadline for submissions is *16 August 2019*. Please also note that speakers do not receive any extra reduction or funding towards the meeting fee at the RIPE Meetings. However, on an individual basis, participants can apply for a RIPE Fellowship or RACI, see the "Speakers" paragraph in CFP for more information. Kind regards, Franziska Lichtblau RIPE PC Chair https://ripe79.ripe.net/ripe-pc/ ---------------------------------------------------------------------------- Call for Presentations A RIPE Meeting is an open event where Internet Service Providers, network operators and other interested parties get together. Although the meeting is mostly technical, it is also a chance for people to meet and network with others in their field. *RIPE 79 will take place from 14-18 October in Rotterdam, The Netherlands* The RIPE Programme Committee (PC) is now seeking content proposals from the RIPE community for the plenary sessions, BoFs (Birds of a Feather sessions), panels, workshops, tutorials and lightning talks at RIPE 79. See the full descriptions of the different presentation formats: https://ripe79.ripe.net/submit-topic/presentation-forma ts/ Proposals for plenary sessions, BoFs, panels, workshops and tutorials must be submitted for full consideration no later than *16 August 2019*. Proposals submitted after this date will be considered depending on the slots still available in the programme. The PC is looking for presentations covering the topics of network engineering and operations, including but not limited to: - IPv6 deployment - Managing IPv4 scarcity - Data centre technologies - Network and DNS operations - Internet governance and regulatory practices - Network and routing security - Content delivery - Internet peering and mobile data exchange - Connected Things (aka. Internet of Things - IoT) _____________________________________________________ Speakers _____________________________________________________ Presenters, RIPE Working Group Chairs and the RIPE Programme Committee are required to cover their own costs to attend a RIPE Meeting (meeting ticket, travel and accommodation). We have various ticket options available depending on your needs. Please note that participants can apply for a RIPE Fellowship or RACI, on an individual basis, to develop their professional or academic career. For more information, please visit: https://www.ripe.net/participate/ripe/ripe-fellowship https://www.ripe.net/participate/ripe/raci In extraordinary circumstances, the RIPE Chair can waive the meeting fee for presenters. These requests are dealt with on a case-by-case basis via pc(a)ripe.net. _____________________________________________________ Submissions _____________________________________________________ Presenters should be clear on whether they wish to submit a presentation for a plenary or working group (WG) session. At present, most working groups will solicit policy proposals, discussion points or other content directly via their mailing lists. If you’re not sure what kind of session you should be presenting at, please visit: https://ripe79.ripe.net/plenary-or-wg/ RIPE Meeting attendees are quite sensitive to keeping presentations non- commercial, and product marketing talks are strongly discouraged. Repeated audience feedback shows that the most successful talks focus on operational experience, research results, or case studies. For example, presenters wishing to describe a commercial solution should focus on the underlying technology and should not attempt a product demonstration. Presenters should indicate how much time they will require. In general, the time allocated for the different presentation formats is as follows: - Plenary presentations: 20-25 minutes presentation with 5-10 minutes discussion - Tutorials: up to two hours (Monday morning) - Workshops: one hour (during evening sessions) to two hours (Monday morning) - BoFs: approximately one hour (during evening sessions) - Lightning talks: 10 minutes in total for both the presentation and any discussion The following general requirements apply: - Proposals must be submitted using the meeting submission system, https://ripe79.ripe.net/submit-topic/ - Lightning talks should also be submitted using the meeting submission system (https://ripe79.ripe.net/submit-topic/) and can be submitted any time up to and including the meeting week. The allocation of lightning talks will be announced on short notice, in some cases on the same day but often one day prior to the time slot allocated. - Presenters who propose a panel or BoF are encouraged to include speakers from several (perhaps even competing) companies and/or a neutral facilitator. - All presentation proposals will only be considered by the PC if they contain at least draft presentation slides (slides may be updated later on). For panels, proposals must contain a clear description, as well as the names of invited panellists, presenters and moderators. _____________________________________________________ Diversity and Inclusion - On-Site Childcare and the RIPE _____________________________________________________ Meeting Code of Conduct _____________________________________________________ Did you know that RIPE Meetings now have on-site childcare? You can reserve a spot for your child (age 6 months - 10 years) during the registration process for the meeting. Childcare places are limited, so please be quick to reserve a spot for your child while registering for the meeting. More information at: https://ripe79.ripe.net/on-site/on-site-childcare/ Ensuring that RIPE Meeting values are upheld and that attendees experience a professional, respectful and safe meeting is a priority. Please do read the RIPE Meeting Code of Conduct: https://www.ripe.net/participate/meetings/ripe-meetings/ripe-meeting-code-o… _____________________________________________________ If you have any questions or requests concerning content submissions, please email pc(a)ripe.net. -- Franziska Lichtblau, Forschungsgruppe Internet Architecture (INET) Max-Planck-Institut für Informatik, Campus E14, 66123 Saarbrücken E1 4 - Raum 514 fon +49 681 9325 3514 mobil: +49 176 63897173 gpg-fp: 4FA0 F1BC 8B9A 7F64 797C 221C C6C6 2786 91EC 5CD5
