Huge retry delays in mail from Sunrise
by Stanislav Sinyagin 27 Mar '07

27 Mar '07

hi, We use the email greylisting policy for incoming email for us and our customers, and it appears that often the email from Sunrise network comes with huge delays, from several hours to several days. Did anyone else see such problems? Guys from Sunrise, plase contact me directly for more details and troubleshooting. Such delays seen in email coming from smtp-auth-be-01.sunrise.ch (mail-proxy-be-01.sunrise.ch [194.158.229.48]) smtp-auth-be-06.sunrise.ch (mx-auth.sunrise.ch [194.158.229.90]) cheers, stan 044 732 9953 079 407 0224

MPLS VRF source routing (inter-vrf routing)
by Steven.Glogger＠swisscom.com 22 Mar '07

22 Mar '07

hi all i've got some nice cisco bugs / features / whatever. some prerequisites: - 2 VRFs: vrf blue and vrf red - both vrfs have a different default route. - a PPP session / user terminating in vrf blue a specific route (10.0.1.0/29) is routed over static route (e.g. radius avpair) over the ppp session (vrf blue). this route is imported to vrf red by importing rd values and route-map filtering. so the connectivity from the red vrf to the vrf blue is working (one way). so, the goal (and this is the problem) is traffic souring that specific route should go back to vrf red. how i thought would be the simplest way to do it: policy routing. interface virtual-access123 ip policy route-map set-vrf-red ... ! access-list 110 permit 10.0.1.0 0.0.0.7 any route-map set-vrf-red permit 10 match ip address 110 set vrf red ! would be the nicest way of doing this. now the but: if you put the policy on the virtual-template / radius profile the session starts flapping (connect/disconnect/connect/disconnect....). so: not usable. my other approach was: interconnect vrf blue with vrf red by a vlan / interface. assume on vrf blue: fastethernet0/0 with 11.0.0.1/30 connnected to vrf red with fastethernet0/1 with 11.0.0.2/30. modifying the route map to: route-map set-vrf-red permit 10 match ip address 110 set interface fastethernet0/0 set ip next-hop 11.0.0.2 ! this will stop the flapping (disconnect/connect/disconnect...) of the ppp session and the whole routing works as expected.... BUT: somewhen it stops working because of one thousand possible CEF bugs ;-( i have to put "no ip route-cache cef" on the interconnection interface, then it works. some hours later (as already said) it stops working. when i do again "no ip route-cache cef" on the interface it works some other hours. i've tried several IOS for the C7200series and the only half-way working version is the 12.4T (or even 12.3T). so, now the big question to the community: 1) do you see any other working way doing source-routing from one vrf to another vrf? (there's a vrf source routing command, but i think this will really not scale) 2) do you have encountered the same CEF bugs? (i have seen them on 7206, 1841 and 2851 series routers) how cisco tells me to do it: http://www.cisco.com/en/US/products/sw/iosswrel/ps1838/products_feature_ guide09186a0080296409.html i would be glad to get some input from you guys. greetings -steven

Swisscom wants CHF 31/Month per regulated copper line
by Andre Oppermann 21 Mar '07

21 Mar '07

The price seems to be a bit far out when considering that a normal phone line (which includes the telephony infrastructure as well) costs only CHF 25.25/Month. Reading the financial reports of Swisscom from the last few years it doesn't seem Swisscom was losing any money on the phone lines even when excluding any traffic minute charges. http://www.swisscom.com/GHQ/content/Media/Medienmitteilungen/2007/20070320_… Yet more work for BAKOM, Comcom and the Bundesgericht in the next years. -- Andre

Any others having troubles with mails being rejected by: mail-fwd.mx.hostcenter.com
by Benoit Panizzon 17 Mar '07

17 Mar '07

Hi all Since Weeks we steadily get complaints from different customers (sometimes sending mail via our server, sometimes with own servers, sometimes using mailservers of other ISP) trying to send email to Bluewin Hostcenter Customers. Their emails are being rejected by mail-fwd.mx.hostcenter.com. The message from the Hostcenter Server ist: (reason: 554 Denied) What I have found out since is: The Recipient uses the Hostcenter's anti-spam Solution. This is a 'blackbox solution' operated abroad, the Hostcenter Techs have no access to logfiles and there is not tech support abroad for that solution which could look into logs to tell what goes wrong. It is impossible to find out why an email was rejected. So the only thing I can tell our customers is: It's not working because the recipient is using a anti spam software which does not like your emails. Please communicate via fax or letter, just accept that email is not working and that we cannot fix it because the problem is at mail-fwd.mx.hostcenter.com and not our mailserver. But the customers of course keep blaming us, because our server is 'not able to send mails to mail-fwd.mx.hostcenter.com'. I wonder, are we the only ISP which gets this many complaints about emails not being accepted by mail-fwd.mx.hostcenter.com or are others also affected?
