Microsoft mail delivery issue

[Paul Kelly - Blacknight]

Hi There,

If there are any Microsoft mail admins on the list can they please contact me 
ASAP. We’re having deliverability problems into you and all the usual tools 
don’t help with fixing problems, only diagnosing them after the fact.

Thanks,

Paul

Hi there,

Could someone who looks after the email for General Motors please contact me 
off list?

Some of our customers are experiencing bounce backs sending you emails and it 
looks like it’s DNS related.

Thanks,

Paul

RE: Outage between GBLX and HE?

[Paul Kelly :: Blacknight]

It looks like it's back now. I was seeing spotting US connectivity via GLBX 
upto 08:57 GMT.

Hey All,

Sorry to bother the list, but I'm noticing that I've got no connectivity to 
Hurricane Electric through GBLX from my Qwest DSL.

In this case, I'm trying to get to tunnelbroker.net:

...

Testing out through the T1 which goes via twtelecom works fine, as does from 
co-loc in Seattle which goes through Integra.

Don't suppose anyone else is noticing this as well?

yahoo mail admin(s)

[Paul Kelly :: Blacknight]

Hi There,

Could a yahoo.com mail admin contact me offlist please? We get calls from 
customers saying that e-mails from their yahoo.com e-mail address to us bounce 
back due to a DNS lookup issue.

The issue seems intermittent but it's at a level that is sufficient enough to  
raise some eyebrows by the head of our customer service team.

Cheers,

Paul

In theory Maxmind is quite accurate. From 1 x /20 that we own we tag different 
space with the country: flag in the RIPE db. Maxmind picks this up after approx 
30 days and says it's in Country X vrs country Y.

e.g.

$ geoiplookup 81.17.247.64
GeoIP Country Edition: US, United States
$ geoiplookup 81.17.247.1 
GeoIP Country Edition: IE, Ireland

Obviously the RIPE db structure makes this simple. As for other RIRs it's not 
as easy. Like someone else said, it's going to be an 80% solution and its 
really down to good administration from a network operator point of view. i.e. 
if you route some of your RIPE space in ARIN territory you should specify the 
country. There's numerous reasons for this but it's just good practice IMO.

Google / Gmail SSL write errors

[Paul Kelly :: Blacknight]

Hi All,

Are any of you (that use Exim as their MTA) having SSL write errors in your 
exim logs when delivering e-mail to Gmail or Google addresses?

it seems limited to Exim as we've got a lot of other MTAs that have no issues. 
it also appears to be specific to emails with attachments...

Anyone aware of changes G have made regarding TLS delivery?

Ta,

Paul

RE: Cisco interface - GB of transfer software

[Paul Kelly :: Blacknight]

MRTG + GBGraph + 95th.pl allows for MB/GB/port/vlan and also 95th percentile on 
same.

It doesn't take much to build a small report that picks up on the files left 
behind by 95th.pl and GBGraph.

Outblaze admins?

[Paul Kelly :: Blacknight]

Hi There,

If there are any people who manage outblaze can they contact me either on or 
offlist. We've been trying to get a server delisted since September 12th and 
have been completely unsuccessful. The website doesn't appear to remove the IP 
and using the contact forms to contact the postmaster has not resulted in any 
contact from them to us.

Thanks,

RE: McColo and SPAM

[Paul Kelly :: Blacknight]

We saw a dramatic decrease. Attached is our dnsbl mirror in .ie, it mirrors 
spamhaus amoungst other things.

The numbers are in 1000s of 1000s per 5 minute window. (so 2500k = 2.5m)

You can see a dramatic decrease that corresponds with them going offline and 
then the spam level gradually coming back, but it's certainly not back full 
tilt yet.

We experienced exactly no decrease with the McColo shut down a few weeks
back, even though we receive 2M+ messages per day.  It's interesting that
each service provider's spam populations are as different as they are.  Some
experienced gigantic decreases, others didn't.  And it's not like we have
just one domain.

I know MessageLabs examines spam rates per industry type.

RE: McColo and SPAM

[Paul Kelly :: Blacknight]

The reason for that is our legit e-mail traffic pattern I guess. We probably 
see the same level of spam 24/7 but from 8am to 8pm GMT we'd get a lot of legit 
traffic from the few 100k pop3/imap/smtp users we have and as such you'd see 
the peaks and troughs caused by their usage.

Primarily they'd be Irish, but we'd have 10% or so in the UK/Rest of Europe 
aswell, so they'd fit in with the 8-8 peaks.

RE: Gigabit speed test anybody?

[Paul Kelly :: Blacknight]

Hi Rick,

Try an anon ftp or http download from http://ftp.heanet.ie The cluster that 
serves for ftp.heanet.ie has multiple machines with at least single or bonded 
10GE interfaces into HEAnet's backbone and then minimum of 10GE on two carriers 
to the general internet.

Should give you a pretty good speed test. I can max out our GigE links using 
them for testing.

Intrustion attempts from Amazon EC2 IPs

[Paul Kelly :: Blacknight]

Hi there,

Have any of you recently noticed a lot of ssh scanning coming from amazons EC 
"cloud" IP blocks?

Today alone I've seen approx 4m attempts from EC2 IPs on just 20 nodes on our 
network.

Has anyone any experience with Amazons abuse people?

RE: Line rate gigabit router/switch options

Hi Matthew,

The Juniper J6350 boxes are both cost effective and are claimed to do line

We've several deployed between multitple DCs in Dublin and a load of J4350 at

Yahoo! mail admins?

[Paul Kelly :: Blacknight]

Hi There,

Are there any Yahoo! e-mail admins on the list? We're having some issues at 
times delivering e-mail to yahoo.co.uk and sometimes some of the other yahoo 
networks.

Thanks,

Paul
