Email to domain yahoogroups.com being delayed and visible in Sys Manager Queues in Exchange 2003

Hey All,

I have asked similair questions and this problem keeps taking turns. A little background:

Early febuary, we were using an open relay for 3-5 of our users who were using POP3 accounts. Our E-mail server was being used to send SPAM by outside sources so we closed down the open relay and mandated they all being on Exchange accounts. We were inadvertantly put on Yahoo's black lists and were unable to send any mail to people with Yahoo accounts. We requested our Domain be removed by submitting our IP (after closing the relay) and all was working great.

We did not think to check Yahoogroups.com (assuming they use the same blacklists) and have not been able to send E-mail to email addresses at yahoogroups.com. Our exchange server is set to try to deliver the messages in Queue 3 times, to e-mail delivery delay after 12 hours and deliver failure to deliver after 24. Here is what we get:

12 hours: This is an automatically generated Delivery Status Notification.

THIS IS A WARNING MESSAGE ONLY.

YOU DO NOT NEED TO RESEND YOUR MESSAGE.

Delivery to the following recipients has been delayed.

Subject: RE: Please respond!
Sent: 3/28/2006 5:36 PM

The following recipient(s) could not be reached:

phialphaluc@yahoogroups.com on 4/1/2006 9:54 AM
Could not deliver the message in the time limit specified. Please retry or contact your administrator.
<LEVERE.SAE.net #4.4.7>

Additionally, in looking at the Queues in System Manager, we find the messages in the queues, some messages listed as Retry others listed as Delayed.

We have Exchange 2003 server using GFI for SPAM monitoring (in house on the exchange server). We can e-mail essentially everyone else without problem, but in looking at the queues, nothing is being sent out to the Yahoogroups.com domain. Server is Virus/Spyware free (Symantec Corp 10.0)

What's the problem here and who is it with. It seems that our domain cannot connect to the yahoogroups.com domain to deliver mail, which I assume is why the mail is being held in the queues.

If it's a problem with us, where can I look to get it resolved. If it's a problem on Yahoo's end, what can I send them to show that they are blocking our domain.

Please help!

Lets see if it is an issue with your server.

Login to your Exchange server.

Goto Command prompt START/RUN/CMD/OK

type the following:

C:\>nslookup
Default Server: dhcp26.fileset.net
Address: 105.25.26.33

> set type=mx
> yahoogroups.com
Server: dhcp26.fileset.net
Address: 105.25.26.33

Non-authoritative answer:
yahoogroups.com MX preference = 1, mail exchanger = mta5.grp.scd.yahoo.com
yahoogroups.com MX preference = 1, mail exchanger = mta6.grp.scd.yahoo.com
yahoogroups.com MX preference = 1, mail exchanger = mta7.grp.scd.yahoo.com
yahoogroups.com MX preference = 1, mail exchanger = mta8.grp.scd.yahoo.com
yahoogroups.com MX preference = 1, mail exchanger = mta9.grp.scd.yahoo.com
yahoogroups.com MX preference = 1, mail exchanger = mta10.grp.scd.yahoo.com
yahoogroups.com MX preference = 1, mail exchanger = mta1.grp.scd.yahoo.com
yahoogroups.com MX preference = 1, mail exchanger = mta2.grp.scd.yahoo.com
yahoogroups.com MX preference = 1, mail exchanger = mta3.grp.scd.yahoo.com
yahoogroups.com MX preference = 1, mail exchanger = mta4.grp.scd.yahoo.com

yahoogroups.com nameserver = ns4.yahoo.com
yahoogroups.com nameserver = ns5.yahoo.com
yahoogroups.com nameserver = ns1.yahoo.com
yahoogroups.com nameserver = ns2.yahoo.com
yahoogroups.com nameserver = ns3.yahoo.com
mta3.grp.scd.yahoo.com internet address = 66.218.66.218
mta5.grp.scd.yahoo.com internet address = 66.218.66.166
mta7.grp.scd.yahoo.com internet address = 66.218.67.33
ns1.yahoo.com internet address = 66.218.71.63
ns2.yahoo.com internet address = 66.163.169.170
ns3.yahoo.com internet address = 217.12.4.104
ns4.yahoo.com internet address = 63.250.206.138
ns5.yahoo.com internet address = 216.109.116.17

> exit

Then use the hostname that showed up in MX preference one, in above example it was mta5.grp...

C:\>telnet mta5.grp.scd.yahoo.com 25

You should see a screen saying something like 220 ............

If you see the screen then try to send a text message and see if it works.

Following the instructions in following KB to test it.

I think i replied the same to another question you posted elsewhere.
Yahoo.com and yahoogroups.com have different email servers. When yahoo blocked you they would have replicated the domain to be blocked on all yahoo servers. Contact the same yahoo support people and inform of the issue. Or post a new support request via yahoo groups help.

naveedb: I did as proscribed, but after I attempt to connect, I get a blank Command prompt and the reverts back to C:\windows\

No 220 connection... please advise.

When you do nslookup, what do you see as host with MX 1 preference?

Can you post your output when you ping the MX 1 address?

just to make sure that telnet is not blocked for you, please telnet a domain or IP of an address you can indeed send emails out to.

Just in case.

I still think that yahoogroups would not have removed you entirely but just to make sure....

upul007

In exchange server > Sustem Manager > Queues - at the bottom of the window you get Additional Information and a breif description appears. After a mail had been sent to yahoogroups, in the queue highlight the yahoogroups queue and see what the additional info says. please post that info here as well.....

System Manager for Yahoogroups: The remote server did not respond to a connection attempt

Patrick

You should also know that I have been going back and forth with Yahoo asking them to replicate it and they keep sending form letters asking for more information. Very recently, they had me submit information about Bulk Mail, which has NOTHING to do with the problem and told me that they are sorry but we appear to have sent a lot of SPAM in the past few weeks and to try again in the next 6 months.

"The remote server did not respond to a connection attempt" - I get this all the time when our domain is blocked or for some reason that domain does not exists or even the user. Please recheck the yahoogroups address again to make sure that it is valid.

naveedb advice (c) is also ideal.

When we got listed what we did was to completely change our static IP to another one through our ISP. We had 0% mail loss as our back up mail servers were collecting the emails until the change occurred and there was only a small configuration change to be done on the firewall. I do not know if this is feasible for you.

If you know any Yahoogroups moderator (you can become one as well if you really want to), you could get them to complain to yahoogroups about this. Other than that you need to be very very patient sometimes with webmail folk to get things done.

Cheers!

I would suggest a 50-50 split with naveedb as he had put good advice and placed considerable effort on helping to resolve the issue.
