Yahoo SMTP Server: Delivery Temporarily Suspended

Recently the outgoing messages to Yahoo from my Linux boxes are all deferred. The linux box hosts a website which contains a webform, which sends about 200 mails to 100 subscribed accounts, which is about 20K messages per day. About 13 accounts are Yahoo addresses. I use Postfix and below is the results from “mailq”.

(delivery temporarily suspended: lost connection with[] while performing the HELO handshake)


Tried to telnet to port 25 of Yahoo’s SMTP server, and this is the message:
421 4.7.0 [TS02] Messages from temporarily deferred –; see
Connection closed by foreign host.
Contacted Yahoo using two online forms:

1. Yahoo! Mail Delivery Issues Form

2. Yahoo! Mail Bulk Sender Form

I submitted the form On Sunday, got reply from Yahoo for the second form on following Tuesday. Here is the response:

Checked the server, the mails are still deferred and total number of mails in the mailq is still rising.

So I followed up with Yahoo using the first form again, with the incident ID I got earlier. Got response within 3 hours:

Thank you for contacting Yahoo! Mail.

We have reviewed the IP information you have provided and made the appropriate changes in our database. As a result, the recent deferrals you have referenced in your report should now be resolved.

After getting this mail, I checked the server and half of the queue has been cleared (about 3500 messages were sent).

Westinghouse LCD Monitor L2410NM HDMI issue

My Westinghouse LCD Monitor was working fine with my old computers on VGA port until I got a new Dell XPS 8500 with Nvidia GT640 video card. I tried to use the HDMI because of my I hate the extra adapter converting DVI to VGA. The image through HDMI looks horrible on L2410NM. The color is washed up.

I googled around and realized it is the monitor’s fault for not giving correct EDID. Someone on has a smart solution without messing up with the video card’s driver. It is a Windows Registry change:

Hey here is the fix, it works this way without editing the driver inf file and it works in Vista and Win7. I don’t know if it works in XP.

Run Regedit & Navigate to:


Open the folder & check each folder (eg. HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Video\{E 0CC2030-CCD8-49B9-8267-83140EF868CB} )

Check each sub folder called “0000” until you come across one which expands and includes the following:


Once you’ve located this, right click the “0000” folder and select “New” followed by “Binary Value”.

Rename the value to:


and hit enter or okay

Next up, you need to right click the new key and select “Modify Binary Data” from the list.

Enter in this info below:
5c 85 80 51 00 00 ff ff 04 00 00 00 7e 01 00

After you enter the info in the value will show as (invalid DWORD (32-bit) value) but this is correct. Reboot and your monitor will work once again. BTW you will need to do this after every driver installation. I have experienced some severe blanking and weird noises from the monitor after some driver upgrades. You might want to connect up the VGA when updating drivers.


Yes, it worked for me. Note this solution is only for this exact model of monitor.

SharePoint 2010 Sent To: E-mail a Link not working

One of our SharePoint 2010 sites has an issue that “E-Mail a link” not working for the documents. This feature is to allow users to conveniently send out a link to a document on SharePoint, by click the dropdown menu of the file.

Did some research and found out it was caused by the masterpage. We upgraded our SharePoint site from SharePoint 2007 to SharePoint 2010, but the look and feel is still SharePoint 2007. We have not performed the Visual Upgrade yet. In other words, we are still using the V3 masterpage. And this masterpage has been customized before.


Use SharePoint Designer to open the customized default.master. Add the following code into <HEAD></HEAD>

   <SharePoint:SPPageManager runat=”server”/>

Save the file and go back to your site. Try the function again.

Managed Property does not filter PDF, DOCX, DOCM, JPG files

We have two simple scopes defined based on a field called “status” for the files in a document library. The field value is either “Active” or “Archived”.

User complains she couldn’t find a document in the “Active” documents scope. That document was indeed set “Active” in the status field. This document is a Microsoft Office 2010 version word document ending with “.docx”. I tried to do another search for a “Active” PDF document and couldn’t find it in the search result either. Same thing happens for “DOCM” and “JPG” files. “DOC” and “XLS” files work just fine.

Also if I search the document in site level, they do show up in the results. that means they are being indexed.

I looked at the scope definition and found there are 597 documents in the scope. However I can see there are 635 documents in the document library marked as “Active”. The difference is the total count of those non-Office 2003 documents.

I tried to removed the rule of “Managed property” from the scope and leave another rule (folder based rule), and the document shows up in the results.

Based on the above facts, I suspect there is something wrong with managed property. Did some googling using keywords “Managed Property PDF” and located this page:

“On further investigation, we found that the particular column with the issue was a “Date and time” type column. However, the managed property had been mapped to a crawled property with the correct name “Date of origination” but of type “Text”. This mostly worked, but not for pdf files. When we re-mapped the managed property to the crawled property with the name “ows_Date_x0020_of_x0020_origination” and type “Date and Time”, and did a fresh full crawl, it worked correctly.”

It was exactly what happened to me. I went into the managed property and tried the mapping again. Added “ows_Status” as the new mapping. Performed a full crawl. Problem went away.
