Yahoo Delivery Problem

Berkeley Parents Network > Help & Frequently Asked Questions > Yahoo Delivery Problem


Oct 31, 2008

We've been notified by yahoo that they have removed the block on BPN newsletters as of today. Good news!


April 2008

For several months, Yahoo has been blocking some BPN newsletters without notifying its customers. BPN has been unable to resolve this despite following Yahoo's procedures for "bulk mail" problems. We recommend that people not subscribe to BPN with a Yahoo address. We suggest using gmail instead, which has not had this problem. More information about this and other delivery problems can be found here: List of Current Delivery Problems.

form letter replying to a trouble report BPN filed.]

April 14, 2008

Hello.
Please understand that I am writing about a mailing list that has been
in operation for 15 years at UC Berkeley -- "Berkeley Parents Network"
(BPN).  The list is run by a computer scientist at UC Berkeley, on a
computer supported by UC Berkeley's IT group. BPN complies with or
exceeds all standard email practices. There are 21,000 BPN subscribers, 
5,000 of whom have yahoo accounts. The other 17,000 subscribers are not 
having this problem, only the yahoo subscribers. There were no problems 
delivering mail to yahoo subscribers until recently, other than delays.

Here is the problem: Yahoo is blocking some of the BPN newsletters,
but not all of them. When a newsletter is blocked, Yahoo is not
notifying its subscribers. It appears Yahoo is blocking newsletters
that have a large number of email addresses in the body.  For example,
our weekly Childcare newsletter contains names and addresses of people
looking for and offering childcare; it is being blocked regularly. 
Other newsletters are not being blocked.

I am getting a lot of complaints about this, because the BPN Childcare
newsletter is the way people find childcare in the East Bay. I am
advising people not to use Yahoo if they want to receive BPN mail, but
to use gmail instead. This is not very good PR for Yahoo in the Bay
Area - it seems like this should be a priority for Yahoo.

To continue to receive prioritized delivery, we recommend ensuring that your email lists are well maintained. If you conform to industry standard practices, then you will not be deprioritized and you should see improvements in delivery times as well as available connections.
