work great!!!

I appreciate your getting back to me with this although it didn't work for me. The title and notification show one sender and the PM itself another. Regardless would it be possible to include some kind of logic to check what the user's settings are and not make any changes (or send notifications) if they've already been processed in order to avoid accidental spamming?

Anyway thanks for this, you've allowed me to deal with about 500 members who's bounces have been bothering me...

hugh

I don't quite understand what you mean. Are you saying that when you open the PM, the sender is different then what shows in the popup "you have received a new private message from {1}" phrase?


If the user has already been processed, then the change in settings would prevent any further emails going out to them, unless you're sending emails with "include users who have not chosen to receive emails from admins" checkbox. You can't send to those members otherwise you defeat the entire purpose of this modification.

I'm currently not allowing registrations with Yahoo e-mail addresses on my site because of problems that Yahoo e-mail adresses caused on my site/server in the past, notification bounces etc. that got so bad that it affected the performance of my server.

Now that I'm using EZ Bounce I'm wondering if I can start to allow Yahoo registrations again. I'm not too keen on allowing Yahoo again, but I know that there are lots of people who only use Yahoo and who are not registering on my site now. What do you think? Can I allow Yahoo again now that I use EZ Bounce? I set up a seperate Bounced usergroup for EZ Bounce so as long as I'm not e-mailing to that usergroup and perhaps empty that usergroup once in a while I should be safe?

Is there anyone here who has a site with many users (10.000 +) who does allow Yahoo registrations? How is it working out for you?

Thanks.

I cant see how Yahoo is any different to Gmail , Hotmail or anything else. I have a 60,000 member site and allow any email addresses. If you force people to use their provider email address , you will end up with a lot more dead emails because people lose the address as soon as they change provider. People with Yahoo , Homail , Gmail etc are more likely to keep the accounts permanently.

The issue I have found is that recently (within the past 2 months or so) Yahoo has begun using graylisting on all email received. I'm no expert on this stuff, but my understanding is that graylisting will bounce every email received once, and give the following reason:

Reason: Remote host said: 421 Message from (66.252.232.90) temporarily deferred - 4.16.50. Please refer to http://help.yahoo.com/help/us/mail/defer/defer-06.html

Basically what this does, is bounce the message back, and when the sending mail server receives it, it retries the message within 10 minutes. Upon the second receipt, yahoo's servers will allow it to pass through, then based upon the recipient's settings it will either end up in their inbox or junk folder. The premise of greylisting is that spammers rarely resend bounced spam email from their automated programs, so it does indeed significantly reduce the amount of spam received.

The problem which you're experiencing (i think all php applications using mail_send() experience this- not just vbulletin) is that php's mail_send() method of generating automatic emails currently has no method to know to resend the bounced emails from yahoo with the 421 error in the header.

I tried a workaround for this by changing the method by which email is sent to use SMTP instead of mail_send() which should fix the problem with yahoo bounces, and I get significantly less bounces from yahoo, but on occasion I still do receive 421 bounces from yahoo. I think that the main issue is to make sure your hosting company treats SMTP connections from your vbulletin scripts with the same permissions as from you when connecting through your ISP.

so what now?

Q: What now?
A: Check the reason for the bounced mail before clicking on the EZ-Bounce link. I don't use this for deferred delivery or mailbox full errors - only for nonexistent or closed mailboxes.

So how do i set it?

Exactly what djbaxter says, don't click ezbounce link in email headers for emails that have bounced due to "deferred delivery" OR "mailbox full" as they are in reality soft bounces.
