Please reread my message; I don't want to be notified that mail sent to me has bounced, I want the sender to be notified. I want to be notified if mail that *I* sent has bounced.
The person responsible for finding why an e-mail didn't get through is the person that sent it, but that's possible only if the receiving e-mail server sends a proper 5xx response and any relays involved handle it correctly. -- Shmuel (Seymour J.)

Would you really want to get notified for every one if 99.99% were really trash? The solution I want is to diagnose the fate of a single note that I know I should receive but don't. In the case of the missing IBM verification, no one has been able to do that. ;-( . .

Silently dropping e-mail, or moving it to a spam folder, is just plain wrong. The proper way to do filtering is to detect an issue during the SMPT transaction and to send an appropriate message, with appropriate code and sub-code, so that legitimate senders know that they are not getting through and why. Also, of course, any reasonable e-mail client or relay will report the error response upstream, not just ignore it. Alas, there's a lot of broken e-mail software out there. -- Shmuel (Seymour J.)

They never get through from anyone (although someone once said they tried 50 times and eventually one got through). This first raised its head sending from my personal email address to my company email address. When I cornered a Microsoft Exchange guy here he did some checking and said it was being rejected because the email was coming from an origin IP address that was not registered. They had recently added checking to their email system and these failed the check. So, for example, if the email comes from [email protected] then the IP addresses of all the foo.bar email servers have to be registered under the foo.bar name. This is done in the public facing DNS by the owner of the foo.bar domain. I had to go to my personal DNS entry and add the appropriate entry. Since then my emails have got through fine. Fortunately my ISP had a webpage explaining how to add this because it was all new to me. More and more email systems are apparently checking this DNS entry is correct to prevent spoofing. It stops me sending an email pretending to be from [email protected] (for example) as that would originate in my ISP's email server which is not an IP address registered by the owners of microsoft.com. I think I can live with that restriction. If you've never heard of it then read up about SPF (Sender Policy Framework) in Wikipedia. I have no idea who to contact in IBM to check their end. I tried sending some emails (haha) to no avail. We still have problems. I tried sending a password reset email from 'Service Request' to my company email 15 minutes ago and it never got through so the problem still appears to exist. Windows NSLOOKUP (maybe others) will show you the SPF settings for US.IBM.COM (or any other domain). When I checked just now US.IBM.COM has the following specified: "v=spf1 ip4:148.163.158.5 ip4:148.163.156.1 a:d25xlcore010.ca.ibm.com a:isource.boulder.ibm.com a:y01exnat001.ahe.pok.ibm.com a:y01acxsmtp001.ahe.pok.ibm.com a:y01acxsmtp002.ahe.pok.ibm.com a:g01zcdsmtp002.ahe.pok.ibm.com ip4:129.33.239.88" I'm still working on our problem trying to find the correct people to resolve it. At this stage I can confidently say it's either us or IBM!! However, I can say that I just checked the last PMR update email (header) that got through and it came from srdonotreply @ us.ibm.com from IP 148.163.158.5 which is in their list above. Also I sent a password reset to my personal email address and it said it came from ibmacct @ us.ibm.com from IP 167.89.77.139 which is not in their list. I guess my ISP doesn't check (yet). It appears they might outsource this password service hence the problem lies there as that IP address is someone called sendgrid.net. I will keep digging but it is low priority. Anyway, I would advise checking with whoever looks after your email system and ask them to check in their logs as to why the email is being rejected. It might be as above or it might be something else.

After 20 years managing the same userid, I find that there is now a new confirmation process that did not exist a few months ago. I am sent an email to verify my email address. Unfortunately that email never reaches my Inbox. I've tried over and over; it never shows up. A problem ticket with my email folks has not resolved the issue. It's reminiscent of an old problem with IBM Main, where the confirmation email for a new subscription also does not show up. I learned some time ago that just that particular note is lacking a 'Sender' and is therefore treated here as spam. I can't prove it's the same issue with the IBM.COM confirmation, but it smells familiar. Anyone else having issues? . .
