I moved a user's email account, and now cached x500 addresses to the user are failing. How do I translate the x500 in the bounce message to the correct x500 alias I should add to their mailbox?

Bounce text:


Matching x500 address:


I am reasonably certain of the entire translation except that b81 near the end. However this translated x500 address (either with the b81 included or truncated) does not work for getting mail to properly arrive when I add it to the user. Is there documentation (or even better... a copy-paste translator page) on how to reverse engineer the correct x500 to add to the user so that cached account credentials continue to work?

what's the user's mailbox alias? usually the alias is the last CN. – longneck Sep 24 '12 at 16:18
Other than some obscuring of actual names, the code above displays exactly what the mail server returned when it tried to deliver mail to them; while it is not just the CN of the user, it is obviously related to it. The alias for the user is jdoe, and matches the beginning of their primary email address ( Is that what you meant? – Myrddin Emrys Sep 24 '12 at 21:29
I can't quite tell from your original question, but have you tried putting b81 at the end? If it was an escape sequence, it would have a plus sign, so I think it's literal. – longneck Sep 25 '12 at 0:27
You are correct that I did not mention it... but yes, I tried it as a literal, with no result. – Myrddin Emrys Sep 25 '12 at 6:07

After much pain and suffering, our mail admin finally found a translation method that works:

/o=ORGANIZATION/ou=First Administrative Group/cn=Recipients/cn=User

The issue was case sensitivity; the o=, ou=, and other things are case sensitive and the correct case is not always represented in the error. Very frustrating. I hope this helps someone!
