For the record, here is the summary published by Google: http://www.google.com/appsstatus/ir/4et50yp2ckm8otv.pdf
Probably already seen by most people on this list. The relevant piece is: > A configuration change during this migration shifted the formatting > behavior of a service option so that it incorrectly provided an > invalid domain name, instead of the intended "gmail.com" domain name, > to the Google SMTP inbound service. As a result, the service > incorrectly transformed lookups of certain email addresses ending in > "@gmail.com" into non-existent email addresses. When the Gmail user > accounts service checked each of these non-existent email addresses, > the service could not detect a valid user, resulting in SMTP error > code 550.
