Prior to April 2023, we ran a daily routine that collected invalid email addresses throughout the day, then during BOD processing marked email addresses as wrong and recorded a Tracker note with the name of the operator who ran BOD. Starting in April 2023, instead of simply marking them as wrong, we now delete the email address and put it into the Tracker note. A record is also written to the CUFMAINT file maintenance log with the ID of the system operator who ran the process. If the system receives an out of office message, that address is not changed.
This process is done in batches, generally twice a month on the 2nd and 4th Wednesday of each month, for all online (CU*Answers & Site-Four) and self processing credit unions.
