The POP account that was deleted was one of a
number of POP accounts that had an Alias pointing to it. When the POP
account was deleted, incoming mail for the Alias would create an error
when attempts were made to deliver it to the no longer existing POP
account. This error spawned a number of retry attempts. Each retry
attempt tried to deliver to the non-existing (deleted) POP account and
all of the other POP accounts that the Alias points to. Thus, all of the
existing POP accounts that
had the Alias pointing to them received multiple copies of the same
email; with the number of copies corresponding to the number of retry
attempts made before the system stopped trying.
To remedy this situation, it is nessesary to modify all the aliases that
have an entry for the non-existing POP account. It is normally possible
to do this through the webmail interface; however, this occasionally
requires the assistance of an email administrator. The best solution to
this problem is to make sure that it never occurs in the first place by
ensuring that Aliases are updated prior to deleting a POP account.
