Wildcards are not working for the domain part in Local Bad Sender Domains.
An entry like domain???.com that would match domain123.com, domainabc.com and domainxyz.com is required.
The documention indicates that * or ? wildcards can be used to match any portion of the address.
The documentation wrongly states that wildcards can be used to match any portion of the address. Wilcards are only allowed on the local part of the address ([email protected]) as the examples included into the documentation show.
Symantec will correct the documentation on a future release of the product.
