Use the e-mail address policies to mask e-mail addresses.
Two policies are available: auto-generated e-mail name and formatted
e-mail name.
Auto-generated e-mail name
The auto-generated e-mail name policy generates an e-mail
address with a user name based on a literal concatenated with a sequential
number. The sequential numbers are suffixes that begin with 1 and
are incremented by 1. The policy uses the domain name from an e-mail
address in a specified source attribute.
Formatted e-mail name
The formatted e-mail name policy generates an e-mail address
with a user name based on values obtained from one or two attributes.
The policy uses the domain name from an e-mail address in a specified
source attribute.
