Q27. You want sendmail to deliver mail for these users:
John.smith@acme.comto mailbox jsmith1
John.smith@foo.comto mailbox jsmith2
John.smith@bar.comto mailbox jsmith3
In which sendmail configuration database can this requirement be defined?
A. /etc/aliases
B. /etc/mail/userdb
C. /etc/mail/virtusertable
D. /etc/mail/domaintable
E. /etc/mail/genericstable
Answer: C
Explanation: /etc/mail/virtusertable
This database file maps mail addresses for virtual domains and users to real mailboxes.
These mailboxes can be local, remote, aliases defined in /etc/mail/aliases, or files. This
allows multiple virtual domains to be hosted on one machine.
The following example demonstrates how to create custom entries using that format:
root@example.com root
postmaster@example.com postmaster@noc.example.net
@example.com joe
